Small, 1-1,5mm, Moscow region, 24 sept. My guess that it is Drosophilidae base on two points: 1. Small size, Drosophila-like appearence (short body). 2. There are two visible on photo gap on C

1. I found that same date 24.09. I've got one more images of the same fly. First was near (in 1m) from the pond, second - on the another pond surface plants. 2. I add this more image. 3. Now I still vote for Drosophilloidea, but rather for Ephydridae than Drosophilidae. Ephydridae also has a double break on C. 4. White spot on head give me hope that I can await ID till genus too  .

Hi Nikita, I would go for Ephydridae although I have to admit that I am not sure! Jan Willem |

Ephydridae it is. The arista on the first image is branched, but all branches are on the dorsal side. Together with the given characteristics, it can really only be Ephydridae. Maybe Kahis can give you the genus/species.

It's a Hydrellia. This is a large and difficult genus. The only species I've seen with this combo of characters (matt black frons, silvery face and lunula, blackish body) is H. albilabris, but I don't know if these charaters are enough to confirm the species-level identification.
