hi flyforum,
This fly was sitting on a blackberry in the edge of the forest.
I think Musciade (female) and with these strong fuscated crossveins Phaonia?
other features:
- plumose arista
- hair on eyes
- orange/golden anterior spiracle
- posterior setae
- apical bristles on tibia II are heavy
- 1 prescutellar ac (two hairs, so is this notation of 1 prescutellar correct? > 1 pair of prescutellar ac)
- no interfrontals
- no colouring on the end of it's scutellum.
- size ~ 10mm
0bvious is the yellow/orange couloured stroke of hairs on the backside of the tibia and beneath the apical bristles?
If wanted, I can crop some parts for more detail.

I think
Helina too.
Helina evecta would be a good candidate. Could I have a good view of leg 3, just to be sure ?

Thanks you Joke and Stephane.
What's a good character for Helina sp. ?
I'll give you it's 3rd leg, not 'it's best leg'..
Just look underneath the wing-edge, there you the 3rd leg..

Thanks Robert. I'm convinced that it is
Helina evecta.
- 1 prescutellar ac (two hairs, so is this notation of 1 prescutellar correct? > 1 pair of prescutellar ac)
Correct, scutum bristles are always taken by pair for notation.
What's a good character for Helina sp. ?
Not an easy question. If you found a Phaoniinae with no "Phaonia calcar" (pd on apical third of hind tibia) paired dark spots on tergits 3-4 and straight M1+2, there is every chance that you found an
Helina. When the abdomen lacks the Helina spots (like this one), it is more difficult...
