Life of the Party
These were from Mill Creek (tributary to the Russian River). They're usually found in fast water. They're a free living caddis except in the pupal stage when they construct a ramshackle case of stones, attached to cobbles. They usually range from 12-14 mm in both larval and pupal stages.
