Life History. Where data are known, members of Geomyphilus are associated with rodent burrows, probably feeding on their dung. Known rodent hosts include pocket gophers and prairie dogs, but some data indicates rarer species may be with kangaroo rats, voles, or other rodents.
Larvae. Unknown.
Status of Classification. Gordon and Skelley (2007) recognize 3 species groups, which do not include the Mexican species placed here. These groups are based on external and genitalic characters, some of which appear variable or intermediate between groups.
