Wiggling beech blight aphids

Beech blight aphids (Hemiptera: Aphididae: Grylloprociphilus imbricator) can form dense colonies as they feed on the sap of American beech trees (Fagus grandifolia, Fagaceae). The white fluffy bits aren’t parts of the aphids themselves, but instead are feathery, waxy secretions they make. The aphids shake their abdomens to wave these tufts when they’re disturbed, and lightly blowing on them is enough to set them off. This behavior serves as a warning to predators since these insects are capable of stinging in self-defense. Recorded 09/28/2013 at Waterloo State Recreation Area near Chelsea, Michigan.
