Stizoides renicinctus
Stizoides renicinctus is a kleptoparasitic sand wasp in the family Crabronidae, one of only two species in its genus occurring in North America. The species has no common English name. It is known for its distinctive black body with a red or orange band on the second abdominal tergite, dark wings with translucent tips, and elongate build. Males are frequently observed visiting flowers for nectar, while females actively seek out the burrows of host wasps to exploit their food stores. The species exhibits unusual social behaviors including nighttime sleeping clusters and weather-related aggregations.

The species is distributed in North America and Middle America, with museum holdings documented from the UCR Entomology Research Museum. As a member of the Crabronidae, it is likely a predatory wasp, though specific biological details for this species remain poorly documented in available sources.
