If Lonchopteridae than Lonchoptera. But may be species level is possible? P.S. Just found in Netherlands check list that Lonchopteridae is also "responsibility zone" of Jan Willem. Sure, species level is possible!  Well Jan, I help you a little: o5 okt, Moscow region, size seems to me a little bit more than on Lonchopteras I've seen in August.

Just off-hand it maybe tristis because it is rather dark, but to be safe I must try to run it through a key. There may just be enough visible detail to confirm an identity.

Hi Nikita, I agree with Paul! Given the coloration and your remark about the size, your specimen most probably belongs to Lonchoptera tristis. Jan Willem |

Hi Nikita, There seems to be an anteroventral bristle in the distal half of the middle tibiae (although not clearly visable in your picture). Further it looks similar to Lonchoptera lutea. This combination points to Lonchoptera bifurcata. This is the species of which the males are only rarely found. Your specimen is a female. Jan Willem |
