Prociphilus tessellatus

Woolly Alder Aphids

Woolly Alder Aphids (Prociphilus tessellatus, family Aphididae) produce large, white fluffy colonies on the branches of their namesake host (Alnus spp.). Their appearance has been variously described as looking like white pom-poms, cotton candy, or white hair covering alder branches.
