Woolly Aphid

Found on various host plants, including trees like apple, elm, hawthorn, and alder.

Herbivorous; they use piercing-sucking mouthparts to feed on plant sap from leaves, stems, or roots.

Notable for secreting white, waxy strands that resemble wool or fuzz for protection. Some species alternate between different host plants throughout their life cycle.

Generally not harmful to humans; however, they are agricultural pests that can cause leaf curling, yellowing, and stunted growth in plants. Their sticky honeydew can also promote the growth of sooty mold.
