19.09.2006, 2 specimens collected at a swamp beyond our town park with a lot of
Carex, Phragmites, Typha, etc. (I sank knee-deep in fetid black slush :(). Size 4mm.
My first guess was a
Sciomyzidae, but I recalled my lapse with
Platycephala in late July and contacted Nikita first who suggested
Chloropidae.
[Subject changed from Chloropidae, Eurina (lurida)? Thanks to Xespok]

What an unusual wedge-shaped head! A wonderful fly.

Wonderful images! Could this perhaps be Trigonometopus within Lauxaniidae?

2 Xespok: I've checked both your gallery and some keys, it seems you're quite right, it's a
Trigonometopus frontalis :)

Usually, Chloropidae are almost bare - just the Oscinellinae have short bristles. The large bristles on this fly say "I'm not a chloropid". ;)

Addition to Tony's statement: The Siphonellopsinae (Chloropidae)
all possess long bristles including several dorsocentrals and orbitals, in Europe genus Apotropina.
