See this bug in the Encyclopedia

Natural Habitat

Found on the leaves, branches, twigs, and roots of host trees and shrubs, particularly fruit and ornamental trees.

Diet & Feeding

Herbivorous; they use piercing-sucking mouthparts to feed on plant sap (phloem).

Behavior Patterns

They secrete white, waxy strands that resemble cotton or wool for protection. Some species alternate between different host plants during their life cycle.

Risks & Benefits

Typically more of an aesthetic nuisance than a threat; however, heavy infestations can cause curling leaves, branch dieback, or root galls. They produce sticky honeydew which can lead to sooty mold growth.
