Hi, I've found this copulating couple (~3 mm) on a wall 20200531 and I am not able to identify even the family. Chamaemyidae? Milichiidae?
White: wings, genae, several rings on tibiae and tarsi.
Black stripes on the head.
Red stripe on the eyes.
Unfortunately this is the only usable photo.

Does anyone know these flies?

Thanks a lot in advance!

Eric
