Woolly Aphid

Typically found on host plants such as apples, ash, beech, and elm trees in gardens, orchards, and woodlands.

Herbivorous; they pierce plant tissues to suck nutrient-rich sap, concentrating on leaves, stems, and roots.

They produce a white, waxy, cotton-like substance for protection against predators and moisture loss. They often form large colonies and may have complex life cycles involving different host plants.

They are considered agricultural pests because their feeding can cause leaf curling, yellowing, and stunted growth. They also secrete honeydew, which leads to sooty mold. They are generally harmless to humans.
