Bolbocerastes imperialis
Bolbocerastes imperialis is a species of earth-boring scarab beetle in the family Geotrupidae, first described by Cartwright in 1953. The species is native to North America and comprises two recognized subspecies: B. i. imperialis and B. i. kansanus. As a member of the Bolboceratinae subfamily, it exhibits the fossorial adaptations characteristic of earth-boring scarabs.
Bolbocerosoma hamatum
Bolbocerosoma hamatum is a species of earth-boring scarab beetle in the family Geotrupidae. The species was described by Brown in 1929 and is found in the southeastern United States. Like other members of its genus, it is associated with burrowing behavior in soil, though specific biological details remain poorly documented in the literature.
Bolbocerosoma ritcheri
Bolbocerosoma ritcheri is a species of earth-boring scarab beetle in the family Geotrupidae, first described by Howden in 1955. The species belongs to a genus characterized by their burrowing behavior and association with soil substrates. It occurs in parts of North America including Texas and northeastern Mexico.
Bradycinetulus
Bradycinetulus is a genus of earth-boring scarab beetles in the family Bolboceratidae, established by Cockerell in 1906. The genus contains at least three described species distributed in the Nearctic region. These beetles are robust, fossorial insects adapted for burrowing in soil. Field observations indicate adults are attracted to lights at night and have been collected from sand dune habitats and pack rat runs.
Ceratophyus
earth-boring scarab beetles
Ceratophyus is a genus of earth-boring scarab beetles comprising approximately 13 described species. These beetles are known for constructing underground brood chambers using dung, with documented cooperative nest-building behavior between males and females in at least one species. The genus occurs across the Palaearctic region, with species documented in Russia, China, and Mongolia. Some species possess horns used in intraspecific combat.
Eucanthus
earth-boring scarab beetles
Eucanthus is a genus of earth-boring scarab beetles comprising approximately eight described species. These beetles belong to the family Bolboceratidae (formerly placed in Geotrupidae), a group characterized by fossorial (burrowing) habits. The genus was taxonomically revised by Henry F. Howden in 1955 as part of a comprehensive treatment of North American Geotrupinae. Species are distributed across North America, with representatives occurring from the United States through Mexico and into South America.
Eucanthus impressus
Eucanthus impressus is a species of earth-boring scarab beetle in the family Geotrupidae, subfamily Bolboceratinae. It was described by Henry Howden in 1964 and is distributed across much of North America, with records from the United States and northern Mexico. The species belongs to a group of beetles commonly known as earth-boring scarabs due to their fossorial habits.
Eucanthus lazarus
Lazarus's Earth-boring Scarab Beetle
Eucanthus lazarus is a species of earth-boring scarab beetle in the family Bolboceratidae (sometimes historically placed in Geotrupidae). It occurs in North America, where it has been observed in association with animal dung. The species was originally described by Fabricius in 1775. A western subpopulation was once recognized as Eucanthus lazarus subtropicus, though this name is now generally treated as a synonym.
Eucanthus subtropicus
Eucanthus subtropicus is an earth-boring scarab beetle in the family Geotrupidae, described by Henry Howden in 1955. The species is found in southeastern North America, with records from Alabama through the Carolinas and Florida. Like other members of the genus, it excavates burrows in soil for larval development. Adults are attracted to light and have been collected in sand dune habitats.
Geotrupes balyi
Baly's earth-boring beetle
Geotrupes balyi is a species of earth-boring scarab beetle in the family Geotrupidae. It occurs in North America, with records from Canada and the eastern and central United States. As with other members of its genus, it is associated with mammal dung and forested habitats. The species was described by Jekel in 1865.
