I wonder would it be possible to tell something about the fly on the image like that (sorry). I saw these flies (quite a few) on the trail in a forest-park of Moscow (Russia) on the December 19, 2011. The size of the fly was roughly 4 mm long. They were sitting on the freshly fallen snow, never flying (like winter crane flies that I also saw these) but when approached they rather tried to escape by running on the surface of the snow. Could it be something like Limosina silvatica? Thank you. Amara attached the following image:  [45.72Kb] Edited by Amara on 21-12-2011 17:15 |

Yes, Sphaeroceridae, possibly a Crumomyia. One of the species in that genus is C. pedestris, 'the walking Crumomyia'.

I am back to this thread with the pictures of the same or similar species. This is the most dominant fly here in a Moscow (Russia) park, where they are hovering over any piece of water (streams, small ponds, puddles or even wet soil) mating. Would it be possible to confirm their id? Amara attached the following image:  [135.75Kb] Edited by Amara on 16-05-2013 07:06 |

The new fly is a Hilara and would like to eat your old fly. |

Hilara is an Empididae fly. It does not belong to the Sphaeroceridae family.
