Woolly Aphid

Found on various host plants, including trees such as elm, apple, and ash, often in temperate regions.

Plant sap (phloem), extracted using piercing-sucking mouthparts.

They produce a waxy, white, cottony covering for protection and may perform 'dances' (synchronous swaying) when threatened. Some species alternate between host plants throughout their life cycle.

Generally harmless to humans, but can be a garden pest that causes leaf curling or gall formation. They produce honeydew, which can lead to sooty mold growth on plants.
