Hi everyone,

This is only my second thread on your nice forum, that time I need your expertise to identify an aquatic larvae that should be Chaoborus genus. From what I understood we need to observe the labral blade (that is not easy to observe!) but actually that doesn't help me a lot.

I found these larva in a pond in France (Jura), January 19th 2014.

Thanks a lot for your help and comments!

Submitted for the gallery, but as I'm not used to do it I think I didn't submit it into the right place (adult gallery instead of larva, sorry for that).

I finally got pupae, not all survived but 2 females (I think) emerged recently. One of them gave eggs immediately after (what was surprising for me).

Can we confirm definitively that it is C. obscuripes females?
