Boreocanthon melanus

Boreocanthon species are small dung beetles that can be distinguished from the similar genus Canthon by subtle morphological features; B. melanus specifically would require examination of elytral coloration and genitalic structures for definitive identification from congeners. The species appears dark in coloration based on the specific epithet "melanus" (meaning black).

Sand dune habitats and associated mesquite/oak chaparral in arid regions. Observed in vegetated sand dunes with scattered Quercus havardii (shinnery oak) and surrounding grassland areas.

Known from eastern New Mexico, specifically Chaves County. The broader distribution likely extends through the southwestern United States given the genus range, but specific records are sparse.

Adults have been observed active in mid-May in New Mexico.

Dung; specifically observed rolling small rodent scats.

Rolling behavior observed: individuals were seen rolling small rodent scats across sandy substrate, similar to other Canthonini dung beetles. This telecoprid (rolling) behavior involves forming dung into balls and transporting them for burial and consumption.

As a dung beetle, contributes to nutrient cycling and soil aeration through burial of small mammal dung. This ecological function is particularly important in arid sand dune ecosystems where decomposition rates are slow.

• Canthon spp.Similar small size and dung-rolling behavior; Boreocanthon is distinguished by subtle morphological features including elytral structure and male genitalia.
• Boreocanthon conformisCongeneric species with potentially overlapping distribution; would require detailed examination to distinguish.
