Silkmoth c-section

All of my silkworm cocoons hatched except 2. One of them was wiggling a lot yesterday, or was it the day before? Finally last night, I began to see the telltale staining as the moth applied its secretions to open one end of the cocoon. Many hours passed, and the moth never emerged. The stained area was almost dry. It seemed the moth might be trapped in there. I decided to open the cocoon.
