Life Cycle
Koinobiont endoparasitoids on Lepidoptera. Females lay egg(s) inside host caterpillars (thus endoparasitoids). Some species are gregarious (more than one egg is laid in a host by a female), or solitary (only one egg per host laid by a female). Eggs or first stage parasitoid larvae remain quiescent (koino = 'hidden' (Greek)) in the host until a certain host larval growth stage is reached, at which time the parasitoid larva begins eating and growing very quickly. The parasite always kills the host, thus the term "parasitoid."
