Thanks for all comments.

Found:Germany, Saxonia, Gerichshain near Leipzig, 4. Oct. 2020
Hello,
I was today on this place, where yesterday a friend had have the problem with the invasion of little flys.
What i found you can see at pictures. I think it is Chironomida and not Scatopsidae.

Best regards
Michael

The last photo shows male Orthocladiinae. The photos before show female Orthocladiinae.

I'm puzzled as to why your initial photos show an all-female swarm. I can suggest two possible explanations - one is that this species is parthenogenetic, and males are absent (or very rare) - this would suggest that the males you photographed are a different species. Or that the initial photo shows a mixed swarm of males and females - some species of chironomid (e.g. Corynoneura have males that look very like females (short antennae and compact bodies). Again, it would suggest that the later photo is of a different species. Of course, John may have a simpler explanation! :)

Paul suggested Smittia. According to the guide to holarctic Chironomidae, "Smittia is characterized by possessing bare wings and squama, strongly pubescent to hairy eyes and a strong subapical seta on the antenna."
