Moscow, 13may, 6mm.
Alas, did not collected.
But colour isn't very usual for Muscidae.
May be Phaonia rufiventris?

Nikita My rufiventris all have orange humeri and yellow fore-femora. This may well be bitincta.Can you see very long aristal hairs and 2 pairs of strong presutural acrostichal bristles on your high resolution photo? It fits in all other respects to judge from the description I have - but like you no specimen:( May I send your pic to Adrian Pont? Rain in Ireland today:( Robert

Thank you Robert.
Unfortunely photo isn't as good I wish. This fly dislike flash and move every time.
I excluded Ph. bitincta for two reasons:
- all grey scutellum
- bare arista. I think it is visible on large photo I'm adding now.
It seems to me that presutural ac - 2, but not as stong as dc, for example.
Nikita
P.S. Of course, you can show this photo.

Nikita We were both wrong. Here is Adrian's reply:p "Take a look at the hind tibia. Two anterodorsals and two posterodorsals do not occur in combination like that in muscids, and this looks for all the world like a Pegomya. With the rather cylindrical abdomen and prominent sternite 5, I would say Pegomya bicolor Wd." This is extremely useful since it is so difficult to get this kind of information and Adrian is, as you prbably know, a world authority. Despite the slightly fuzzy picture perhaps Paul would put this one in the gallery since reliably identified (in nature) Anthomyiidae pics are not so common. More Muscidae please (please, please) especially with specimens. I'll try too but only with museum specimens.Robert

Everyone. So it wasn't bitincta and it wasn't rufiventris. These were the only flies that keyed out so we made our answers fit. The answer it wasn't a Phaonia or even a muscid. I really should listen to my own advice.Did someone say someting about hindsight? Mortified :(:(
Robert Suns out though.:p

Thank you Robert and special thanks to Adrian Pont (I've heared a lot of good words about him from Andrey Ozerov).
Realy, Anthomyiidae is even better answer.
