Chimmara sp.

[Mark Melton]

These are common in the Russian River. The most active times are between July and October. The larvae are about 9-10 mm, the pupal cases about 10-12 mm and the pupae about 7-9 mm. They have two kinds of cases, a silken case for the larvae, and a rock case for the pupae.

Great photos! In mid-summer, if dries just ain’t happening for whatever reason, I have cleaned up with a simple creamy-amber caddis nymph.
