Hi all!

Without being sure, I would interpret this fly as a Tachina (correction or more exact ID very welcome, of course)... but what does it have in its face? Frown Doesn't look like being normal to me.

Approx. 13-16 mm

Thanks tristram!

So this should mean that the fly is either extremely fresh (to me at least, it doesn't look like that, since the wings are already damaged a bit), or much more likely, that the ptilinum failed to collapse after use, right?

Are there any known pathologic reasons for that, or does it sometimes simply happen accidentally.
Best greetings

It is most likely fairly fresh out of the pupa.

Ok, thanks. So it takes much longer to collapse than I imagined. Never seen this before.
Best greetings
