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.
