No, this is
atra:
Is yours perhaps a
Phania? How large is it?

Oops, ok. I have no books or anything to compare with me. The fly is very small, maybe 5mm long. Just a bit larger than
Catharosia pygmaea

Phania ... yes, if I compare the pictures
Phania thoracica would be a very goog choice :)

Just check the dorsal bristles on the hind tibia ...
P.thoracica (lots of apical spurs) is very very rare but
P.funesta (2-3 apical bristles) is very common :)

There are seven bristles (if I can count)

I think only the ones at the distal end count but I have never seen thoracica to check :)

Vibrissae are short, so not
funesta...
P. curvicauda is relatively common in Finland, but it should have darker calypters. I see only two apical bristles on the hind tibiae? Anyways, not bristly enough for thoracica? Would need to take it through the key to be sure. Sorry.

Definitely one for careful keying :)
