In windy weather is found under stones and rocks on eastern slopes. Last year I've published the photo of the same species, unfortunately it didn;t give any results. Maybe this one will bring some clearance... Dark ventral side, bluish eyes and bright yellow dorsal side. Males and females have similar coloration.

I am only an amateur and Eastern species are pretty unknown to me. I can try to do some searching in a few days (impossible at this moment). A bit of patience and hopefully I'll tell you something soon Best Piluca Edited by Piluca_Alvarez on 03-04-2017 06:01

Also I've tried to resolve the puzzle by myself, using key from "Parasitic flies of the family Bombyliidae (Diptera) in the fauna of Transcaucasia", (Zaitsev. 1966), I wasn't able to find any description of neither Bombylius, nor Systoechus, reassembling the fly Here's an old pic of the same fly I took last year in February, hope it will be helpful.

And there are also the drawings of female and male. (see attached file). The problem is I don't know whether the species is valid or not.

This is the best suggestion from all! Seems to be true, also the species is present in Georgia and Caucasus as well. Thank you, my friend!
