Crabronini
Guides
Anacrabro
Anacrabro is a genus of square-headed wasps in the family Crabronidae containing approximately 15 described species. Two species occur in North America north of Mexico: A. ocellatus, widespread east of the Rocky Mountains, and A. boerhaviae in the extreme southwestern U.S. and Mexico. The genus is distinguished from related crabronine wasps by its concave abdominal underside and, in A. ocellatus, by its specialized predation on plant bugs (Miridae) rather than flies.
Ectemnius dilectus
Ectemnius dilectus is a solitary wasp in the family Crabronidae, tribe Crabronini. It belongs to a genus of digger wasps that primarily prey on flies (Diptera), distinguishing them from related genera such as Anacrabro that hunt plant bugs. The species is recorded in North America, with distribution records from Canada including Alberta. As a member of Crabronini, it is fossorial, constructing underground nests for rearing offspring.
Ectemnius ruficornis
square-headed wasp
Ectemnius ruficornis is a species of square-headed wasp in the family Crabronidae. It is a solitary, fossorial wasp that constructs underground nests. The species has two recognized subspecies: E. r. ruficornis (Zetterstedt, 1838) and E. r. taiwanus Tsuneki, 1968. It has been recorded across Europe, Northern Asia, North America, and Southern Asia.
Ectemnius scaber
Ectemnius scaber is a species of square-headed wasp in the family Crabronidae. It is found in North America. The species has two recognized subspecies: Ectemnius scaber rufescens and the nominate Ectemnius scaber scaber.
Lestica
Lestica is a genus of square-headed wasps in the family Crabronidae, containing at least 40 described species. The genus belongs to the tribe Crabronini, which includes primarily predatory wasps that provision nests with prey for their larvae. Species of Lestica are distributed across multiple continents, with records from Europe, North America, and tropical Africa. The genus can be distinguished from similar crabronine genera by morphological features of the abdomen.
Rhopalum atlanticum
Rhopalum atlanticum is a species of solitary wasp in the family Crabronidae, described by R. Bohart in 1974. The genus Rhopalum comprises small, predatory wasps known as sand wasps that provision nests with paralyzed prey. This species occurs in North America and Middle America. Like other members of its genus, it likely excavates burrows in sandy soils and hunts small insects to provision larval cells.
