Pupal "horns" like these, protruding through the puparium integument, are typical of some families in Aschiza (e.g. Phoridae). They also occur in Syrphidae. It would help to know in what habitat and substrate the puparium was found, and how big it is, but I'd say this was a hoverfly puparium.

This has all the makings of a phorid puparium.

Thank you Paul and Tony!

A friend found it under a stone with ants...
The pupa is about 1cm big.
Hopefully it will hatch soon!

I'm not sure, but what about the pupa of Volucella?

Hi Atylotus!

Yes, you are right - and Tony was thinking about Volucella too.

Indeed, it hatched today.. :D

I think Volucella zonaria. (see picture below)

Thank you all!

that's GREAT !
the size and syrphid like appearance made me guess Volucella. I'm not an expert on adults, so try to post the photo on the syrphidae forum. I think the fly has still a bit soft skin.
