Hi, for me it looks like Neomochtherus but maybe it is not ... is it possible to ID? 31052016 Best regards J affiniscyanoviridis attached the following image:  [103.68Kb] Edited by affiniscyanoviridis on 03-11-2016 08:31 |

A female Neoitamus sp. Looks like N. socius or N. cyanurus to me. Knowing the species is rather hopeless from pictures as far as I know. The development of microtrichia on the basal radial cell needs to be seen to separate both species. However, sometimes a well experienced eye might be able to see something helpful. Wait for Reinoud

Actually, it is not so hopeless. You can find very nice pictures of socius here http://waarneming.nl/soort/photos/8202 To me, this looks more like cyanurus. Theo |

Well, Theo, it seems this really needs an expertise eye Certainly, not mine (I still have never seen any of both species in real life) and I wouldn't risk species ID. I only know 'the theory' My idea was that only the microtrichia were diagnostic for females. I truly should keep my mouth shut   |

Piluca is a "wijsneus": ))))) Strictly she is right but a pretty reliable character is the colour of the metatarsi. In this case they seem totally black which would strongly suggest N. cyanurus.
