July 21, 2006.
Size 2.5 to 3mm.
This one was kindly identified by Dr. Jindrich Rohacek as a Rachispoda lutosa (Stenhammar, 1855). According to his comment, it's "a common paludicolous species living on mud at water of various kind, also in boggy meadows and other wet habitats".

It is small fly always siting on the silt altogether with Ephydrids like Parydra?
In this case my Sphaeroceridae

is Rachispoda lutosa too?

Nikita, you should ask an expert, moreover, this very depicted specimen is now in your hands ;), yet the habitat where it was collected fits just perfectly (remember that bog with lots of Sciomyzidae? P. glabricula was caught somewhere near, too).

I think yours is too dark and glossy for Rhachispoda. Maybe one of the Leptocera species?

Thank you Paul, but unfortunely I can't share this educated conversation, because I still haven't got Pitkin's Sphaeroceridae key from Royal Entomol Soc:(
