Cherry Scallop Shell Moth

The larvae of cherry scallop shell moth web leaves together near the ends of branches on black cherry trees and then feed gregariously within the nests.  They add more leaves to the nest as they feed.  Both the larvae and moths are quite striking. The larvae are black with four white stripes on the back, yellow underneath and have orange heads.  The moths emerge in the summer and lay eggs on the leaves of cherry trees.  An egg parasite is reported to keep the population under control in most years.
