Hello flyforum,

I did not think about Muscidae when I saw these flies on bark.
The size was more then 10 mm, rather big for Muscidae.. I think.
But the wingpattern is all Muscidae.

A dark(black) fly with some colour; - a bit grey-blue and the eyes redbraun -
The end of the scutellum is orange.
The Abdomen is white banded and the bottom gots long hair.

place: Amsterdam forest

Well, apex of scutellum - red, M1 - stright (almost), large. To my limited knowledge - some Phaonia.
But, I didn't find siutable Phaonia species for this image...

I think it might be Muscina prolapsa. I know there isn't much of a bend in M, but there is a bit, and it seems to me that Muscina display quite a variation in the amount that vein bends. It's got the orange scutellum tip, and orange mouthparts which fit, but I would also expect to see some orange on the antennae but it is not always obvious in photos.

I've never seen Muscina with such M1.
But it seems that Susan is right...

Thank you all for the information and search for specie.

When I look at the head, I see some coloured parts (looks orange..)on the base of the antenne.
The arista is plumosa, there is hair on the eyes.

I think M1 is a bit curved.. and Muscina is a good option (with orange tip on scutellum)

Muscina prolapsa was my first thought too, although vein M1 is rather strange, almost straight. Compare it, for instance, with this fly of mine: http://www.dipter...post_22087, also (presumed) M. prolapsa.
I still wonder about M. pascuorum, a species of which I can find little information, and how to seperate it from prolapsa.
But look at this thread: http://www.dipter...post_18551, with a fly of which Tony suggests it might be pascuorum, it also has quite a straight M1.
