bagworm
Silk-cloaked tree pest
A bagworm is a caterpillar that constructs a distinctive protective case around itself from silk and bits of plant material, carrying this bag as it feeds on trees and shrubs.
The larvae of various moth species create these portable shelters, which can severely damage evergreens and ornamental plants when infestations are heavy.
The arborvitae was covered in bagworms by late summer.
