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 ?
