Woolly Aphid

Found on various host plants including ash, alder, apple, and beech trees across temperate regions.

They feed on plant sap (phloem) by piercing the host plant's tissues with specialized mouthparts.

They produce a white, waxy, cotton-like excretion for protection. They often cluster in large colonies on stems or leaves and are known for a 'dancing' motion when disturbed.

They can be agricultural pests, causing leaf curling and galls; however, they provide a food source for beneficial insects like ladybugs and lacewings.
