I currently work on the genus Delia and I need help for the identification...It is not easy! Firsly, I look on the differents posts and some of you are very good to identify with a picture. What are the caracteristics that you use for determine the genus Delia? I use Darvas B. and A. Szappanos key, Male and Female morphology of some central european Delia (Anthomyiidae) pest, and the caracteristics are for the genus: A1 extending to the wing margin (ok!), Lower calypter as large as or smaller tha upper one (ok!), The longest hairs on arista are distinctly shorter than the width of first flagellomere (...hum!? It is visible to the naked eyes?!). The plopleuron is bare (ok) and The apical posterobentral seta of the hind tibia is absent or hardly distinguishable from adjacent setulae...(picture please?!) for the male: Parafrontals without orbital setae. Fore Tibia without an anterodorsal seta. The Aedeagus is long and wll sclerotized...So What is your trick? Thanks a lot! I am completly confused  PS:I apologize for my english, it is not my first language!  RSB |
