Giant Bark Aphid
The largest aphid in North America, with a body up to 6 mm long. It is grayish-brown with dark wing markings and feeds in conspicuous colonies on the bark of hardwood trees.
Did You Know?
Colonies on tree bark produce so much honeydew that it rains down onto cars, sidewalks, and outdoor furniture, creating a sticky nuisance in urban areas.
Cabbage Whitefly
A small white-winged insect that infests brassica crops, weakening plants with sap feeding and honeydew production. Populations have increased dramatically in European cabbage and kale crops.
Did You Know?
Unlike most whiteflies, it thrives outdoors in cool temperate climates rather than in tropical greenhouses.
