Thyreodon atricolor
Thyreodon atricolor is a large ichneumonid wasp in the subfamily Ophioninae, described by Olivier in 1811. Members of this genus are among the largest Ophioninae in North America. The species is known from the southwestern United States and has been subject to taxonomic confusion with related species. Like other Ophioninae, it possesses a short, sharp ovipositor capable of delivering a sting, distinguishing it from many other ichneumonid subfamilies.
