Found yesterday in Meppel (Netherlands) sice 7,2 mm
At first I thought is was a Phaonia, but no species fit.
Hydrotaea could also....(H.albipuncta) but then my fly is to long....
I don't see it anymore, whit this fly....:o

There are strong proclinate setae on frons, so not a Phaoniinae. Hydrotaea dentipes is an interesting proposition, however from this picture, it is difficult to confirm (need to see the frontal triangle, here the M1+2 seems not conspicuously bent like H. dentipes...).

Maybe not the best photo (triangle is very shiny in real)
And H.dentipes has black halteres ....mine not..

On the contrary, the halteres appear dark brown, not pale/yellow. If there is an ad on t2 and if apical section of M1+2 slightly bent forward, I think we can do a
H. dentipes of this fly.

R4-5 seams slightly narrowed towards apex...
mt2 has a pd, but on one tibia there are 2 seta above the pd and the other tibia has one seta above the pd.....?
And the beginning of the haltera is yellow and the end is black.
But I don't want to make it to difficult....so I think H.dentipes.....it must be!!
Thanks for the effort ;)
