Thus, aphids show very complex and rapidly changing within-year dynamics, with each clone going through several generations during the vegetative season and being made up of many individuals, which can be widely scattered in space. The survival of the eggs and/or overwintering aphids determines the numbers of aphids present the following spring ...

Aphidius wasps are endoparasitoids of aphids. The female wasp lays eggs in an aphid. When the eggs hatch, the wasp larvae feed on the inside of the aphid. As the larvae mature, the hosts die and become slightly enlarged or mummified, often becoming tan or yellow. Complete metamorphosis occurs within the host.
