Woolly Aphid

Found on various trees and plants including apple, beech, elm, and hawthorn throughout temperate regions.

Feed on plant sap (phloem) by piercing stems, roots, or leaves with their needle-like mouthparts.

They produce a white waxy secretion that looks like cotton or wool for protection; they often form large colonies and include many wingless individuals with occasional winged generations.

Can be significant garden pests causing galls and leaf curling; they secrete honeydew which promotes sooty mold. However, they are a food source for lacewings and ladybugs.
