Hello fly forum,

I photographed some flies again today at Leerdam, Netherlands.
The flies on the first and second photograph are different individuals, but could well be the same species (I think).
The third and fourth photograph show the same (pretty large) fly/individual.

Any suggestions to the identification are welcome!

The second and third photos are a male Calliphora vomitoria - easliy distinguished by the orange postgenal hairs (well shown in the fourth photo - low down behind the head).
The first and second are different species - look at vein M - it has a strong bend in the second photo. This bend, together with the striking markings, suggests Graphomyia (Muscidae). Although it's difficult to see, it looks like the abdomen is fairly short and extensively orange, so the species is probably Graphomyia maculata (male).
I think the first fly is an Anthomyia male - compare it to the lower picture in http://www.dipter...#post_5532
Notice that the face is very "clean", and has contrasting dark shading outside the vibrissa. However the thoracic pattern is a bit different, so I think it's a different species. They are difficult to identify, and usually it requires examination of the genitalia.

It may be even three diffirent family
1. Anthomyiidae/Muscidae
2. Muscidae
3. Calliphoridae

Thank you very much for your help, Tony!
You are right, the flies on the first two pictures are quite different, now I look more closely. The abdomen on the second fly was quite short and orange indeed. The fly on picture nr. 1 I only saw briefly, just long enough to take this picture, so I have no additional info about it.
Anyway, I'm learning a lot about flies and I'm enjoying it.
