Dear Diptera-community,
this larva has been found on a 2 weeks old piece of cowmeat in the Upper Saltmarsh on Spiekeroog Island in September 2015. Do you have any ID?
Thanks for your effort and cheers,
Hagen

Can you photograph the hind spiracles?
In North America the most common large maggots in carrion are Sarcophagidae and Calliphoridae. They are distinguished by this key couplet:
Posterior spiracles in a deep spiracular cavity (Fig. 84); spiracular openings inclined more or less vertically; ecdysial scar usually not visible; peritreme incompletely encircling spiracular plate... Sarcophagidae
Posterior spiracles exposed at apex of terminal abdominal segment (Fig. 82); spiracular openings obliquely inclined; ecdysial scar present; peritreme completely encircling spiracular plate... Calliphoridae
See
Manual of Nearctic Diptera volume 1 chapter 5 page 144.

Dear John,
normally, Calliphoridae and Sarcophagidae are the usual suspects - so far so good. But I had a lot of other strange fliy larvae inside (like Fannia spec. and others).
Because of the neccessary resolution, pics had been uploaded here:
