Woolly Aphid

Found globally on various host plants including ash, maple, apple, and beech trees, particularly on the undersides of leaves or on stems.

Honeydew-producing herbivores; they use piercing-sucking mouthparts to feed on plant sap from leaves, buds, and roots.

They secrete a white, waxy, cotton-like substance for protection against predators and desiccation. They are known for a 'dancing' rhythmic movement when disturbed.

Generally harmless to humans. They can be agricultural pests by causing leaf curling or galls on plants, but they also serve as a food source for beneficial insects like ladybugs and lacewings.
