What’s this weird worm? Readers’ nature queries

I came across this worm in my garden. It stayed like this for ages and then suddenly started to unravel into a black, thin, 10cm worm. – Tricha Blackburn, Thurles, Co Tipperary

It's an Australian flatworm, either Caenoplana coerulea, the blue garden flatworm; or C dendyi, Dendy's flatworm. It was introduced into several countries in Europe, including the UK. One was reported to Eye on Nature in 2017 in south Kerry.

I found this rare plant at the coast of south Wexford. Webb's Irish Flora names it as Narcissus biflora. The English name is primrose peerless. – Joe Flynn, Enniscorthy, Co Wexford

The National Biodiversity Data Centre has six reports of biflora, two each in Dublin and Wexford, and one each in Waterford and Cork.
