Hello!
Here two Muscids (size of a normal house fly) from yesterday night at our house (Ostwestfalen/Germany). The one on pics 1+2 should belong to genus
Phaonia (?). Is the one on pic 3 a
Polietes? Thanks in advance!

What about
Muscina for your 3rd image? I don't think
Polietes has that orange tip to the scutellum, and
Muscina spp do.

That was my first guess, too. But when looking at the gallery, I found that this genus has a rather Calliphoridae-like bend in its wing venation:

I thought the M vein wasn't bent enough too, but then I saw Jan's new picture of
Muscina stabulans in the gallery and wondered...maybe they vary a bit or maybe the angle of the shot is important in how you see the vein.

Ah, thanks! I did not see the newer pics, yet, only had a look at the
M. prolapsa photos. The vein in
stabulans seems to be much less bent than in
prolapsa, but still more than in my specimen. Unfortunately I don't know the other two
Muscina species here in Germany (
levida and
pascuorum, according to "Entomofauna germanica").

See my thread from a while ago re
Muscina levida - it shows a clearly bent M vein (not helping my theory, but never mind;)). I'll get it into the gallery when I have a moment.

http://www.dipter...post_14363 - quite a gentle bend there.

Thanks a lot! The one in the second thread resembles mine much more with its only slightly bent M vein.
