Reader Tammis Coffin sent in this photo of a somewhat hairy thing tucked into the crevice of a beech tree in western Massachusetts. What is it?
Answer
This is the empty shell of a gypsy moth pupa. As anyone familiar with gypsy moth caterpillars (larvae) knows, they’re quite hairy, and the hairs at the bottom of this pupa case are likely from bits of the larval exoskeleton that got packed down into the bottom of the cocoon.
