Hello!

Another fly which I am not sure about its family - Tachnidae or Calliphoridae? Photo taken on May 5 here in Germany. It was a rather large fly, bigger than Calliphoria.

This one is easier: the eyes are hairy and the arista is bare: therefore it is a Tachinid.
It looks rather like a Calliphorid given the narrow vertex and bulky appearence. This suggests the genus Ernestia. The crossed apical setae on the scutellum then fix the species:
Ernestia rudis


A common spring species (may) in coniferous forests.
(Host: Panolis)

Thanks a lot! Ernestia was my closest guess, too. But I was not sure because we have only a few coniferous trees here between mainly beeches and oaks. Nevertheless these flies are rather abunbant in spring.
