Hello,
several of these tiny (2 mm) Psychodids I find at the bathroom sink since a week or two(northwest Germany).

I don't know. It has the wings folded, so it should be a Psychoda spec. But they are anything between white and grey, not blackish. Try to make more pictures. And when you find a dead one, look at the last segments of the antennae under a miscroscope.

Hello weia,
thank you for your reply.

I know the "normal"
Psychodas, but this is not a single case. There are several of them, all completely black. I have also seen a mating couple.
Try to make more pictures.
I will try, but I doubt, that I will get much better photos. They are so small...

I can only try a magnifying glass, I don't own a microscope.

Hello,
I have just tried to shoot a better pic of an antenna.

You come quite far with the antenna. I have only knowledge of the species of the Netherlands and Belgium, so with some reserve: it looks like subspecies Psychoda, which in my region contains 3 species. It looks much like Psychoda (Psychoda) crassipennis, but I have never seen one in a collection, so I don't know its colour.
Crassipennis means 'thick wing'

Did you watch the mating behaviour? Before and how they find each other, duration?

I only saw one couple already together, abdomen to abdomen. They sat there at the wall quite a while.
