These are relatively common in Mill Creek, a tributary of the Russian River.
They're found in pools on the side and top of rocks. They use a net to capture diatoms and algae. The net sits flat on the rock usually over a small declivity.

When ready to pupate, the larva leaves the net and finds a large rock, spins a covering of silk and sand and begins pupation. Pupae are usually found on the top or side of a rock.

Nice pics - especially pupal stuff - can you get a close up of the head showing the structure (bump) between the antennae? Does that hang over the front of the head like a ball-cap brim?

Kind of pressed for time right now. Will try to get pics of the head later.
Did take a look under the microscope and it does to appear hang over the front of the head.
