May 16, 2015, Naro-Fominsk, Moscow region, Russia. Two days of heavy raining and pretty cool, so I keep searching the walls of my balcony. Wing length 2.5 mm.

In the Harnischia genus group, maybe a Cladopelma or Cryptochironomus.

Many thanks John - it seems that male genitalia don't readily provide a good clue for these critters - not too encouraging... |

Male genitalia are very important and this should be identifiable to species, but I lack experience interpreting the subtle differences in this group. It does not clearly match any of the illustrations I have. |

What about Parachironomus arcuatus? |

Thanks a lot to both of you. Here's images from Lehmann, 1970 (Hydrobiologia, 33 (1):129-158). As for the type of colouration, I believe my specimen is No. 3 (bottom right).

Color is influenced by water temperature. If this is a multivoltine species, the spring generation should be darker. |

And Cladopelma 's one shouldn't have less constant width? Why not Cryptotendipes sp.? volsella, anal point and gonostyle appear quite matching to me. I'm just speculating, so I'm ready to change mind  |
