Braconid wasps are parasitic on some caterpillars, boreres, weevils and beetles, making them a beneficial garden visitor. Life Cycle . The viruses exhibit a complex and initmate genetic relationship with the wasp, since viral sequences are integrated within the wasp's chromosomal DNA. Until these parasites become adults, braconids are either ectoparasitic insects or endoparasites, meaning these pests consume other insects as a form of nutrition. These moths overwinter in the soil as dark brown pupae, then emerge . When ready to pupate, the larvae chew their way out of the host pest and make tiny silk cocoons on its exoskeleton.
