found in invertebrate colonisation trap in a loch, it has small paddles on the ends of the 2nd legs?
No interactions present.
I'm not sure, do adult caddis move their middle legs in a rowing fashion when in water? I'm guess the antennae are just brushed back from the emergence and the wings are still folded away.
Accurate description. Caddis are very interesting in having an active pupa in a thin skin so it is the adult, in the skin that does all the work. The skin is left when they emerge.
