Aphid Sex!!!

Aphid Sex!!! For most of the year aphids reproduce asexually, cloning themselves over and over again, occasionally producing winged forms that fly off to new host trees and start new clonal colonies. Well before winter sets in they change strategies and start producing sexual reproductive females and males. The males mate with these new females and instead of cloning themselves the females lay eggs which survive the winter and the cycle starts all over again next year.
