Synonyms and other taxonomic changes

Paraprociphilus tessellatus (Paraprociphilus is now considered a subgenus of Prociphilus)
Gray to black in color. It gets its name from the fluffy, white wax found on its abdomen. Colonies are obvious because of their white, fuzzy appearance.
East of the Mississippi River
Silver maple and alder
Life Cycle
It requires alder and silver maple to complete its life cycle. Occasionally, it is found on red maple.
The aphids on the trees are wingless. They feed on sap from the time of bud-break until late June. Then winged adults, some with abdomens covered in white fluffy wax, are produced in the colonies. These winged migrants readily fly when disturbed. Iowa State University
They are usually seen on leaves, twigs or bark. Although infested leaves shrivel and drop early, the pests cause little permanent damage. As a result of the honeydew, sidewalks and cars become sticky.
They are an important resource for natural biological controls such as lacewings, lady beetles, hover flies, and parasitic wasps. Tolerance of aphid presence is one way to encourage beneficial insects. Iowa State University
The predaceous caterpillars of the butterfly Feniseca tarquinius feed on these aphids.
