I previously posted these photos of the larva within its leaf tunnel, sandwiched between two circular discs of leaf:

Further clearance of debris from the bottom of the pond found many leaves with discs cut from them. I found several more of these larval shelters, some empty, some occupied, which seem to be on the bottom of the pond and not with an air pocket in the central tunnel to help them float around. Any ideas which caddis this is?
