Woolly Aphid

Commonly found on the leaves, branches, and roots of host trees and shrubs such as apple, alder, and beech.

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

They produce a white, waxy, cotton-like covering for protection against predators and desiccation. They are often found in large, stationary clusters and can be wind-dispersed.

Risks: Can cause plant stress, leaf curling, and branch galls; they secrete honeydew which promotes sooty mold. Benefits: Serve as a food source for beneficial predators like lacewings and hoverfly larvae.
