Life Cycle
Eggs are laid in flattened masses on the bark or masses that encircle small twigs. Egg masses range from 100-400 with the average size being 150-250. Eggs are held in place with a frothy substance called spumaline. Most species will cover their eggs with this. Hatching occurs in the spring. Young larvae eat the egg shells then the buds, then young leaves.(2)
Larvae have 5-6 instars(2)
When ready to pupate they spin cocoons that are about 1" long, fairly loosely constructed and white or yellow because of a powdery material dispersed between strands of silk. Cocoons can be found in old tents, inside logs, under loose bark, and between folded leaves.(2)
