Female of Fannia. Yellow tibiae may help. Which data? Autumn?

Well, in late autumn females of F. pruinosa/pallitibia are very common in Europe. Both species have yellowish tibiae exactly as your female.

Thank you very much, Nikita, for your time and your ID :)

I'll watch this tandem carefully.

As for me, I suspect that pruinosa and pallitibia are the same.

Hello Nikita

Like you, Adrian C. PONT ("A Revision of the Fanniidae and Muscidae described by J. W. MEIGEN") cannot separate the females of these "two species".

For the males ("key to males of European species of Fannia"), Barták & al. considers two species with very tiny differences. He don't say that males of F. pruinosa have setose parafacials, like I read in this post. So, I don't found a picture of these setae ...

I note the probable confusion of the two species

Thank you, have a good day
Patrick

PS Sorry for my english
