RSP Hibernaculum Process
I thought the tiny caterpillar would eat the whole leaf. It started with the very end.
Caterpillar pretending to be waste material. The leaf material under the caterpillar also contains waste.
Shaping Leaf. Leaf is attached to the twig with silk. Most of the leaf is cut off and drops down to the ground. It does not eat the whole leaf. It makes a spoon shaped section and then silks it together to make a small round nest.
Green Leaf Segment, turns Brown to match fall colors. These stay on the twig all winter. In the spring, when the tree leaves begin to grow, the caterpillar emerges and finishes its cycle. These leaf nests are only about 1 and 1/2" long and about 1/4" inch wide.
