Moin Ray, I think it's a Tachinida - probably a (teneral?) Macquartia.

Moin and Thanks Eric,
I'll change the title and see if I can get a confirmation of that.

Best Regards
Ray

Thank you Theo,
What feature defines it as being teneral?

In this case it's the swollen frons: Tachinidae belong to the Cyclorrhapha and they escape the puparium with the ptilinum (kind of bubble expanded by haemolymph). The "bubble" shrinks but this process is not completed here.
