Guides
Bolbocerosoma pusillum
Bolbocerosoma pusillum is a species of earth-boring scarab beetle in the family Bolboceratidae, described by Dawson and McColloch in 1924. The species is distributed across North America and comprises two recognized subspecies: the nominate form B. p. pusillum and B. p. townesi described by Howden in 1955. Like other members of the genus, this species is associated with burrowing behavior in soil and is attracted to light sources at night.
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.
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 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.
Odonteus filicornis
earth-boring scarab beetle
Odonteus filicornis is an earth-boring scarab beetle in the family Geotrupidae. The species was described by Thomas Say in 1823. It is native to North America and has been documented across the central United States and southern Canada.
