Pterocheilus
Pterocheilus is a genus of fossorial mason wasps in the family Vespidae, subfamily Eumeninae. Unlike most potter wasps that nest in pre-existing cavities or construct free-standing mud nests, species in this genus excavate burrows in soil or sand. The genus exhibits its greatest diversity in southwestern North America, with approximately 40 species recognized in the region. Females possess specialized morphological adaptations for digging, including tarsal rakes on the forelegs and a psammophore—long setae on the labial palps used to transport excavated soil away from the nest entrance.

Pterocheilus denticulatus
Pterocheilus denticulatus is a solitary mason wasp in the subfamily Eumeninae, characterized by fossorial nesting behavior in sandy or soft soils. Females excavate burrows using specialized morphological adaptations including a tarsal rake on the front feet and a psammophore—a "beard" of long setae on the palps used to transport excavated soil away from the nest entrance. The species was described by de Saussure in 1855 and belongs to a genus of approximately 40 North American species, most diverse in the southwestern United States.

Pterocheilus diversicolor
Pterocheilus diversicolor is a species of solitary mason wasp in the subfamily Eumeninae, described by Rohwer in 1911. Like other members of the genus Pterocheilus, females are fossorial, excavating burrows in soil or sand using specialized tarsal spines and a psammophore (beard-like setae on the mouthparts) to carry excavated material away from the nest entrance. The species belongs to a genus of approximately 40 North American species with greatest diversity in the southwestern United States. Specific biological details for P. diversicolor remain poorly documented compared to better-studied congeners such as P. quinquefasciatus.

Pterocheilus hirsutipennis
A solitary mason wasp in the subfamily Eumeninae, Pterocheilus hirsutipennis is one of approximately 40 North American species in this genus. Like other Pterocheilus, females are fossorial, excavating subterranean burrows in sandy or soft soils rather than using pre-existing cavities or building mud nests. The species was described by Bohart in 1940 and is part of a genus whose members are most diverse in the southwestern United States. Most species biology remains poorly documented.

Pterocheilus mirandus
Pterocheilus mirandus is a solitary mason wasp in the family Vespidae, subfamily Eumeninae, described by Cresson in 1897. Like other members of the genus Pterocheilus, this species is fossorial, excavating burrows in soil rather than using pre-existing cavities or constructing mud nests. The genus is most diverse in the southwestern United States, with approximately forty North American species. Most Pterocheilus species are poorly known biologically due to their secretive nesting habits and effective concealment of burrow entrances.

Pterocheilus pedicellatus
Pterocheilus pedicellatus is a species of solitary mason wasp in the subfamily Eumeninae, described by Bohart in 1940. Like other members of the genus Pterocheilus, this species is fossorial, excavating burrows in soil rather than constructing above-ground mud nests or using pre-existing cavities. The genus is most diverse in the southwestern United States, with approximately forty North American species. Most Pterocheilus species are poorly known biologically, though related species provision their burrows with paralyzed caterpillars as food for their larvae.

Pterocheilus quinquefasciatus
Pterocheilus quinquefasciatus is a fossorial solitary mason wasp in the family Vespidae, subfamily Eumeninae. Females excavate burrows in sandy or soft soil rather than using pre-existing cavities or building mud nests. The species is relatively large for the genus, with females measuring 13–16 mm in body length. It has been documented using caterpillars of Heliothis phloxiphaga (Darker Spotted Straw Moth) as prey in Badlands National Park, South Dakota, with females paralyzing victims and carrying them in flight to the burrow.

Pterocheilus sinopis
Pterocheilus sinopis is a species of solitary mason wasp in the family Vespidae, subfamily Eumeninae. It is one of approximately 40 species in the genus Pterocheilus, a group characterized by fossorial (burrow-digging) nesting behavior. The species was described by Richard M. Bohart in 1999. Like other members of its genus, females are equipped with specialized anatomical adaptations for excavating soil burrows, including a psammophore (a "beard" of setae on the palps) for transporting soil away from nest sites.
