hi flyforum,

Looking at my screen, some black point was running on it.
A grey-ish little fly of 5/6mm with some yelloworange abdomen.
The second and third femur(braun) and halters are also yellow, so is the face, that's typical
Looking at my pictures I see no interfrontal bristles and wingvein M1 is quite straight.
I looked at the vein A2, if this vein is curved more or less but that is not simple.
It seems that vein A2 is curved and is crossing imaginary the analvein.

That meant that this fly is a Fanniidae sp.
I am wondering if this is correct, I don't have experience with this kind of flies.

Hi Robert.
A2 curved, but A1 long.
It is Pegomya, Anthomyiidae. Even with your good images species level isn't possible, at least for me.

Thanks Nikita,

But.., Anthomyiidae got Interfrontal bristles? and I can not see any of these..?
That's why I thought it was not Anthomyiidae.

Perhabs there are also Anthomyiidae without these kind of bristles?

are there Anthomyiidae without interfrontal bristles?

just curious to know

Hi Robert.
Unfortunely this damned Diptera aren't easy:
A lot of Muscidae have if - almost all Azeliini or some Phaonia, for example...
A lot of Anthomyiidae havn't -
Interfrontalia without trace of cruciate setae or setulae - Pegomya (M.Ackland)
Only one firm rule - no Fanniidae have if
