Cheloninae
chelonine wasps
Cheloninae is a cosmopolitan subfamily of braconid parasitoid wasps, distinguished by a distinctive metasomal carapace formed from the fusion of the first three tergites. Members are solitary koinobiont endoparasitoids that primarily attack Lepidoptera, particularly Pyraloidea and Tortricoidea. They are egg-larval parasitoids, ovipositing into host eggs but completing development only after the caterpillar hatches and matures. Chelonines carry polydnaviruses that aid in suppressing host immune responses.
