Bolbocerosoma biplagiatum
Dawson & McColloch, 1924
Bolbocerosoma biplagiatum is a of earth-boring scarab beetle in the Geotrupidae, described by Dawson & McColloch in 1924. It belongs to the Bolboceratinae, a group characterized by their burrowing 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.

Identification
Members of the Bolbocerosoma can be distinguished from other Geotrupidae by their compact, convex body form and the structure of their and adapted for digging. The specific epithet 'biplagiatum' suggests the presence of two spots or markings on the , though detailed diagnostic features for this are not well documented in available sources.
Habitat
Based on the distribution records and the of related Bolboceratinae, this likely inhabits open grassland and prairie with well-drained soils suitable for burrowing. The Bolbocerosoma is associated with sandy or loamy soils where construct burrows.
Distribution
Nearctic region: United States (Colorado, Iowa, Kansas, Nebraska, Oklahoma, Texas, Wisconsin). The appears to be centered in the Great Plains and adjacent regions.
Behavior
Like other bolboceratine geotrupids, are likely burrowers. The is known for constructing burrows in soil, though specific behavioral details for B. biplagiatum are not documented.
Ecological Role
As a member of the Geotrupidae, this likely contributes to soil aeration and nutrient cycling through its burrowing activities. The is generally associated with decomposition processes, though bolboceratines are less directly tied to than some other geotrupid .

Taxonomic note
The classification of Bolboceratinae has been subject to revision. Some authorities have treated Bolboceratidae as a separate , but current treatments (including Catalogue of Life) place it as a within Geotrupidae.
Data gaps
Despite being described a century ago, this remains poorly known biologically. No detailed studies of its , larval development, or specific requirements have been published.
