Woolly Aphid

Found on the leaves, branches, and roots of various trees and shrubs including apple, elm, hawthorn, and beech trees.

They feed on plant sap using piercing-sucking mouthparts, often targeting the phloem of host plants.

They produce a white, waxy, cotton-like covering for protection against predators and desiccation. They are known for complex life cycles involving alternating host plants and both sexual and asexual reproduction.

They are considered garden and agricultural pests as they can cause leaf curling, galls, and weaken trees; however, they serve as a food source for beneficial insects like ladybugs and lacewings.
