hello everybody,
I'm interested in insects but I'm an amateur:|.
So, I would be happy if someone could help me identifying the following fly which I saw last week on an excursion near Frankfurt.
There were a lot of flies - including Calliphora ssp. - on a dunghill.
See picture 1:
I want to know the yellow one you can see a little closer in the following picture:

Especial the spotted wings and the yellow abdomen I can not find in any book.
Here is an link for an additional bigger picture.

Platystomatidae!!! :| I'm referring to those that are black with nice patterns on thwe wings and with swollen abdomen. Platystoma sp.

The others are probably Lucilia sp. IT is need a more detailed view of those green flies.

Wow, you are very fast:D
Now I have a name and can make further investigation.
Thank You

It's far from certain, but I'm thinking Platystoma lugubre
