Woolly Aphid

Found on various host plants including trees and shrubs such as apple, elm, hawthorn, and beech in temperate regions.

Herbivorous; they pierce plant tissues with their mouthparts to suck out nutrient-rich sap, often from leaves, twigs, or roots.

They produce a white, waxy, cotton-like substance that covers their bodies for protection. Many species have complex life cycles involving migration between different host plants.

Generally not harmful to humans; however, they can be significant garden and agricultural pests, causing leaf curling, galls, and promoting the growth of sooty mold from secreted honeydew.
