Dear Sara
All the pupa of Nematocera are exarate i.e. the wings, legs and antenna are not fused, but are each within its own sheath and movable. (Cecidomyidae is an exception). In lepidoptera for instance the pupa is obtect i.e. the appendages are fused and not movable and in higher Diptera the pupa are co-arctate i.e. a hardened case without seeing any appendages. I do not know what the Hymenoptera pupa looks like, but I think they can be either exarate or obtect. So My specimen could also be a Hymenoptera, but the habitus reminds me of Diptera.
if you have another definition of exarate/obtect than enlighten me, but in Nematocera pupa the appendages are free.
