Bolbocerosoma
earth-boring scarab beetles
Bolbocerosoma is a genus of earth-boring scarab beetles in the family Geotrupidae. The genus contains approximately 13 described species distributed across the Nearctic and Neotropical regions. These beetles are part of the subfamily Bolboceratinae, tribe Odonteini. The genus was established by Schaeffer in 1906 and has been subject to taxonomic revision by Howden (1955).
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 elongatum
Bolbocerosoma elongatum is an earth-boring scarab beetle in the family Geotrupidae, described by Howden in 1955. It is a member of the subfamily Bolboceratinae, a group characterized by fossorial (burrowing) habits. The species is known from North America, with records from Texas. Like other members of its genus, it exhibits the typical earth-boring beetle morphology adapted for digging in soil.
Bolbocerosoma tumefactum
Bolbocerosoma tumefactum is an earth-boring scarab beetle in the family Geotrupidae, native to eastern North America. The species is characterized by its distinctive tumescent (swollen) appearance, reflected in its specific epithet. Like other geotrupids, adults are typically associated with mammal dung and soil-burrowing activities. The species occurs across a broad range of eastern and mid-Atlantic states in the United States.
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.
