Found in a container with Lepidoptera pupae, but I'm ignorant what was the host :(. Size 10 mm. Prosternum a bit deformed, although I remember I handled it with enough care...

A dorsal view + the head.

Nilea hortulana perhaps? :)

Thanks Chris - maybe I'll have some time and try to key it myself before Theo strikes :) (but it's much easier to key a new Platypezidae...)

Chris, excellent call !
I puzzled me.
You can see the characteristic fringe of bristles on the tibia 3 nicely in the first picture.
Black: this means the host was some Noctuidae, probably Acronicta.
Does that ring a bell ?

Wohoo! I seem to be on a roll recently! ;)

Actually, I hadn't noticed the fringe of bristles on the hind tibia before you pointed it out Theo - I don't see many Nilea here. :( It's not 100% clear inthe photo but is it identical to the Sturmia bristle-comb?

It's quite like Sturmia, slightly less pronounced though, especially in some females. Nilea is easier reared than caught in the field, which supports your ID.

Oh, many thanks Theo and Chris. There's a number of Acronicta pupae so this fits OK (only one A. megacephala has hatched recently, there's also some A. alni and A. aceris).
