I’ve tried photographing these guys in the yard a few times but they always seem to be in motion, floating around like so much airborne lint. Yesterday this one individual decided to loll about on one of our blueberry bushes in the woods out back.
Wooly Aphid-a member of the Aphid subfamily Eriosomatinae. Some of these create galls on various woody shrubs. They feed on sap from a variety of plants and exude a waxy coating which gives them this fuzzy appearance.
