Bolbocerosoma biplagiatum
Bolbocerosoma biplagiatum is a species of earth-boring scarab beetle in the family Geotrupidae, described by Dawson & McColloch in 1924. It belongs to the subfamily Bolboceratinae, a group characterized by their burrowing behavior and association with soil and organic matter. The species is known from the central United States, with records spanning from Colorado to Wisconsin and southward to Texas and Oklahoma.
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 rex
earth-boring scarab beetle
Bradycinetulus rex is an earth-boring scarab beetle described by Cartwright in 1953. It belongs to the family Geotrupidae, a group commonly known as earth-boring dung beetles for their habit of digging burrows in soil. The species is known from the Nearctic region, with records from Texas. Like other members of its genus, it likely exhibits the fossorial (burrowing) habits characteristic of the family.
Eucanthus greeni
Green's Earth-boring Scarab Beetle
Eucanthus greeni is a species of earth-boring scarab beetle in the family Geotrupidae. It is found in North America, with recorded occurrences in the western United States, central Canada, and northern Mexico. The species belongs to a genus of beetles known for burrowing behavior in soil. As with other members of Geotrupidae, it likely participates in soil ecosystem processes, though specific ecological details remain limited in available literature.
Geotrupes blackburnii blackburnii
Blackburn's earth-boring beetle
Geotrupes blackburnii blackburnii is a subspecies of earth-boring scarab beetle in the family Geotrupidae. It is a medium-sized beetle with entirely black coloration and a nearly impunctate pronotum, distinguishing it from the closely related G. splendidus. Adults are most commonly encountered in fall, particularly on mild days, and are frequently found on or near animal dung in high-quality woodland habitats. The species has a broad distribution across eastern North America.
Geotrupes hornii
Horn's earth-boring beetle
Geotrupes hornii is a species of earth-boring scarab beetle in the family Geotrupidae. It is found in the northeastern United States and southeastern Canada. Adults are most commonly observed between June and September, with peak activity in August. The species belongs to a group of beetles known for burrowing behavior and association with soil and organic matter.
Geotrupes splendidus
Splendid Earth-boring Beetle
A large, metallic earth-boring beetle in the family Geotrupidae, native to eastern North America. Adults are most commonly encountered in late fall and early winter, walking clumsily on trails through high-quality woodlands in search of mammal dung for feeding and oviposition. The species exhibits notable color polymorphism, with eastern populations typically bright green and western populations (including Missouri) ranging from yellow-green with golden or reddish hints to dark purple. Unlike true dung beetles, adults frequently feed on fungus and leaf litter, though dung remains important for larval development.
Geotrupes ulkei
Ulke's earth boring beetle, Ulke's Earth-boring Scarab
Geotrupes ulkei is a species of earth-boring scarab beetle in the family Geotrupidae. The species is currently classified under the genus Geotrupes, though some taxonomic sources list it as a synonym of Cnemotrupes ulkei. It is one of several North American species in this genus of burrowing beetles that utilize mammal dung and other organic materials for larval development.
Odonteus floridensis
Odonteus floridensis is a species of earth-boring scarab beetle in the family Geotrupidae, described by Wallis in 1928. It is endemic to Florida, where it inhabits sandy scrub habitats. As a member of the Bolboceratinae, it is adapted for burrowing in soil.
