Cottonwood Leaf Beetle: Host and Damage
The preferred hosts of cottonwood leaf beetle are cottonwood (Populus deltoides), other poplars, and some species of willow, particularly basket willow (Salix viminalis).
Adults feed on leaf margins and cause shothole damage. Young larvae skeletonize leaves and, as they mature, consume all but the main leaf margins. Severe infestations cause serious defoliation. Defoliation can decrease diameter and height of the trees and increase lateral branching and terminal forking, resulting in decreased biomass available for pulp and bioenergy.
