Aphid

Tiny sap-sucking insects with extraordinary reproduction. Can reproduce without mating (parthenogenesis) and give birth to live young that are already pregnant, telescoping generations.

💡

Did You Know?

Aphids can telescope generations — a female can contain a developing daughter, who already has a developing granddaughter inside her, all without mating.

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.
