Outside, the silken texture of the bag is somewhat concealed with layers of leaf, twig and bark fragments.

Many insects boring or living in the wood of shade trees are the larval or grub stage of beetles.
Most of these pests attack trees or shrubs that are already weakened or injured by transplant shock, drought, flooding, soil fills, mechanical damage, or disease. They are found burrowing or tunneling under the bark of infested trees. Several beetles, such as the elm leaf beetle, imported willow leaf beetle, flea beetle, and Japanese beetle, attack trees and shrubs and cause feeding damage. Damage first appears when the green parts of leaves are removed with just the veins of the leaf tissue remaining. As damage accumulates, dry skeltonized leaves become obvious.
