Meteorus rubens
Meteorus rubens is a gregarious larval parasitoid wasp in the family Braconidae that attacks significant agricultural pests, particularly the black cutworm (Agrotis ipsilon). Female wasps demonstrate strong attraction to host kairomones, with 94.3% responding to hexane extracts of their host compared to only 22.3% of males. The species has been shown to carry Rioviridae RNA viruses, a rare trait among parasitoids. It naturally coexists with other parasitoids such as Apanteles ruficrus, with which it exhibits niche partitioning based on host instar preference.
