No hairstreak larvae under the bands today, but some of the commonly encountered species are reaching their final instars and starting to pupate. I’ve already seen a few chalky yellow tent caterpillar cocoons stuck between the two flaps of burlap on a number of trees and today I found a pupa of another species.
A last instar American Tent caterpillar (Malacosoma americana).
A tent caterpillar cocoon between two burlap flaps.
A chubby molting Ruby Quaker (Orthosia rubescens).
A large, irritated last instar Ilia underwing (Catocala ilia).
Unknown pupa attached to the burlap.
