The calypters look too large for Rhinophoridae.

To my knowledge Sarcophagidae always have a sharper bend in vein M, and your fly's arista is bare.

Calliphoridae normally have a plumose arista. There are exceptions in subfamily Melanomyinae, which may also have a gentle bend in vein M. To my knowledge, no Melanomyinae have petiolate cell r5.

Muscidae never have petiolate cell r5.

To run through the Central European key you need the arrangement of the postsutural intra-alars.
