Bicyrtes
Bicyrtes is a genus of large, often brightly colored predatory sand wasps in the family Crabronidae. The genus name derives from the two noticeable projections arising from the rear of the mesosoma. Most species nest in sandy or coarse soils and provision their burrows with paralyzed true bugs, primarily Pentatomidae (stink bugs), though some species utilize Reduviidae (assassin bugs) and Coreidae (leaf-footed bugs) as prey. The genus contains approximately 11 described species distributed across North America, with some species extending into Central and South America and the Caribbean, including the Galápagos Islands.
