Cecidomyidae. As far as I can tell there are no aquatic species.

Merci Atylotus

You know that as we have to collect water samples in 8 places if a place in a stream
we need to move and shake aquatic plants, phragmites and bryophits we often find non-aquatic organisms from plant debris such as slugs, ladybugs, a.s.o.
I have been told that they are some CECIDOMYIIDA : PORRICONDYLINAE
living in such as aquatic biocoenosis... (torrential stream France SW)
(http://www.limnol...63p225.pdf )

Regarding the organism found in this pupa, could we ID better ?
Or we have to stop here by lack of features ?
SDS

MAYETIOLIA ?

I can no longer send private messages (and maybe not receive?), even though my inbox and outbox are not yet full. I write, click "send" and they disappear and never show up in the outbox.
