Pachysomoides
Pachysomoides is a genus of ichneumon wasps in the family Ichneumonidae. These small parasitoid wasps specialize in attacking paper wasps (Polistes spp.) and related social wasps. Two species are documented in North America: P. fulvus, which ranges broadly across the continent, and P. stupidus, found in the southeastern United States. The genus exhibits gregarious parasitoid behavior, with multiple larvae sometimes developing on a single host.
