Sphex tepanecus
Sphex tepanecus is a species of thread-waisted digger wasp in the family Sphecidae. It is a large solitary wasp known from the western United States, with records from Arizona, Colorado, and potentially Idaho. Like other members of the genus Sphex, it constructs subterranean nests and provisions them with paralyzed prey for its larvae. The species was first described by de Saussure in 1867.
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.
