As the colonies grow, winged forms may be produced that seek out additional host plants. Some of these species may lay eggs, asexually, in the fall, which overwinter. The next group again lives on one plant or group of plants, but alternates from the spring asexual form of reproduction to a fall sexual cycle. Generally, these aphids overwinter in the egg stage. This female gives live birth to female aphids.
Asexual reproduction continues with wingless or winged forms being produced.
In late summer or fall, the asexual reproducing females produce sexuals, males and females. These sexual forms mate and lay eggs for overwintering. The most complicated aphid life cycles include not only alternation from asexual to sexual reproduction but also a switch of host plants. The spring and summer asexual forms live on one host but fly to an alternate plant for the production of the sexual forms. The sexual forms, after mating, return to the spring host plant to lay eggs.
