Hi,
Recently I came across a swarm of tiny flies that proved to be green Chironomidae. I suppose the females and male I photographed belong to the same species. Is there anything to be said about a taxon? Many thanks, Sundew
These are females:

Maybe
Dicrotendipes? I do not have my Chironomidae books with me. A closer look at the tail might help.

Inferior volsella appears to be agreed with your hypothesis, and there's a kind of spur in the hind tibia. But I'm concerned about antepronotum, that is not really much visible from this photos.

I think
Dicrotendipes is a good guess, comparing the pictures in
http://bugguide.n...860/bgpage. The decisive character of the genus, the bipartite appendices inferiores of the male hypopygium, is more or less recognizable in the left picture. The larvae are said to inhabit littoral sediments of standing (seldom flowing) waters, and this is a perfect description of the state of the Teltow canal, in the close vicinity of which the swarm was seen.
Many thanks to both of you!
