Hi, in a sample from a mountain brook I found this realy small, probably first instar larva. Some 1 mm long. Maybe it is coleoptera, Scirtidae, because I already found a late instar Scirtid larva there and it also had a log antenna...

Scirtidae indeed, and if it is found in a brook then it is most likely Elodes, a common representative in running waters. In the last instar (of Elodes) the thorax is distinctly broader than the abdomen.

Thank You, I googled to Elodes and my late instar larva seems to be this.
