Specific parasitoid species usually attack specific insect species (specialist or monophagous) or a few closely related species (oligophagous).
Parasitoids are host stage specific - some parasitize eggs while others parasitize larvae/pupae.
Only the female parasitoid is involved in the act of parasitism. Many of them have a highly developed long ovipositor to lay eggs in their host body and in some cases they attack hosts that are inside plant tissue.
Only the larval stage of the parasitoid is parasitic; adults are free living and feed on nectar, honeydew or host insect body fluid.
Female parasitoids lay a single egg or several eggs in, on, or near the host body. Newly emerged parasitoid larvae feed inside the host body, and gradually destroy the host as it develops.
Pupation of parasitoids can take place either inside or outside the host body.
A parasitoid completes its development on one host individual.
