Found an unknown pupa of a fly on 14.v.2018 when sweeping with a pondnet in a waterbody named 'De leiding' just west of Witharen (Overijsel), The Netherlands. It wasn't an aquatic fly (I'm an aquatic biologist), nevertheless the shape of the pupa and the peculiar anterior spiracles (with numerous pores) intrigued me, and I tried to rear it. After about a week the adult emerges (somewhere around May 20) and photographed it too.
As I have no idea what family it is and the pupa is unfamiliar to me, I would like it very much if anybody has a clue.
I don't need it, so if you like, I can send it, it is still alive and kicking on my desk. I think I will preserve it in ethanol tomorrow.
On Waarneming.nl Agromyzidae was suggested, but uncertain. The fly is 2.7 mm long. The pupa is probably an accidental catch from vegetation and is terrestrial.
Thanks
