Could this fly be: - Empis tesselata - (Fabricius, 1794) ?

This is a Therevidae for sure.
Looks quite interesting.

Looks like Psilocephala (rustica..?)
Interesting!

As far as I understand it is male.
In this case it realy looks like Psilocephala.
If it is Psilocephala, than clearly separated eyes and visible caracters lead me to Psilocephala fuscipennis.
But available key is Bey-Bienko 1969, they admit that fauna of European Russia Therevidae is far from well known.

Could I ask the questions as:
1. Male?
2. Psilocephala?
3. Rather rustica or fuscipennis?

It looks like Psilocephala. I don't know fuscipennis (it is not a northwest-european species).
So I can only guess... and that is not what will help you. Sorry! Frown
Maybe someone else here?

Thank you Andre, than I put it as Psilocephala sp. till farther information (if any).

According to Kevin Holston, this is a female Cliorismia, very likely the species ardea.

Thank you Martin (and Kevin).
1. To my excuse genus Cliorismia absent in Russian Diptera key. In Soveit Union we knew good enought only Diptera who disturb our way to Communist Future, such as Tabanidae or Simulidae ect. Therevidae did not mind aginst Communism, so was completly overlooked.
2. As for your question about 90% alcohol. Next time I'll put Irwiniella in. Just let me know which else Therevidae or whatever else you need.
