I cut open the top of this larva's case and spread it out so you can see what the inside looks like. It's a tough coating of silk, surprisingly thick.

Look closely at these pictures of the case and you can see it's not solid wood pieces, but that some of the silk used to attach the wood is showing through in the cracks.

Find a used copy of Wiggin's "trichoptera larvae of north america" or some similar title. It is the best guide to get to genus for all the caddis you may run across

Based on the case and the size, I'd tenatively guess Pycnopsyche. But someone else may have a way to key the larva.
