Parasitic Wasp

Their larvae are either parasitic or predators. Most caterpillar are targeted host. Some species attacked other insects and spiders. The female wasp usually locates the food plants of the host then searches with her antennae for a suitable host. The female usually has the long ovipositor which is used to insert eggs into the host body. Some species lay eggs externally and attack the host from outside. The host will usually survive when the larvae is still living. Until the larvae fully grown, the larvae either pupates inside the dead host or form a cocoon outside.
