For the forum there is an exciting year ahead as the software was upgraded in October and<br />
now also includes a content management system (CMS). The forum upgrade was a success<br />
and painless thanks to Andie Johnson’s planning and hard work. The CMS will give forum<br />
members the ability to organise and share information on <strong>mantis</strong>es in an easily accessible<br />
way.<br />
I am very pleased that for this issue of the <strong>newsletter</strong> Stefan Engelhardt has written a<br />
detailed guide to keeping the Malaysian Dead Leaf Mantis (Deroplatys desiccata). This large<br />
and impressive species is popular in culture appearing in the top ten of the species kept in<br />
culture list (Newsletter no. 5). Stefan has kept this species for around 2 years. Currently his<br />
first generation adults are in the process of mating and ooth laying. (The first generation is<br />
the progeny from a first breeding but is sometimes confused with the parents which are<br />
generation zero.).<br />
Inbreeding issues have arisen on the forum on a few occasions and have always resulted in<br />
heated discussions as this is a complex and difficult issue. Chun Siew has written an article<br />
on inbreeding and how it relates to <strong>mantis</strong> keeping that helps us understand why this is such<br />
a controversial issue.<br />
For the New Year we have an article on caring for new nymphs by Kirobella. This detailed<br />
piece shares Kirobella’s many years of breeding experience and contains details of interest<br />
to more experienced keepers as well as providing a good start for new keepers.<br />
Over the past year members have entered breeding reports into a thread and these have<br />
been summarised for this issue of the <strong>newsletter</strong>. I think the collection of reports of matings<br />
and hatchings and the details, particularly hatch number, has been very successful. I hope<br />
that this will continue in 2012. A finding that is a possible cause for considerable concern is<br />
that Thesprotia graminis might be having difficulty being maintained in culture (see page 18).<br />
The problem could be due to special breeding conditions required by the species or to an<br />
inbreeding ‘bottleneck’. I hope that members with this species might get together to discuss<br />
if there is a problem and what can be done. Nico has submitted a breeding report for the<br />
<strong>newsletter</strong> for Thesprotia graminis including records from an unfertilised ootheca. I have a<br />
particular interest in reports of parthenogenesis and this report adds to the only other report<br />
in this species.<br />
Andie Johnson is developing a species database for reports. This will be a unique database<br />
as it will be the only one where members’ records can be combined for each species in<br />
culture. This will be a long term project that will hopefully get underway in 2012. I believe that<br />
with our large active membership and the number of members who keep records, or are<br />
happy to note stages and sizes of the species they keep, it will develop to be a useful ‘one of<br />
a kind’ resource for <strong>mantis</strong> keepers.<br />
For the end of the year I have compiled what I believe is a fairly comprehensive list of<br />
abstracts from 2011 Mantodea related published literature and a forum digest.<br />

Captive Husbandry of Deroplatys desiccata, the<br />
Giant Dead Leaf Mantis<br />
Stefan Engelhardt<br />
Scientific classification<br />
Kingdom: Animalia<br />
Phylum: Arthropoda<br />
Class: Insecta<br />
Order: Mantodea<br />
Family: Mantidae<br />
Genus: Deroplatys<br />
Species: Deroplatys desiccata<br />
Common names: Giant Dead Leaf Mantis, Malaysian Dead Leaf Mantis<br />
Distribution: Malaysian Peninsula, Sumatra, Java, Borneo<br />
Natural habitat: tropical rainforest, damp areas, on ground with dead foliage, bushes<br />
According to Ehrmann (2002) 11 different Deroplatys species are known; these can all be<br />
found in Southeast-Asia. Just four of them are established in culture (more or less<br />
successfully captive bred): D. desiccata, D. lobata, D. truncata and D. trigonodera.<br />

Deroplatys desiccata, also known as the Giant Dead Leaf Mantis, is a large sized <strong>mantis</strong>.<br />
Adult females reach up to 10 cm and the adult males have very long wings making their<br />
adult size 7-8 cm. These long wings allow males to develop into extremely skilful fliers.<br />

An impressive threat display, bizarre and dead foliage-mimicking appearance together with<br />
high aggressiveness towards prey animals make this species a valuable addition to any<br />
<strong>mantis</strong> keeper’s/breeder’s collection. The most characteristic body part by which the different<br />
Deroplatys species can be distinguished is the large pronotum. Deroplatys desiccata is<br />
considered to be the easiest species of the genus Deroplatys to keep and breed, but some<br />
experience in <strong>mantis</strong> keeping will prove to be advantageous. My Deroplatys desiccata stock<br />
is derived from IGM15 and at the moment I keep several adults of my first generation. In this<br />
little caresheet I will present information about successful husbandry of this beautiful species<br />
and I will include my observations and advice in order to show that, given proper conditions,<br />
Deroplatys desiccata is one of the most rewarding <strong>mantis</strong> species.<br />
Ootheca incubation<br />
Some days after being laid the ooth should be carefully removed from the female’s<br />
enclosure. From plastic surfaces they can be easily detached. It is more difficult when they<br />
are laid onto mesh or bark. In this case the best you can do is to transfer the ooth together<br />
with the mesh/bark into the hatching box. I have used 350 ml (12 fl. oz.) plastic cups with<br />
mesh on the top onto which I have glued the ooth. Wet kitchen towel on the bottom supports<br />
a constant humidity which should also be increased by daily misting. For Deroplatys sp. it<br />
cannot be emphasised enough that a too low humidity will result in a non-hatching ooth.<br />
After incubating the ooth over a period of 40-50 days between 27-30 o C (and a drop to<br />
approximately. 20 o C during the night) a minimum of 30 nymphs and up to 60 nymphs will<br />
hatch. Unlike hatchlings of other species that hang from a thread, Deroplatys desiccata<br />
nymphs shed their pre-nymphal skin immediately after emerging from the ooth, which<br />
explains why ooths are laid sometimes at ground level on dead leaves or bark openings.<br />
High humidity will also avoid nymphs becoming stuck during hatching. Compared to lots of<br />
other species, the hatch itself doesn’t happen in the morning: According to my observation<br />
nymphs hatch between early and late afternoon (this might be explained by their origin: the<br />
rainforest, their natural habitat, offers the best conditions for hatching in terms of humidity in<br />
the afternoon due to the daily rain).<br />

Nymph care<br />
First instar nymphs are comparably big, so they should be fed with Drosophila hydei fruit<br />
flies which they will take already one day after hatching. Interestingly, the characteristic<br />
pronotum is already obvious at this early developmental stage. The most important<br />
parameters one has to consider during nymphal development are ventilation and humidity. It<br />
is crucial to provide an enclosure that ensures high ventilation as very young nymphs can<br />
die very quickly in a damp environment. It is not enough to put mesh just on the ceiling, at<br />
least one side should be permeable to air. Since 1 st instar nymphs are not that aggressive to<br />
each other (given a good supply of fruit flies), I keep hatchlings together in BraPlast-Boxes,<br />
185x185x190 mm (LxWxH):<br />

Wet kitchen towel on the bottom ensures<br />
a constant humidity which is increased<br />
every night by misting (I have used also<br />
vermiculite and was very satisfied with it.)<br />
This misting also serves as freshwater<br />
source: Young and also older instars<br />
often drink from water drops on<br />
branches, mesh or walls. For decoration<br />
and climbing support I provide willow<br />
branches and raffia (the latter has to be<br />
changed regularly along with the kitchen<br />
towel due to mould). The kitchen towel<br />
might also serve as a cushion for<br />
nymphs that fall during moulting.<br />
After about 2 weeks the nymphs moult the first time. It has to be noted that Deroplatys sp. in<br />
general do not grow quickly, especially the sub adult stage can last up to 2 months. From 2 nd<br />
instar on nymphs can feed on houseflies, from 3 rd instar on greenbottle flies and from 5 th<br />
instar on bluebottle flies. I provide some food variation by occasionally feeding them Dubia<br />
roaches (Blaptica dubia), locusts and mealworms. Despite former reports that Deroplatys sp.<br />
prefer crawling prey, it is my experience that flying prey is taken, at all instars, with the same<br />
enthusiasm as crawling prey. When a moult is imminent all prey animals, especially roaches<br />
and locusts, should be removed from the enclosure. In order to avoid mis-moulting you have<br />
to make sure that nymphs have enough space downwards (this means the enclosure should<br />
be at least 3 times the nymph’s length in height). Sometimes nymphs moult too close to the<br />
bottom resulting in a bent thorax in the best case. This is mostly an indication of a too low<br />
humidity and/or a lack of proper moulting surfaces in the upper part of the enclosure.<br />
Additionally, even from an apparently perfect position to moult, nymphs might fall during<br />
moulting. If you are lucky to be around when this happens, the nymph can be rescued either<br />
by hanging it back on the mesh or by holding it carefully with tweezers from the very end of<br />
their legs (the latter requires some patience and a calm hand).

Reliable sexing works from 3 rd instar on by checking the shape of their pronotum. Male<br />
nymphs show a 20 pence-like shield, while female nymphs develop an M-shaped pronotum:<br />

Another possibility for distinguishing the genders is to look at the lower abdominal segments.<br />
Females have a big last segment (in total 6), the males’ last segment is divided (a total of 8<br />
lower abdominal segments). This way of sexing works reliably from 4 th instar on. With a bit of<br />
experience 3 rd instar nymphs can be easily sexed, even without having both genders for<br />
direct comparison.<br />
From 3 rd instar onwards I keep nymphs separately in a 350 ml cup, from 5 th instar onwards in<br />
a 600 ml cup, and from sub adult I use BraPlast-Boxes as enclosures (all the different<br />
container types are shown above). Due to their aggressiveness I would recommend keeping<br />
nymphs separately, especially if only a few nymphs are present. Females should generally<br />
be kept separately. The development from hatch to adulthood takes, dependent on the food<br />
supply, around 6 months or more. Nymphs can adopt a variety of colours, from red-brown to<br />
grey-brown to dark-brown/black. How these colours are determined is, as with other species,<br />
not well understood. I kept all of my nymphs in equal conditions and background colours and<br />
obtained differently coloured morphs indicating that nymph colour is influenced to a large<br />
extent by their genes. As mentioned above, especially the sub adult stage can last for more<br />
than 2 months. Before their final moult nymphs stop eating for around a week and in<br />
comparison to other species it is quite hard to guess when this moult exactly will start: The<br />
swollen wingbuds are a clear sign of the imminent final moult, however extensive pumping of<br />
the abdomen is visible only minutes before.<br />

Females will moult 8 times, males one time less. This is an important point for breeders. If<br />
you intend to breed nymphs that hatched from the same ooth, it is advisable to slow down<br />
the development of the males to make sure that both genders reach adulthood at least at the<br />
same time or, even better, the females become adult first.<br />

Breeding<br />
Adult females need 4-6 weeks before serious mating attempts should be started. I have not<br />
observed the “calling” of females earlier than 4 weeks after the last moult. If you try to<br />
introduce a male too early, in the best case the female will reject him, in the worst case she<br />
will eat him. This 4-6 weeks period is necessary for the female to fatten up and to produce<br />
eggs and ooth material inside of her body and a male introduced too early might be mistaken<br />
as prey. Once you see the female “calling” or if she has been an adult for at least 4 weeks<br />
and has gained weight, the male (adult for at least 2-3 weeks) should be put on a surface or a<br />
branch and left in peace. Some minutes later the female should be put in front of him so that<br />
he faces her abdomen. When she moves and he is in the mood, he will point his antennae<br />
towards her abdomen and will follow her. Usually the male jumps onto the female pretty<br />
quickly and it doesn’t take long for him to connect. The total mating time is rather long and he<br />
might be connected with the female for more than 24 hours. Afterwards he often stays on her<br />
back for some hours until he eventually leaves. I would recommend mating them outside their<br />
enclosure to provide enough space for the male to escape. The females are usually not very<br />
aggressive during mating and the males leave them unharmed (at least I haven’t lost any<br />
males due to mating cannibalism yet).<br />

It takes quite a while for the female to lay the first ooth after mating. Up to 4 weeks is not<br />
unusual. Further ooths are laid after 3-4 week intervals. A total of 7-10 ooths can be laid<br />
7<br />
www.uk<strong>mantis</strong><strong>forums</strong>.co.uk
<strong>UK</strong>MF Newsletter issue 6<br />
during a female’s lifetime. Since males are long-lived (up to 6 months) females should be remated<br />
after the 4 th ooth to make sure that all subsequent ooths contain fertilised eggs.<br />
Summary<br />
Given proper conditions and regular food, Deroplatys desiccata will prove to be not more<br />
difficult to keep than other species and will definitely add to each keeper’s collection. The<br />
extremely long-lived females, that can easily live for more than a year as adults, offer a great<br />
possibility to enjoy keeping this particular <strong>mantis</strong> species longer than others and to learn even<br />
more about their behaviour. Like all praying <strong>mantis</strong>, Deroplatys desiccata is a master of<br />
camouflage and the merging with background shapes and colours is as much an eye-catcher<br />
as their impressive threat displays:<br />

Is Inbreeding Bad?<br />
Chun Siew<br />
<strong>UK</strong>MF Newsletter issue 6<br />
It is a common assumption that inbreeding is ‘bad’ for a species. We were taught this at<br />
school and we, as humans, avoid and frown upon breeding with our close relatives, so it is<br />
easy to conclude that inbreeding is ‘bad’. Following on from this theme, many animals and<br />
plants have evolved rather sophisticated mechanisms to avoid inbreeding. Such<br />
mechanisms are even evident in our beloved Order the Mantodea and it is not uncommon to<br />
find females of some species undergoing several more instars than their male counterparts.<br />
For example, in several flower mantids from the family Hymenopodidae, such as the orchid<br />
<strong>mantis</strong> (Hymenopus coronatus) and the banded flower <strong>mantis</strong> (Theopropus elegans), sexual<br />
dimorphism is very obvious with males undergoing several less instars before maturing than<br />
their sisters. By the time a female matures into an adult, her brothers would have moulted<br />
into adults several weeks or months ago. As adult males do not live very long, particularly<br />
with these species, they would normally die before their sisters can reach sexual maturity.<br />
By maturing at different times, the probability of siblings fertilising each other is greatly<br />
reduced.<br />

So why did these mechanisms evolve? What are the real disadvantages of inbreeding? In<br />
this article, I aim to summarise my experiences and explore basic theories in evolution, and<br />
discuss whether inbreeding has any detrimental effect on captive mantids and see how we<br />
can apply these theories to <strong>mantis</strong> husbandry and breeding.<br />
Inbreeding can be detrimental by increasing the probability of detrimental mutations and<br />
genes being passed on, which can reduce the fitness of offspring. Let’s imagine there was a<br />
small population where inbreeding was unavoidable and that individuals were susceptible to<br />
genetic diseases or defects. Over time in this small population, these disease-susceptible or<br />
detrimental genes accumulate and over generations of inbreeding, the probability that your<br />
offspring inheriting these genes becomes increasingly likely with every generation. Such a<br />
scenario is not uncommon and unfortunately occurs quite commonly in pedigree dogs and<br />
many of our domesticated animals.<br />
Apart from the accumulation of potentially detrimental genes, another big issue with an<br />
inbred population is the lack genetic diversity between individuals in the population. This<br />
means that the probability of you sharing your genes with another individual in the population
<strong>UK</strong>MF Newsletter issue 6<br />
becomes increasingly high in comparison to the probability in a randomly and selectively outbreeding<br />
population.<br />
Why is it necessary to have genetic variability? What are the advantages of having a<br />
highly diverse and varied gene pool?<br />
To highlight such example, here is an extract from Wikipedia: “George C. Williams gave an<br />
example based around the elm tree. In the forest of this example, empty patches between<br />
trees can support one individual each. When a patch becomes available because of the<br />
death of a tree, other trees' seeds will compete to fill the patch. Since the chance of a seed's<br />
success in occupying the patch depends upon its genotype, and a parent cannot anticipate<br />
which genotype is most successful, each parent will send many seeds, creating competition<br />
between siblings. Natural selection therefore favours parents which can produce a variety of<br />
offspring.”<br />
High genetic variability and diversity can help improve a population’s chances of exploiting<br />
untapped resources or new environments. When resources are exhausted in a given area,<br />
competition increases and individuals may then be forced to migrate to other areas in search<br />
of available resources. However, these resources can be in areas subjected to harsh<br />
environmental conditions or treacherous with predators. Those individuals within a<br />
population that can adapt morphologically and behaviourally to these new environments can<br />
therefore exploit these new resources and survive to reproduce and eventually spread their<br />
genes. In a way diversity and variability offers the population more ‘chips ‘to bet with’ and a<br />
population with the most chips to begin with will have the highest probability of winning big. If<br />
the gene pool is diverse, then there is a greater chance that individuals from this population<br />
can adapt to their new conditions and exploit the riches. These individuals carrying genes for<br />
these advantageous adaptations can therefore survive, mature into adults, reproduce and<br />
produce fitter and more offspring. Over time these adaptations become fixed into the<br />
population’s gene pool, as those lacking the advantageous gene sets would be outcompeted<br />
by those better adapted. By having variability, you are increasing the probability of your<br />
offspring’s ability and potential to adapt to changing environments. Such process is called<br />
natural selection, and this does not happen over one generation but through several or many<br />
generations.<br />
However, genetic diversity can be the deciding factor of whether a population<br />
survives, thrives or goes extinct.<br />
The Red Queen Hypothesis based on a reference to the Red Queen in the novel Alice and<br />
Wonderland, uses the analogy depicting the race between Alice and the Red Queen;<br />
describing nature’s evolutionary arms race. The author compares Alice’s race with those<br />
faced by practically every organism between pathogens, parasites, and predators and their<br />
hosts and preys. There is always a conflict between the exploited and the exploiter. The prey<br />
and the host, the exploited, will always try and stay one step ahead of their exploiters<br />
(predators and parasites) by evolving better immune systems or defence mechanisms. As a<br />
result, there is an ongoing cycle as the exploiters are forced to evolve better mechanisms to<br />
exploit their prey or host and so forth. This cycle is called the evolutionary arms’ race. In<br />
evolutionary terms, this is essentially a race between the exploiters and the exploited. As<br />
pathogens and diseases can wipe out entire populations; this can pose a serious problem to<br />
10<br />
www.uk<strong>mantis</strong><strong>forums</strong>.co.uk
<strong>UK</strong>MF Newsletter issue 6<br />
populations that lack genetic diversity and variability. If a population lacks genetic diversity,<br />
pests and diseases can easily exploit the population. In a genetically varied population, it is<br />
harder for the pathogen to exploit all the different combination of genes present. For<br />
example, it’s harder to win a game of lottery when you have to get all 10 numbers right as<br />
opposed to only getting all 3 numbers. During a disease outbreak in a genetically diverse<br />
population, susceptible individuals will die, however, not all the population is susceptible and<br />
the resistant ones will therefore survive and have a higher probability of spreading their<br />
genes. In a closely related population with no genetic diversity, there is no spectrum of<br />
resistance or immunity; all individuals are either susceptible or resistant. Therefore, parasites<br />
and pathogens can be important selective agents in a population. In addition, many empirical<br />
studies have also shown that high genetic variation in honeybees can be correlated with<br />
lower disease prevalence and increases in colony growth rate, suggesting the benefits of<br />
genetic diversity in preventing malignant infections and reducing parasite transmissions. This<br />
helps explain why natural selection has favoured out-breeding and a diverse gene pool over<br />
inbreeding in many animals and plants.<br />
A good example is the evolution of polyandry (mating with multiple males) in honeybees.<br />
One mating from a male can keep the virgin queen fertilised for the rest of her life, yet mated<br />
queens brave the elements and risk predation in order to mate again. In one particular case,<br />
a researcher documented one female that had mated with 100 males. Further empirical<br />
studies have shown that genetic diversity and variability can mean the survival of a colony of<br />
bees, which helps explain why these queens take considerable risks to leave the safety of<br />
her nest to mate with more males.<br />
So inbreeding is bad right?<br />
There are good reasons to assume that inbreeding is bad and detrimental. However, it is<br />
wrong to assume that inbreeding is detrimental to all animals. For example, many animals<br />
including insects and even mammals are inbred, such as termites (read up on diplodiploidy<br />
for those who are interested), parasitic wasps, the African naked mole rat and even our<br />
beloved felines and canines. Therefore, we need to consider whether inbreeding is<br />
detrimental on a case-by-case basis.<br />
There’s no denying the benefits of genetic variability and diversity, but this depends<br />
on the circumstances.<br />
Inbreeding has played a big role in domestication and selective breeding for desirable traits<br />
in dogs, cattles, pigs etc. It is even used by plant breeders to select for disease, pest and<br />
drought resistant crops for example. Inbreeding can also be equally important in fixing<br />
beneficial genes in the population, which is why traits for antibiotic resistance can spread<br />
extremely quickly within a population. In other words, once resistance or a beneficial trait<br />
evolves, the offspring or clone is almost guaranteed to inherit those sets of beneficial genes.<br />
However, crossing of genes as a result of sexual reproduction means there is only a 50%<br />
chance that gene would get passed onto your offspring (unless both your parents possess<br />
the beneficial trait). Similarly, inbreeding can also be advantageous, as useful mutations<br />
such as resistance to a particular disease can be passed on to the next generation very very<br />
quickly, whilst out breeding increases the chances of your resistance genes being mixed up<br />
with susceptible genes and diluting the advantageous resistance. In insects with shorter<br />
11<br />
www.uk<strong>mantis</strong><strong>forums</strong>.co.uk
<strong>UK</strong>MF Newsletter issue 6<br />
generation times, such advantageous genes can be accumulated at a much quicker rate<br />
than for example a mammal, which is why pest insects can become resistant to insecticides.<br />
So how does this relate to breeding mantids?<br />
I remember when I first started keeping mantids people were claiming that they were<br />
experiencing the effects of inbreeding in species such as Gongylus gongylodes, with low<br />
hatch rates, random deaths, uninterested males and females laying dud oothecae. However<br />
we can’t say for sure whether this was true or hobbyists simply pointed their finger to<br />
inbreeding (as it is pretty easy to do so especially when a <strong>mantis</strong> dies ‘for no reason’).<br />
I will let you make your mind up on this topic, but from my experience, I believe that under<br />
certain circumstances, inbreeding can actually be beneficial.<br />
By keeping a <strong>mantis</strong> in captivity, we have to understand that we are providing them with an<br />
'unnatural' environment. We provide them with a limited range of temperatures, humidity,<br />
food items and subject them to artificial lights and photoperiod. Along with these unnatural<br />
conditions, how many of us can say that we had more than 20 breeding individuals to breed<br />
with? By using such a small number of individuals we are creating a bottleneck effect. We<br />
are inadvertently providing a selective pressure when keeping and breeding mantids in<br />
captivity. Think back to the natural selection. In this new artificial environment, those<br />
individuals that can adapt, survive and breed in these environments will continue to survive<br />
and reproduce, whilst those that are the most sensitive to environmental (and physical)<br />
stress will die and fail to reproduce. If a certain stock is doing fine, the introduction of new<br />
genes into the gene pool can be more detrimental than advantageous contrary to popular<br />
belief. Even if both stocks came from the same country, one cannot assume that they both<br />
came from the same location or are adapted to the same environment/microclimate. This is<br />
one of the reasons why IGM had been set up, so people can keep track of their stocks and<br />
its origin. For those interested, I suggest going back to the first issue of the <strong>newsletter</strong> and<br />
reading Christian’s IGM article (rather than having to repeat what he has written).<br />
Realistically, the majority of people on the forum are casual hobbyists. How many of us can<br />
say we have bred a particular species for more than 5 or even 3 generations? Most people<br />
either get rid of their stock or move onto another species after several generations. If this is<br />
the case, the probability you will encounter any problems from inbreeding is close to zero.<br />
However inbreeding can contribute to whether a newly introduced line will persist or ‘go<br />
extinct’ in the hobby, which is why we should consider whether inbreeding is detrimental on<br />
a case-by-case basis. Under such circumstances, it seems like inbreeding can actually be<br />
beneficial, although I base this all on my experience.<br />
This was a topic for a rather heated debate on <strong>UK</strong>MF earlier this year and I thought it would<br />
be interesting to revisit the issue with an open mind. The difficulties breeders face when<br />
introducing a new species in the hobby and making sure that it will still be around in years to<br />
come is finding the balance between establishing as much genetic diversity as possible from<br />
a small group of captive stocks but yet ensuring that introduction of genes from wild<br />
specimens do not reset the gene pool of captive populations to captive environments. This is<br />
no easy feat and this is probably why many of the new species that get introduced into the<br />
hobby never get establish and die out before they can become widely available to everyone.<br />

It is difficult to say whether a species failed to establish in culture after a few years is a result<br />
of limited genetic variability. There are many reasons why stock die out, especially when<br />
working with such a small number of breeding individuals, stochastic (random) events<br />
become a very important factor in influencing whether a species persists or perishes from<br />
culture. These are random events, which can cause a substantial consequence on a<br />
population. In the wild, these include sudden drought, an introduction of a non-native<br />
predator, freak weather etc. For example, the marine iguana populations were threatened to<br />
extinction as a result of the El Nino in the Galapagos. In captive conditions, the stochastic<br />
event is us. We are humans after all, and no one can say they have never made a mistake.<br />
The issue of whether genetic diversity is necessary in <strong>mantis</strong> husbandry is complex. In<br />
summary, when genetic variability is high, adaptation to new environments occurs quicker.<br />
Over several generations, a particular stock can become adapted to the artificial conditions.<br />
When we eliminate predators, parasites and diseases and provide our beloved mantids with<br />
suboptimal conditions and a constant supply of food, this allows more individuals with<br />
different genotypes to survive and reproduce. Mutations still occur and over time the genetic<br />
variability increases because the environment is no longer a selective pressure as the stock<br />
becomes acclimatised to artificial conditions thus more individuals make it to adulthood and<br />
reproduce. When a species remains in a hobby for several generations, the captive<br />
population becomes increasingly adapted to the environmental conditions we provide. I am<br />
not suggesting that introducing new blood to the gene pool is bad, but if it is unnecessary, I<br />
think it’s best working with what we’ve got instead of having to constantly rely on collecting<br />
new ‘blood’ from the wild.<br />
I hope this article has stimulated some thoughts into this topic.<br />

Mantid Nymph Care: A Personal Overview<br />
Kirobella<br />
After a mantid has successfully mated, a fertile ootheca laid and the incubation requirements<br />
of ventilation, humidity and heat have been met, a handful or more nymphs will need<br />
attention. All three mentioned elements are key to the growth and survival of nymphs. Each<br />
can be critical to such delicate creatures – especially in the first week or so of their life.<br />
After hatching from an ootheca nymphs need to harden off the chitin exoskeleton which<br />
protects them. The surface of the exoskeleton becomes rigid after a while which, for<br />
example, allows the legs to set properly. A good circulation of clean air is necessary but<br />
drafts should be avoided.<br />
A collection of various dud and spent oothecae (left) and a female Hierodula<br />
unimaculata laying an ootheca (right).<br />
I have found nymphs will quench their thirst twenty four hours or so after hatching with a very<br />
light fine mist spray. Preferably the water would have been left to stand for twenty four hours<br />
prior. It should neither be too cold or too hot – tepid is best. This very fine misting will be<br />
sufficient for their small mouthparts and avoids the water from forming into larger droplets in<br />
which the nymphs can drown. I will repeat spray three to four times on the very first day<br />
before any prey item is offered to them. Use your judgement to see that indeed the first<br />
misting has evaporated before continuing with successive watering. Excess humidity can<br />
lead to an accumulation of moisture especially if the first factor of ventilation is not met.<br />
Furthermore, large moisture droplets can prove fatal to a nymph.<br />
To maintain a background level of humidity some use a simple plastic box, such as those<br />
obtained from the purchase of a box of locusts for example, which has small perforations in it<br />
and to which further holes can simply be added. A sufficient wad of kitchen roll or fabric that<br />
has been wetted and placed in the box can be used to maintain the humidity. Note that the<br />
14<br />
www.uk<strong>mantis</strong><strong>forums</strong>.co.uk
<strong>UK</strong>MF Newsletter issue 6<br />
lid to the box is secured too. Some of the material may also be teased through a small hole<br />
in the plastic so as to provide for a drinking platform if needed. Emphasis to this last point is<br />
that when I have kept a hatch communally there always seem to be a number of nymphs<br />
that will permanently occupy a lower niche in the enclosure and it is for their benefit to which<br />
I address this tendency. Often branches, leaves and other footholds will block an adequate<br />
fall of spray without a more heavier ‘drenching’ since I will only mist from the top.<br />
A warm ambient temperature is beneficial for all mantids, some requiring more heat than<br />
others but generally not until they are more developed in further instars. This will be very<br />
relevant for us members here in the United Kingdom having a temperate climate, which is<br />
variable even upon summer days as well as when in the year an ootheca hatches.<br />
Hatching S. aurea nymphs (left) and a fine spray mist dispenser (right)<br />
I have found that most oothecae hatching in the spring or early summer will see nymphs not<br />
requiring additional heat sources and that the mean temperature day and night is suitable.<br />
Nymphs are quite delicate and additional heat is not always necessary, although heat will aid<br />
humidity as well as in general increasing metabolic rate and in turn that drive to feed and<br />
thus grow. Another factor is the size of the enclosure and the material from which it is made<br />
which will add to the overall equation of the nymphs’ husbandry, if indeed additional heat is<br />
used. Nymphs within a heated ‘insect room’ are fine but the last issue concerns those that<br />
only have one or more separate enclosures to look after and may be thinking of using heatmats<br />
etc.<br />
With many species having nymph numbers reach one hundred or more a suitable enclosure<br />
is required. I cannot emphasise the importance of the previous three elements which may<br />
well optimise the success rate which you will experience raising such nymphs and these will<br />
influence your choice of enclosure. Of course, if a spare large glass or plastic tank is at hand<br />
then I’m sure that would suffice. Not all species need nymphs separated as to avoid<br />
cannibalism and many will co-habit up to around 5 th instar or more. This is especially true of<br />
most Sphodro<strong>mantis</strong> species.<br />

I recommend the fishing<br />
ring-net enclosures which<br />
can be found for as little as<br />
one pound in high street<br />
outlets. These provide<br />
ventilation, can be mist<br />
sprayed from the outside<br />
and hung from a ceiling out<br />
of the way. A slow rainfall<br />
of faeces will over time<br />
accumulate though. . Be<br />
sure to check that the<br />
mesh size is adequate to<br />
prevent the escape of fruit<br />
flies. I have one type that<br />
has a very fine triangular<br />
weave whilst others have<br />
hexagonal, round or square<br />
weaves.<br />
A cheap £1 ring net 60 cm x 30 cm (left). A slit on one side approximately one straws<br />
width for feeding (right) and a close up of the triangular weave of the ring nets I find<br />
best.<br />
When I use these ring nets I will cut a small hole in the lower side of the netting, one along<br />
the hem of the net where the two ends meet, and then sew the top and the bottom of the<br />
said to stop the slit from widening. The slit is just a sufficient size to allow a drinking straw to<br />
pass through it (or the tubing from a pooter). Fruit flies are fed into the chamber via this<br />
opening. A small safety pin provides to close it when not in use.<br />
With the approach of an expected hatch the breeder has to be prepared. An essential and<br />
often much overlooked item is the availability of prey. One should establish a good few<br />
batches of fruit fly cultures beforehand. All nymphs will take fruit flies. What I find convenient<br />
with fruit flies is that because they are so small they will not disturb a nymph during ecdysis.<br />
A few have reported that a nymph has fallen during such a process resulting from blue or<br />
green bottle fly action. I will use fruit flies for as long as possible – in some instances right up<br />
until 4 th instar depending upon species. There are many online outlets from which fruit flies<br />
are obtainable, or any good pet store, provided an order<br />
is placed and perhaps paid for prior.<br />
As the nymphs grow and develop into larger instars,<br />
larger prey items such as wax worms and moths, green<br />
and blue bottle flies, maggots, hatchlings and small<br />
locusts will be needed. The need to feed them will<br />
eventually become apparent if the cannibalism rate<br />
increases. I tended to leave a batch of fly castors in a<br />
tub that hatched so many every day and topped this up
<strong>UK</strong>MF Newsletter issue 6<br />
with further castors that had been kept cooler. A variety of other prey was offered every<br />
week.<br />
I have used the frame from a flexarium here covered with a finer net to house a batch of<br />
Rhombodera basalis. The net size prevented fruit fly escape. I later attached thin ribbons of<br />
the same netting to the ceiling and left them to dangle so as to provide a greater surface<br />
area for the nymphs to occupy.<br />
Left: A couple of potted Guzmania bromeliads placed on a wet tea towel within<br />
the net flexarium. Right: Two flexariums placed one on top of the other to<br />
accommodate two different hatches. Both have Lawsons cypress branches within. The<br />
upper unit shows also a tub of green bottle castors which were placed within and allowed to<br />
hatch in the heat of the summer.<br />
Later in the season a few artificial stems were suspended from the ceiling of the net<br />
enclosure to provide a greater surface area for the spatial distribution of the nymphs. This<br />
allowed them to occupy a niche, to catch prey and ecdyse and minimise disturbance from<br />
each other and prey.<br />

26 species of captive bred nymphs were offered for sale in the classifieds during the last 4<br />
month period. In total this year nymphs from 46 species were captive bred and offered for<br />
sale on the forum.<br />
At the end of February a forum thread was started to report matings and hatches. The<br />
purpose of the reports was mainly to see if species declining in culture were being lost<br />
because of breeding difficulty or because of lack of breeding attempts. Twenty-one members<br />
entered reports and in addition entered data such as hatch number and incubation time.<br />
Breeding data will vary depending on environmental conditions, parental nutrition and the<br />
number of oothecae a female has laid. However by collecting the data from a number of<br />
keepers the range of typical hatch rates and other data can be determined and added to<br />
care sheets. For example Pseudocreobotra wahlbergii ooths were reported to hatch between<br />
15 and 23 nymphs and Hymenopus coronatus were reported to hatch between 70 and 105<br />
18<br />
www.uk<strong>mantis</strong><strong>forums</strong>.co.uk
<strong>UK</strong>MF Newsletter issue 6<br />
nymphs. A big thank you to everyone who has taken the time to submit these reports, they<br />
will eventually also be submitted into a species in culture database. The results are<br />
summarised in the supplementary table at the end of the <strong>newsletter</strong>.<br />
Some interesting findings from the breeding reports for the year:<br />
� Species that are being very successfully bred in culture at the moment by a number<br />
of breeders are Acontista multicolor Pseudocreobotra wahlbergii, Hymenopus<br />
coronatus, Popa spurca, Deroplatys desiccata, Phyllocrania paradoxa,<br />
Pseudoharpax virescens and Sibylla pretiosa. In most cases at least four different<br />
keepers reported successfully breeding these species, but with Hymenopus<br />
coranatus and Phyllocrania paradoxa this also included two generations reported<br />
over the year. For example Paul MI6 reported a first generation of Hymenopus<br />
corantus in February 2011 and a second generation ten months later in December<br />
2011. The Ghost Mantis (Phyllocrania paradoxa) had the most reports (7) of<br />
successful breeding attempts.<br />
� There could be a problem with breeding Theopropus elegans. Five keepers reported<br />
mating this species but only one reported a successful hatch. For example one<br />
keeper noted ‘Theopropus elegans. Mated, ooths laid and failed to hatch’.<br />
� A hatch was reported of one nymph from a Creobroter gemmatus ooth that was<br />
thought to be infertile. Could this be a possible case of parthenogenesis?<br />
� A Harpago<strong>mantis</strong> tricolor ooth hatched 14 nymphs with one or two nymphs hatching<br />
every day over nine days.<br />
Thesprotia graminis hatching report by Nico<br />
This review is based on three oothecae. Two of them were laid by mated females. One was<br />
laid by an unmated female. My original stock came from a breeder in the USA. He sent three<br />
oothecae from mated females, captive bred by him. I presume his original stock came from<br />
the wild as this species can be found in this state.<br />
Incubation.<br />
� First ooth: Room temperature (25-26°C), humidity level 50-60%, never sprayed.<br />
Incubated for 5 weeks. Hatched 20 nymphs.<br />
� Second ooth: 28°C, humidity level 50%, sprayed every week. Incubated 4 weeks.<br />
Hatched more than 30 nymphs!<br />
� Third ooth (not fertilised): 28°C, humidity level 50%, sprayed every week. Incubated<br />
6-7 weeks. Hatched 3 nymphs.<br />
Nymph care<br />
I gave water to the nymphs immediately after hatching as they appeared to like and need to<br />
drink then. Nymphs were sprayed lightly with water every 2 days, but they can tolerate a<br />
totally dry climate. They were able to catch Drosophila hydei and D. melanogaster fruitflies<br />
without any problem but will look for smaller prey such as springtails. Wood wool seems the<br />
perfect decor for them when they are young. Cannibalism will occur only if there is not<br />
enough food. They do not seem to need much space to achieve successful molting (every 2<br />
weeks). At the time of writing they are now fourth instar (1 st ooth), third instar (2 nd ooth) and<br />
second instar (3 rd ooth).<br />

Forum Digest: 2011<br />
<strong>UK</strong>MF Newsletter issue 6<br />
Following a suggestion from Mrblue I have selected some of the many interesting threads<br />
on the forum. For this issue one thread has been selected from each month. It was hard to<br />
select just one thread from each month as some months had a number of very interesting<br />
threads that should really be included but are not, due to space. In future issues this will be a<br />
regular feature with selected abbreviations of some of the threads. If any member would like<br />
to volunteer to produce a regular forum digest for the <strong>newsletter</strong> please contact me.<br />
January<br />
I thought it would be a good idea to remind everyone about instars with this post from Rob<br />
Byatt in January 2011 when he reposted a post he made on another forum (Bugnation) in<br />
2007. “Okay, as most of you know I'm a traditionalist when it comes to naming the stadium<br />
at which an insect is at. I wish for all posts to describe this stadium as an instar not 'L'. This<br />
is for a reason - it is the correct scientific way. We all know what happened last time I didn't<br />
reference this, so.....The intervals between the ecdyses are known as stages or stadia, and<br />
the form assumed by an insect during a particular stadium is termed an instar. (Imms, A.D.<br />
1964. A general Textbook of Entomology. London: Methuen & Co. inc.. p.222.)" In recent<br />
months I have seen an increasing number of people slipping back to the dark side, hence<br />
this post”<br />
And people are slipping back again, hence the reminder for the New Year here.<br />
February<br />
Drumkitchen (Stefan Engelhardt) began a breeding diary for Deroplatys desiccata in<br />
February that has had over 2000 views to date. This is a very detailed, complete diary with<br />
beautiful pictures and observations and I agree with Kirobella’s post: “Congrats - one of the<br />
best diaries I have read”.<br />
This diary has the full scientific name in the title of the thread and so makes it easy for<br />
people who are searching for information on a species. It is hoped that in 2012 we will begin<br />
to push towards having scientific names in the first instance in a thread as it will help<br />
searches and avoid confusion.<br />
March<br />
In March 94 members submitted a list of the species they were keeping into survey software.<br />
A discussion of the full results can be seen in Newsletter no. 5. A total of 85 species were<br />
being kept and for me a surprise result was that Gongylus gongylodes was the second most<br />
commonly recorded species in culture at the time.<br />
April<br />
In April Cameron Die Konigin posted some pictures of the remarkable Peruvian Shield<br />
Mantis (Choeradodis rhombicollis) that he had described collecting on his trip to Ecuador in<br />
the February 2011 addition of the <strong>newsletter</strong>. “They are slow to grow, presumably because<br />
21<br />
www.uk<strong>mantis</strong><strong>forums</strong>.co.uk
<strong>UK</strong>MF Newsletter issue 6<br />
they put most of their effort into developing the 4.5 cm wide shield (for the female), hence<br />
why they are called shield <strong>mantis</strong> or leaf <strong>mantis</strong>.”<br />
Chun Siew added that he had collected various males in Costa Rica but never managed to<br />
get a female, since they were coming to light-traps rather than hand-collecting as Cameron<br />
had.<br />
May<br />
Mantis Massive started an interesting thread called “Taming the <strong>mantis</strong>” asking whether<br />
people notice if their <strong>mantis</strong>es get accustomed to being handled over time. “If you take them<br />
out of their enclosure for handling when they are nymphs, will it be less of a hassle when<br />
they are full size and you want to mate them? Basically, I don't want to cause my <strong>mantis</strong><br />
nymphs (first to 4 th instar) any extra stress, but am finding that the mere presence of me<br />
peering in at them will sometimes spark quite a full on threat display”<br />
Electrophil, mick-h and strike had all found that their <strong>mantis</strong>es become calmer with regular<br />
handling.<br />
June<br />
Bransckia posted information on the Humbertiella stock currently in culture in the thread<br />
‘Humbertiella "ceylonica" is Humbertiella sp. (IGM 212). “It is the same stock that was<br />
introduced in August 2010 from India. More details are in the IGM List number 212: The<br />
information may help if you are looking for counterparts or more specimens of this<br />
stock/species.”<br />
In the discussion that followed forum members shared their information on the care<br />
conditions they use for this species. Draco wrote that he had a hatching rate of around 30-<br />
40 nymphs but that he had difficulty keeping them healthy. Branskia replied that he had the<br />
same difficulty with raising all the hatchlings. Kovachii and Psychniko also shared their<br />
culture conditions and both used very high humidity with the hatchlings. A more full account<br />
of the culture conditions that these members used can be found in this thread.<br />
July<br />
In the General Mantis Discussions forum Diamorphine<br />
started a thread ‘Male ate our female?’ as it appeared that<br />
her male Ghost Mantis (Phyllocrania paradoxa) might<br />
have eaten the female during mating. In the discussion<br />
that followed there were three further examples of this<br />
unusual behaviour. MantidLord reported that he had an<br />
adult male Iris oratoria which ate the female.<br />
Creobroterman reported that he had seen a<br />
Pseudoharpax adult male munch on the female's thorax<br />
but that he separated them in time and Mylo reported that<br />
a Spiny Flower Mantis (Pseudocreobotra whalbergii)<br />
exhibited "reverse cannibalism” where the male was on<br />
her back and locked onto her and ate her head.<br />

August<br />
Danielbd100 asked for advice on breeding Mantis religiosa after being given two adults that<br />
mated almost immediately. Drumkitchen and Tom Boeije offered good ootheca and nymph<br />
care advice and then the discussion moved onto ooth diapause in this species.<br />
Drumkitchen explained diapause: “For some species, especially the ones to be found in the<br />
cooler temperate regions, a diapause is absolutely crucial for their development inside of the<br />
eggs. Without a cooler period over several months they would never hatch”.<br />
Tom Boeije and creobroterman offered some techniques for incubating ooths in diapause.<br />
By placing ooths into a cooler environment the resting diapause is broken and the ooths can<br />
develop and hatch. This prevents them hatching before the winter frosts.<br />
September<br />
Regularly on the forum we get identification requests for <strong>mantis</strong>es found in the wild. Although<br />
a full identification is not really possible from a picture, suggestions can be made by<br />
members of a possible genus and maybe species when combined with the knowledge of the<br />
location. This was the case when RyoKenzaki asked for identification help for two species<br />
he found in Malaysia. Dessicata suggested an A<strong>mantis</strong> species for one and RyoKenzaki<br />
agreed that seemed possible as the ooth also had the appearance of an A<strong>mantis</strong> ooth.<br />
Christian then suggested Hapalopeza nitens as the other species and agreed the possible<br />
identification of A<strong>mantis</strong>, and suggested it was probably A. reticulata.<br />
October<br />
Birdfly began a thread “Plistospilota guineensis, Mega <strong>mantis</strong>, 3rd time lucky ??” An<br />
interesting observation that he made was that the behaviour of this latest generation was<br />
different to previous generations. “My last male moulted to adulthood successfully last night<br />
so I have 3 adult males and 2 females now. I must say that these 5 are real settled<br />
compared to the 10 I've kept before which would throw themselves to the floor at the<br />
slightest chance, run around like headless chickens and damage themselves until totally<br />
stressed out”.<br />
MrBlue suggested this might be the distance from the wild. Rob Byatt has kept these for<br />
many generations and wrote “The species seems to be settling down a bit at last; they are<br />
becoming easier to rear (notice how many managed that last year compared to previous<br />
years?), but breeding them is still a pain“.<br />

November<br />
Stunning photos of a species new to the forum were<br />
posted in November from two threads started in October.<br />
Kovachii posted pictures of a mating pair of<br />
Parymenopus davisoni. The species is sometimes seen<br />
referred to as Parhymenopus davisoni but<br />
Branksikia.cleared up the name confusion with a<br />
reference to the paper where the name was revised<br />
(Roy, R. 2007. Parymenopus Wood-Mason 1890, et<br />
Cataspilota Giglio-Tos, genres valides (Dict. Mantidae). -<br />
Bulletin de la Societe Entomologique de France 112(1):<br />
p. 89-91).<br />
Chun started a thread Parymenopus davisoni (IGM 230)<br />
in late October with some photographs nymphs and<br />
Mrblue also added photos the interesting comparison<br />
shot shown of a P. davisoni female (above), one moult to<br />
adult and a Hymenopus.coronatus female (below),<br />
perhaps three moults to adult. Hopefully we will see<br />
some more of this species in 2012.<br />
December<br />
For December I have chosen a thread that began at the<br />
beginning of the year and has continued throughout the<br />
year to December. The thread was begun by Lethalhayd<br />
to find out who was still keeping Acanthops sp. IGM 151.<br />
Gurd wrote that his first generation females were still<br />
growing strong after 6 months as adults and gave<br />
breeding and care advice. Chun described breeding this<br />
species and wrote that “The males can be a little rough<br />
when mating and it is not uncommon to see the males<br />
accidentally piercing the female abdomen”.<br />
The thread was quiet for a number of months until.<br />
PaulM16 reported that he had hatching success. Mrblue<br />
wrote that the unusual shape of the females seemed to<br />
confound the males sometimes. PaulM16 replied “I<br />
noticed that on the first 2 mating attempts the female kept her shape fairly 'tight' and fought<br />
off the male aggressively, but on the third attempt she lowered her abdomen as if to signal<br />
that she was receptive to the male and didn’t so much as flinch during his approach”.<br />
In November PaulM16 reported the good news that his third ootheca had the largest hatch<br />
yet with 47 nymphs. This post that began in January ended with success for this species<br />
with this last post of the year by PaulM16. “4th and 5th ooths have also hatched 35 and 38<br />
nymphs respectively. 6th ooth has been sent out to another breeder and my female has laid<br />

the Praying Mantid Hierodula majuscula. Australian Journal of Entomology. 2011, doi:<br />
10.1111/j.1440-6055.2011.00843.<br />
Abstract: Many sensory modes can be exploited to determine the location of potential<br />
mates. In insects, long-distance location primarily involves chemical or acoustic cues,<br />
whereas short-distance communication mainly utilises visual or tactile cues. The structural<br />
complexity of the environment may influence the transmission of information, and therefore,<br />
it is common to see multiple sensory modes employed to increase the likelihood of accurate<br />
mate location. Praying mantids are known to use airborne chemicals for long-distance<br />
location and visual cues in close proximity. This study examined which types of cues are<br />
used for mate location in an unstudied species, Hierodula majuscula, from Queensland,<br />
Australia. The timing of female pheromone emission during ‘calling’ periods reached a peak<br />
at 3:00 h, with the majority of females assuming a calling posture at this time. Scanning<br />
electron microscopy was used to confirm the presence of basiconic sensilla (used for<br />
chemical reception) on male antennae, and males successfully responded to female<br />
chemical cues and subsequently located potential mates. Males were not as successful at<br />
finding females when restricted to using visual cues.<br />

Competition Affects Juvenile Development and Ejaculate Expenditure in Male Praying<br />
Mantids. Animal Behaviour, 2011, 82 (5): 1201-1206,<br />
Abstract: Sperm competition occurs when a female mates with more than one male, and<br />
the sperm of those males compete directly over fertilizing her eggs. In polyandrous animals,<br />
males can respond to the perceived risk of sperm competition by flexibly adjusting aspects of<br />
their development and reproductive investment. In high-risk scenarios we might expect<br />
males to accelerate development so as to mature quickly and locate receptive females first<br />
and/or transfer more sperm so as to outcompete rival sperm. We examined these<br />
predictions using the false garden mantid, Pseudo<strong>mantis</strong> albofimbriata, a medium-sized<br />
praying mantid found on the east coast of Australia. Males are less than half the mass of<br />
females. Sexual cannibalism occurs in up to 40% of interactions, highlighting the importance<br />
of investing optimally in reproductive opportunities for males. We housed juvenile males in<br />
two operational sex ratio treatments: three males, one female (high risk of sperm<br />
competition) and one male, three females (low risk). We found no evidence of accelerated<br />
development in the high-risk group; instead, high-risk males took longer to mature. Possibly,<br />
males exposed to a higher risk of sperm competition delay maturity in order to invest in<br />
testes development and sperm production. We also found that males reared in the high-risk<br />
treatment transferred significantly more sperm than males reared in the low-risk treatment,<br />
providing evidence of strategic ejaculation in male P. albofimbriata. This is the first study<br />
demonstrating a male response to the perceived risk of sperm competition via delayed<br />
development and increased ejaculate investment in praying mantids.<br />

(Mantodea: Acanthopidae). Neotropical entomology, 2011, 40 (4): 462-469.<br />
Abstract: The life-cycle of Callibia diana Stål is described and linear and geometric<br />
morphometrics are used for studying allometrics and shape changes throughout this<br />
neotropical mantid species' life-cycle. Significant changes were expected in the allometry<br />
and shape of the raptorial leg and abdomen, given the importance of hunting and<br />
reproduction. The allometric slopes were obtained by using total length as the independent<br />
variable. Geometric morphometrics of landmarks were used for frontal femur and tibia.<br />
Hunting and reproduction-related structures had the steepest slopes and positive<br />
allometries. Negative growth of both disc width and head width found in the last moulting<br />
event may be a consequence of prothoracic muscle growth which is responsible for<br />
predatory strike strength. The tibial claw and femur of the raptorial leg become larger, while<br />
their spines become more orthogonal to the longitudinal axes which may facilitate prey<br />
retention. These changes in mantid shape throughout ontogeny were consistent and<br />
suggested the resource allocation and development programming of the body that improved<br />
reaching distance and prey retention.<br />

Precedence Patterns and Female Re-mating Frequencies in a Sexually Cannibalistic<br />
Praying Mantid. Evolutionary Ecology, 2011, 25 (1): 107-119<br />
http://dx.doi.org/10.1007/s10682-010-9384-3<br />
Abstract: Scramble competition polygyny is expected when females and/or resources are<br />
widely dispersed and not easily monopolized by males, or when there is an abundance of<br />
mates during an extremely restricted reproductive period. Additional factors such as first<br />
male sperm precedence or low female re-mating rate might further explain the propensity of<br />
males to engage in scramble competition. The sexually cannibalistic praying mantid<br />
Pseudo<strong>mantis</strong> albofimbriata exhibits a polygynous mating system, where females exist in<br />
low-density populations and male competition manifests as the race to find females rather<br />
than as direct physical fighting. Here, we aim to determine whether there is a paternity<br />
advantage for the first-male to mate and/or a low frequency of female re-mating. First, we<br />
determined sperm precedence patterns in P. albofimbriata using the sterile male technique.<br />
Second, we tested the likelihood of female re-mating in P. albofimbriata by comparing the<br />
close-range approach behaviour and frequency of successful mating attempts for males<br />
when paired with virgin as opposed to recently mated females, and by comparing the<br />
frequency of long-distance male attraction between virgin and mated females. We found no<br />
paternity advantage for the first male to mate, rather a second male advantage. Although<br />
mated females were not rejected by males when approached from close-range, they were<br />
chemically unattractive to males searching from a distance. Since initial mate attraction in<br />
many praying mantids, including P. albofimbriata, is mediated via long-distance chemical<br />
communication, we believe the latter result is more ecologically relevant and therefore more<br />
important. These results suggest that the relatively low frequency of female re-mating<br />
observed in P. albofimbriata may be an additional factor driving scramble competition in this<br />
system.<br />

(Insecta, Mantodea). Atti Soc. it. Sci. nat. Museo civ. Stor. nat. Milano, 2011, 52 (I): 25-35.<br />
Abstract: The recent find of an Ameles spallanzania population in a continental area of<br />
northern Italy permitted to redraw the northernmost edge of the distribution of this species<br />
and to study its life cycle in extreme climatic conditions. A comparison with collecting records<br />
of adult specimens from the Mediterranean area has been performed to put in evidence how<br />
this species adapts its life-cycle timings in different latitudes: hatching earlier or using<br />
nymphs to overwinter in warmer localities or oothecae in colder ones. Overwintering<br />
strategies of Ameles spallanzania have been compared with strategies of other genera of<br />
mantids that share the same habitat but have different life-cycle strategies and general<br />
distribution. Different developing times in mantids seem to be linked to behavioural<br />
strategies more than physiological attitudes.<br />

Responses in Praying Mantis. Journal of Insect Behavior., 2011: 1-10<br />
http://dx.doi.org/10.1007/s10905-011-9283-7<br />
Abstract: The aim of the present study was to investigate the distance at which vertical<br />
black and white stripes (contrast boundaries) elicit object-related behavioral responses in 6th<br />
instar and adults of the praying <strong>mantis</strong> Mantis religiosa. The mantids reacted when the<br />
contrast boundaries were not further away than 60 cm. However, with increasing distance<br />
(>20 cm), the contrast boundaries became progressively less significant for the mantids.<br />
Jumps/preparation of jumps could be observed between 10 and 30 cm. The results are<br />
supportive for distance measurement of up to 20–30 cm, which corresponds to distance<br />
accessible for the insect. It seems that image motion cues induced by peering movements<br />
play an important role.<br />

Beier, 1963 (Dictyoptera, Mantidae: Stagmatopterinae): An Unusual Case of “Parasiteinduced”<br />
Synonymy. Zootaxa , 2011, 2735: 31–34<br />
Abstract: The Neotropical genus Parastagmatoptera Saussure includes medium-sized<br />
species distributed in tropical and subtropical areas of Central and Southern America.<br />
Thirteen nominal species have been so far described (Agudelo et al. 2007), with most<br />
species currently known from few specimens, often of one sex only. Beier (1963) described<br />
Parastagmatoptera abnormis Beier, 1963 based on a single male specimen from Surinam.<br />
Unfortunately, Beier’s original description lacks enough details to allow an accurate<br />
literature-based identification and, since its original description, no additional specimens<br />
ascribable to P. abnormis have been recorded. We recently had the opportunity to examine<br />
27<br />

the holotype of P. abnormis, which is deposited in the Biozentrum Grindel und Zoologisches<br />
Museum (ZMH-Hamburg, Germany). After the examination of the holotype’s external<br />
morphology, we believe that the erection of this species was the result of an unusual case of<br />
misidentification. The type specimen exhibits some interesting morphological features that<br />
we believe might have resulted from the activities of an internal parasite, which we describe<br />
as follows.<br />

Molecular Origin and Development of a Panzootic Caused by Beauveria bassiana in<br />
Praying Mantis Populations in Eastern China. Journal of Invertebrate Pathology, 2011,<br />
108, (2): 98-105. (http://www.sciencedirect.com/science/article/pii/S0022201111001121)<br />
Abstract: A panzootic in praying mantid species Tenodera sinensis and Statilia maculate,<br />
caused by Beauveria bassiana, occurred in north, southwest and southeast regions of Anhui<br />
Province, eastern China in Autumn, 2009. A 3-d principal component analysis (PCA) of 123<br />
isolates from three sites revealed that the B. bassiana populations were heterogeneous with<br />
obvious dominance. Furthermore, the causal source of the panzootic in Anhui was shown to<br />
be polyphyletic. The populations were homogenized into homogenous subunits for<br />
investigation of genetic structure by inter-simple sequence repeat (ISSR) markers. Variance<br />
was greater than 70%, largely due to genetic differences within populations and<br />
subpopulations. Genetic distances and genetic differentiation were negatively associated<br />
with geographic distances and it was speculated that this was due to the effects of<br />
monsoons and topography. Mantid isolates were divided into five pathotypes based on a<br />
two-way cluster analysis of genetic distance. Pathotype I consisted of the predominant<br />
subpopulations of Huangcangyu and Chashui populations, with a genetic distance of 0.120<br />
and gene flow up to 1.833. This pathotype caused a widespread epizootic in north and<br />
southwest Anhui, and Pathotype III caused enzootic at Site A in September and then<br />
epizootic in October, while the other three pathotypes caused enzootics at all three<br />
investigation sites. The widespread epizootics and isolated enzootics composed the<br />
polyphyletic panzootic in Anhui. A strong gene flow between isolates from the two mantid<br />
species was identified, resulting in negligible gene differentiation. This indicated a lack of<br />
host specificity in mantid isolates of B. bassiana.<br />

Sexually Cannibalistic Mantid: Fecundity, Cannibalism, and Male Response in<br />
Stagmo<strong>mantis</strong> limbata (Mantodea). Ecological Entomology, 2010, 35 (6): 775-787.<br />
Abstract: 1. Female feeding regime exhibited a cascade of effects on reproductive biology<br />
and behaviour in the mantid Stagmo<strong>mantis</strong> limbata (Hahn). 2. Well-fed females (High diet)<br />
consistently attained greater body mass, thicker abdomens, and higher fecundity than foodlimited<br />
females (Low diet) in four annual generations. Dorso-ventral abdominal thickness<br />
strongly correlated with fecundity. 3. In an experiment in captivity, Low diet females were<br />
more likely to cannibalize males than High diet females. 4. High diet females attracted more<br />
males than Low diet females in several contexts. In terms of long-range attraction, caged<br />
High diet females attracted more males in the field. In terms of short-range attraction, males<br />
preferentially mounted and copulated with High diet females in captive paired choice trials. In<br />
naturally-occurring pairs in the field, a preference for females with thick abdomens was<br />
evident. These results point to two possible explanations: male choice for well-fed females<br />
and state-dependent female pheromone emission. 5. Two years of field data indicate<br />
considerable variation in female feeding success, as measured by abdominal thickness.<br />
28<br />

Average feeding success in nature appears to be relatively high, when comparing the rate of<br />
abdominal expansion in the field to captive females maintained on High diets. 6. In the field,<br />
nearly all mounts and copulations occurred in September in both years, when female feeding<br />
success is expected to be high. If mating activity occurs during a window of high female<br />
feeding success, so as to reduce the risk of cannibalism for males, then the female feeding<br />
regime may be implicated in the phenology of mating activity in cannibalistic species.<br />

Abstract: The Mantodea of Egypt were studied by examining and identifying specimens<br />
from four main Egyptian collections and some of those preserved in international museums,<br />
collecting specimens from various parts of the country between July 2007 and April 2010,<br />
and previous Egyptian records. We found 60 species belonging to 21 genera and 4 families.<br />
Eremiaphilidae included 31 species in 2 genera with one new record from Egypt,<br />
Eremiaphila gigas; Empusidae, 7 species in 4 genera; Mantidae, 18 species in 13 genera<br />
with one new species, Elaea solimani; and Tarachodidae, 3 species in 2 genera. We provide<br />
identification keys for Egyptian taxa, data on the material examined, the world distribution,<br />
synonyms and a description of the new species.<br />

Praying Mantid Ciulfina biseriata (Mantodea: Liturgusidae). Journal of Ethology 2011,<br />
29 (1): 47-54. Url: http://dx.doi.org/10.1007/s10164-010-0220-6<br />
Abstract: Tree trunks are spatially separated habitat patches for the tree-running mantid<br />
Ciulfina biseriata (Mantodea: Liturgusidae). This paper investigates how intraspecific<br />
interactions may affect spacing patterns in C. biseriata. Many mantid species inhabit tree<br />
trunk surfaces, but little is known about how they interact with this type of habitat.<br />
Behavioural observations and choice tests investigated the effect of a conspecific on habitat<br />
utilisation. Field surveys were used to investigate patterns of movement in the field. The<br />
decision to inhabit a tree trunk may be affected by the presence of a conspecific. Whereas<br />
adult males seek out females when selecting habitat, females will actively avoid males.<br />
Habitat choice decisions are primarily based on aspects of their mating system rather than<br />
on competition for space or food resources. The behavioural interactions of C. biseriata are<br />
described, including novel observations of same-sex mating behaviour in adult males.<br />

Mantid Populations. Insect Conservation and Diversity, 2011, 4 (2): 107–114.<br />
Abstract: 1. The concept of an 'edge' habitat that is influenced by the biotic and abiotic<br />
characteristics of neighbouring habitats is a broadly applied principle in ecology. 2. Ciulfina<br />
klassi Giglio-Tos (Mantodea: Liturgusidae) inhabit vertical tree trunk surfaces in a restricted<br />
patch of coastal Melaleuca woodlands in the world heritage listed Wet Tropics Region of far<br />
north Queensland, Australia. Preliminary observations suggested that abrupt forest edges<br />
may have a positive effect on population density in the praying <strong>mantis</strong> C. klassi. 3. During<br />
field surveys over a two-year period, mantid densities were found to be higher at forest<br />
edges than forest interiors. 4. Greater sapling recruitment at forest edges may contribute to<br />
this edge effect by providing dense patches of tree trunk habitats. 5. The population<br />
characteristics of C. klassi are also described here in the context of our current<br />
understanding of praying mantid life histories. Aspects of the ecology of this tropical praying<br />

Morphologically Distinct Species of Praying Mantis. Journal of comparative physiology<br />
a-neuroethology sensory neural and behavioral physiology, 2011, 197 (9):877-894<br />
Abstract: We assessed the differences in appetitive responses to visual stimuli by three<br />
species of praying <strong>mantis</strong> (Insecta: Mantodea), Tenodera aridifolia sinensis, Mantis religiosa,<br />
and Cilnia humeralis. Tethered, adult females watched computer generated stimuli<br />
(erratically moving disks or linearly moving rectangles) that varied along predetermined<br />
parameters. Three responses were scored: tracking, approaching, and striking. Threshold<br />
stimulus size (diameter) for tracking and striking at disks ranged from 3.5 deg (C. humeralis)<br />
to 7.8 deg (M. religiosa), and from 3.3 deg (C. humeralis) to 11.7 deg (M. religiosa),<br />
respectively. Unlike the other species which struck at disks as large as 44 deg, T. a. sinensis<br />
displayed a preference for 14 deg disks. Disks moving at 143 deg/s were preferred by all<br />
species. M. religiosa exhibited the most approaching behavior, and with T. a. sinensis<br />
distinguished between rectangular stimuli moving parallel versus perpendicular to their long<br />
axes. C. humeralis did not make this distinction. Stimulus sizes that elicited the target<br />
behaviors were not related to <strong>mantis</strong> size. However, differences in compound eye<br />
morphology may be related to species differences: C. humeralis' eyes are farthest apart, and<br />
it has an apparently narrower binocular visual field which may affect retinal inputs to<br />
movement-sensitive visual interneurons.<br />

Abstract: The endemic Malagasy praying <strong>mantis</strong> genus Platycalymma Westwood, 1889, is<br />
taxonomically treated with a re-description of the genus and of the type species, P. latipennis<br />
Westwood, 1889. The genus Ichro<strong>mantis</strong> Paulian, 1957, is newly determined as a junior<br />
synonym to Platycalymma, which results in the inclusion of two additional species within the<br />
genus, P. befasica (Paulian, 1957) and P. dichroica (Paulian, 1957), both re-described within<br />
this study. In addition, we add three new species to the genus described from Madagascar:<br />
P. annulicornis n. sp., P. mahafalica n. sp. and P. viettei n. sp. A key to the six species in<br />
English and French is provided for increased accessibility to the people of Madagascar.<br />

Description of Three New Species (Mantodea, Iridopterygidae, Tropidomantinae).<br />
Zootaxa, 2011, 2777: 1-24.<br />
Abstract: The praying <strong>mantis</strong> genus Hyalo<strong>mantis</strong> Giglio-Tos, 1915 (Mantodea,<br />
Iridopterygidae, Tropidomantinae) historically included two species, H. madagascariensis<br />
Saussure, 1870 and H. punctata Giglio-Tos, 1915. However, we found that H. punctata is a<br />
junior synonym through investigation of the original descriptions and specimen comparisons.<br />
We have redescribed H. madagascariensis to encompass variability of color patterns that<br />
may have led to the description of H. punctata. The taxonomic history for the genus and<br />
species is outlined partly to resolve under Article 33.3.1 of the Code (ICZN, 4 th edition) an<br />
incorrect subsequent spelling of Miopteryx madagascarensis Saussure, 1870 that is in<br />
prevailing use. In addition, we add three new species to the genus described from<br />
Madagascar: H. antsingica n. sp., H. murzini n. sp., and H. whitingi n. sp. A key to the four<br />
species in English and French is provided for increase accessibility to the people of<br />
Madagascar. Illustrations of major features used to diagnose species are provided including<br />
the head, pronotum, and male genitalia. Species distribution is presented and locality<br />

Variation in Polyandry Among Praying Mantids (Mantodea: Ciulfina). Journal of<br />
Zoology, 2011, 284: 40–45.<br />
Abstract: Estimating paternity patterns provides insights into the importance of competing<br />
evolutionary forces on mating systems. The number of sires contributing to a female's<br />
offspring is mostly influenced by her relative promiscuity. However, in a postcopulatory<br />
context, it will also be affected by sperm competition and cryptic female choice. Here, we<br />
describe the paternity patterns of two species of praying <strong>mantis</strong> from the genus Ciulfina, the<br />
agile praying mantid. This study is the first to describe patterns of paternity in the Mantodea.<br />
We found a variation in paternity in these two closely related species. Ciulfina rentzi<br />
exhibited single paternity, with a single male siring all offspring within a clutch. By contrast,<br />
Ciulfina klassi displayed multiple paternity, with the minimum number of fathers contributing<br />
to a clutch ranging from one to four. Differences in copulation duration and reproductive<br />
output between these two species may help to explain these paternity patterns.<br />

Praying Mantids (Insecta: Mantodea) from Goa, India, With New Distribution Records.<br />
Journal of Threatened Taxa, 2010, 2 (12): 1325-1329.<br />
Abstract: Mantid fauna of southern India is very rich. Out of the 162 species of mantids<br />
under 68 genera reported from India, 45 species under 35 genera are known from southern<br />
India (Mukherjee et al. 1995). Only one species was reported from Goa, which is one of the<br />
smallest states of India located in the western coast. Serious attempts for field surveys and<br />
collection of mantids have ever been carried in the region. The present paper is based on<br />
some mantid species from Goa collected during a field survey conducted during the months<br />
of September October 2008. A total of six species of mantids under six genera are collected<br />
and reported for the first time from Goa, India.<br />

Multiple Paternity within Field-Collected Egg Cases of the Praying Mantid Tenodera<br />
aridifolia. Annals of the Entomological Society of America, 2011, 104 (2): 348-352<br />
Abstract: We developed microsatellite loci to examine the occurrence of multiple paternity in<br />
the praying mantid Tenodera aridifolia Stoll, as inferred from the genotypes of the progeny<br />
within field-collected oothecae (egg cases). The microsatellite locus MTA, developed from<br />
field-caught mantids, was found to have three alleles (A, B, and C) among >600 hatchlings<br />
from 18 oothecae from two locations in Japan. Of the 18 oothecae, two show clear evidence<br />
of multiple sires, two show equivocal evidence of multiple sires, and the remaining 14 do not<br />
show evidence of multiple sires. Thirteen of the latter 14 oothecae are exclusively<br />
homozygous, with all progeny being of the same genotype (BB). Although the exclusively<br />
homozygous oothecae suggest a high incidence of monogamy in these field populations, we<br />
caution that we probably underestimated the incidence of multiple paternity, given our use of<br />
one locus with three alleles. This study is the first genetic investigation of field-collected<br />
progeny of a sexually cannibalistic species, as well as the first demonstration of multiple<br />
paternity in nature for a sexually cannibalistic species.<br />

Arthropod Structure and Development, 2012, 41 (1): 87-100<br />
Abstract: External and internal head structures of the mantodean Hymenopus coronatus are<br />
examined and described in detail. The results are elaborately compared with the literature.<br />
Strong crests on the anterior tentorial arms that articulate with the subantennal suture, a<br />
parietal suture and glossae and paraglossae with anteriorly bent tips are proposed as new<br />
potential apomorphies for Mantodea while a head capsule being wider than long, enlarged<br />
compound eyes, the presence of a frontal shield or scutellum, lateral lobes in the anterior<br />
tentorial arms, the presence of a transverse and an interantennal suture and the reduction of<br />
the mentum are confirmed as apomorphies, As potential apomorphies for Dictyoptera the<br />
reduction of Musculus tentoriobuccalis lateralis (M. 49) is newly presented and a “perforate”<br />
tentorium, lacinial incisivi that are located in a galeal pouch and the presence of a postmola<br />
are confirmed. The present study shows the value of cephalic morphology for phylogenetic<br />
analysis but also points out that further studies including evolutionary key taxa are essential<br />
for resolving the evolutionary adaptations among dictyopterans.<br />

During Orienting Behaviour in the Praying Mantis Tenodera aridifolia. Journal of Insect<br />
Physiology, 2011, 57 (7): 1010-1016<br />
Abstract: The visual orienting behaviour towards prey in the free-moving <strong>mantis</strong> was<br />
investigated with a highspeed camera. The orienting behaviour consisted of head, prothorax,<br />
and abdomen rotations. Coordinated movements of these body parts in the horizontal plane<br />
were analysed frame-by-frame. Rotations of these body parts were initiated with no or slight<br />

Mantis-associated Daldinia eschscholzii. Journal of the American Chemical Society,<br />
2011, 133 (15): 5931-5940<br />
Abstract: Polyketides with unknown architectures are highly desired for the discovery of<br />
new drugs and agrochemicals. Here, the <strong>mantis</strong>-associated Daldinia eschscholzii, a fungus<br />
known to produce immunosuppressants dalesconols A and B, was found to simultaneously<br />
generate four novel skeletons capable of shaping the unusual chemistry of the fungal<br />
polyketides, of which seven were structurally unique and substantially immunosuppressive.<br />
In particular, the scaled-up fermentation of the microbe enabled the structural<br />
characterization of minor or "transitional" intermediate polyketides that allowed the<br />
reasonable recognition of the four biosynthetic pathways initiated by condensations of four,<br />
five, six and eight acetate units, respectively. Furthermore, the decarbonylation reaction of<br />
triketone, as in the case of daeschol A, was described for the first time, in addition to the<br />
structural correction of sporothrin C and nodulone. The work provided a set of novel<br />
immunosuppressive molecules that are of significance to drug discovery.<br />
