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] Dmitry Gavryushin attached the following image:  [104.54Kb] Edited by Dmitry Gavryushin on 21-09-2006 07:32 |

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. |
