30 sept, Moscow region.
First one looks like new family for me, Sciaridae: ant - 16, wings longer abdomen, costa ending on wing top, venation on forepart of wing more visible, one only cross vein (Rs by Bey-Bienko, r-m (?) by Menzel).
Second - Ceratopogonidae, short forelegs, ant -7.
Am I right?

Hi Nikita,

I have my doubt about the identification of the second one, but the first one is indeed a Sciaridae!

The second is Chironomidae, possibly one of the species with terrestrial larvae.

Thank you Jan and Paul.
I excluded Chironomidae because of nonplumose antenae...

Usually it is the males who have plumose antennae. Especially in the ones with terrestrial larvae, the male antennae may be less densly plumose.
