Woolly Aphid

Natural Habitat

Found on various host plants, including trees like elm, ash, apple, and hawthorn, often in temperate regions worldwide.

Diet & Feeding

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

Behavior Patterns

They produce white, waxy filamentous secretions for protection against predators and desiccation. They often form dense colonies and have complex life cycles involving both sexual and asexual reproduction.

Risks & Benefits

They are considered agricultural and garden pests as they can cause leaf curling, stunted growth, and the formation of galls; they also produce honeydew which promotes sooty mold. They have no direct health risk to humans.
