Found Netherlands (Giethoorn) on 1 August in wild grassland.

Its seems to be a Anthomyiidae (analvein is reaching wing margin)
But whit a very orange vitta and gena...

Dear Stephane,

Maybe I'm a little pigheaded, but can you confince me....why it is a Anthomyiidae!
I can't let loose the idea that it is a Coenosia ....;)

Oke...almost confinced....but can we say than, that when the anal vein is reaching the wing marging.....it is never a Muscidae....?
Because, I thougt that I have seen some Muscidae whit the anal vein reaching the wing margin, but maybe....again...I need new glasses.B):D

Joke
( why I thougt is was a Coenosia:
shiny black proboscis
one orbital setae
setae on hind tibia)

Coenosia never has anal vein reaching wing margin. afaik

I know that there are just a very few species on Anthoymiidae where anal vein doesn't reach wing margin. Well, I only know one species like that :P

Hi Joke,
this is not a Coenosia because Coenosia have only 1 presutural dc, or if 2 presut dc present (subgenus Dexiopsis) the anterior one doesn't exceed one third of the posterior one. Furthermore, members of the Coenosiini tribe always have 3 katepisternal setae arranged in inverted (almost) equilateral triangle. So not even a Conosiini.
I hope I've convinced you... ;)

I think it is enough to see anal vein in this case. Anthomyiidae. Hence never a muscid-. (well, there are special exceptions):P

Anthomyiidae, probably female Pegomya in the hyoscyami group. See annotated photo
