Food

Life Cycle
Eggs are laid in flat clusters usually on the upper surfaces of the leaves in June or July. First instar larvae feed gregariously on leaf surfaces during July, spinning much silk and webbing the surfaces together. Later they move to the trunk, searching for hibernation sites in rough bark or under moss.(4)
Overwinter as 2nd instars.(4)
In spring, they climb the trees and mine the swelling buds. Later they roll leaves and feed within the enclosures. Pupation occurs within the rolls.(4)
