entomophagous parasite
Entomophagous parasites (coined from Greek entomon "insect" and Gk. -phagos "eater of") are insects that are parasitic on other insects. Nearly all insects are attacked by one or more insect parasites. This parasitic mode of life is most often confined to the larvae with the adults usually leading free lives. The vast majority of Hymenopterous insect parasites are usually restricted to specific hosts, such as Embidobia (parasitic on Embioptera), Platygaster and Polygnotus (on Cecidomyiidae), Scelio (on locust eggs) and Aphidius (on Aphids). Often, species that are hyperparasites are less host-specific.
== Parasitoids ==
Species whose feeding on the host leads to the certain death of the host, typically before the host reached reproduction, are termed parasitoids. In some cases, the larvae feed externally on paralyzed hosts, typically provided by the parent in special brood chambers; this life history is common among Scoliidae, Thynnidae, Mutillidae, and other predatory wasps. Others seek the eggs, larvae or pupae of various insects and deposit their eggs within them. The larvae develop on these stages of the host, killing it in the end. The parasitoid mode of life is common in Hymenoptera, especially within the Ichneumonoidea, Chalcidoidea and Proctotrupoidea and in Diptera (Tachinidae).
Strepsiptera differ in that the adult males live free lives with the females remaining as endoparasites, in a larval like state, feeding on the host in many Neuroptera and in the Epipyropidae among Lepidoptera.
