The aphids overwinter in the egg stage near the base of flower buds. They hatch when the buds bloom. The adults will remain wingless for 3-13 generations before winged adults appear during warmer weather in June/July. The winged adults will move to reed grasses or cattails, while the wingless adults will remain on the fruit tree. The winged adults return to the fruit trees in the fall to lay eggs which will overwinter. (2)
