Hello,
I've found that fly at 24.07.2007 in Finnland (Aland-Islands).
Without functionable wings it is major difficulty...
Size like Musca domestica (perhaps it is Musca domestica?) (ca. 8 mm).
Who can help?

This fly has only just emerged from the puparium, and has not yet pumped up it's wings

This fly is emerging. Had you waited another hour, you would have seen the fly pumping haemolymph into its wings thereby expanding it, and than the fly would have flown off.
I can not comment on the species.

It is not
Musca but some other muscoid fly (Muscidae or Anthomyiidae, it is difficult to tell with such a 'newborn' specimen)

Looks like
Pollenia to me (
Calliphoridae). I remember these youngborn crawling about frequently in offices and such...

Perhaps more pictures can help...

The feet are big. Sarcophagidae?

I doubt it is
Pollenia - no pale curly hairs are seen. I suspect crex is right (and thus I am wrong :))

Thanks for explanatory notes and the determination to all of you.
I think Sarcophagidae is a good idea :-)

The red eyes and prominent bristles suggest a sarcophagid. I have heard that some flies can remain teneral for quite a long time - up to 48 hours I think. Can't remember the source for that though.
