Parasitoids live and develop either within their host (endoparasitic) or outside of it (ectoparasitic). In most endoparasitic species, adult parasitoids oviposit (lay or insert) an egg into the body of the host, where it grows while gaining nourishment from within the host’s body. The host dies after the parasitoid emerges to pupate. In ectoparasitic species, adult parasitoids paralyze the host and oviposit an egg on the outside of the host’s body. The host is then taken back to a nest where the larvae can develop outside of the host’s body without being disturbed.
