Larvae of ectoparasitic wasps on caterpillar

Gregarious, ectoparasitic larvae on a caterpillar. I think they are wasps in genus Euplectrus. Females apparently inject hosts with a venom that prevents the caterpillar from molting, thus preventing the caterpillar from shedding the larvae along with the discarded skin. Caterpillar was approximately 12mm long, and very, very active. Media, PA.
