I can't help you with the id., but you could pick the coccoons and put them in a jar with a screen lid and a few slightly damp leaves and see what hatches out. Adults are usually easier to get identified than larvae are.

The other day as I was pruning one of my young apple trees, I pulled on what I thought was just a withered leaf. It was attached to the branch by two white filaments, which I immediately thought were insect-made. As I examined it, I discovered the leaf had been sort of mangled. I grubbed around in it, and inside a tiny stem-like tube was a 1/4 inch long brown worm. Altogether I found about 20 of these on my 8 young apple trees.
Does anyone know what this is? I looked in my pest ID books and wasn't able to find it. What do I do about it?
I live near Atlanta, Georgia, Zone 7 if that helps.
