Hello!
This one was very small for
Calliphora, not bigger than a house fly. But it had orange cheeks, so
C. vicina? Found yesterday night at our house (Ostwestfalen/Germany). Not visible on the photos, but at some angle the abdomen seemed more greenish than blue.

Hi J?rgen
Your photos show the pale basicosta well, so I think this is certainly
vicina. As with all carrion-feeding species, the amount of larval food determines the size of the adult, so there is a wide range of sizes in
Calliphora. Rognes give the length of
vicina as 5 to 12 mm.

Thanks! It already came into my mind that the small size could be the result of larval foot shortage. But I never saw
such a small
Calliphora (and never such a late one).
