And very siutable name indeed, with this Bombyliidae wings! Nikita Nikita Vikhrev - Zool Museum of Moscow University

Here in Finland we have only the latter. Both species are quite rare in Scandinavia and at least T. angustistriatum seems to be bound to old aspen (Populus tremula) stands. Unfortunately I do not have any idea how to separate these species, I have to ask our local syrphidae gurus for help. It's not a fulltime job for them: T. angustistriatum is very rare in Finland with only 3-4 known recents records. Here the only Temnostoma angustistriatum is my collection.

I can see that in these two individuals the abdominal markings in T. angustistriatum seem to be running more straight but maybe that just is individual variation.

I think we don't need to worry about overcollecting flies yet. Especially in Russia Perhaps at some old-growth forest sites in Western Europe, but not in Russia. Your country may have many collecting fly taxonomists, but I doubt you have the highest number of collectors per sqare kilometer. How many million km? of Russia are there per dipterist to cover? But back to business: I understood that separating the Temnostoma species discussed here may not always be quite as easy as the key claims. There is also a systematic difference between males and females in the colourations, so be careful and compare only males with males and females with females. Kahis

No reason in situation that 1000 person can distinguish it from wasp, and 10 person can ID species. If they want to help fly, they should help park or other lanscape, it is the only sensible way, I think. Nikita Nikita Vikhrev - Zool Museum of Moscow University

Member Location: Posts: 9193 Joined: 24.05.05	Thank you Ben. But in Krivosheina key the difference is in hind tibia. My test it is doubtfull species. It is right t3 (left - all yellow). I think it is T. bonbylans. What do you think? Or show the fly to Krivosheina herself? Nikita Nikita Vikhrev - Zool Museum of Moscow University
