Likely a female Forcipomyia, but not sure. I found it dead, wing width is only 0.61mm, so very small. Are there maybe keys with wing pictures? Netherlands.

I agree with Forcipomyia. I can not help with species ID.

Wing patterns in Forcipomyia are rarely distinctive. Most species have uniformly colored wings or a pale spot at the tip of R1.

OK, thanks. Maybe wing width/length could help to exclude some species, but not all.

The ratio of lengths of the first two tarsomeres of the hind leg is helpful in distinguishing subgenera. The first tarsomere tends to be shorter in subgenus Forcipomyia than in other subgenera.

I don't think that is visible in this picture...

Probably subgenus Forcipomyia.
