Winged aphid (plant louse)

Usually found on plant stems, leaves, and new growth; winged individuals disperse through gardens, fields, and homes near infested plants.

Pierces plants and sucks phloem sap. It may excrete sticky honeydew, which can support sooty mold and attract ants.

Rapidly reproduces, often clonally, producing winged forms when plants are crowded or conditions deteriorate. Winged adults disperse to establish new colonies.

Generally harmless to people, but heavy infestations weaken plants and may transmit plant viruses. Aphids are important prey for lady beetles, lacewings, hoverfly larvae, and parasitoid wasps.
