Boundary Waters 'Wooly Aphid'

This little flying aphid, approximately 0.5cm length, was hatching as we were fishing near the Canadian border. It looked like a little bit of fluffy cotton floating in the air. Taxonomy is as follows, but I have not identified the species:

Order Hemiptera - True Bugs, Cicadas, Hoppers, Aphids and Allies Suborder Sternorrhyncha - Plant-parasitic Hemipterans Superfamily Aphidoidea Family Aphididae - Aphids Genus Eriosoma - Woolly Aphids
