Onthophagus cavernicollis
Cave-dwelling Dung Beetle
Onthophagus cavernicollis is a dung beetle species in the family Scarabaeidae, first described by Howden and Cartwright in 1963. The species epithet "cavernicollis" suggests a possible association with cave or subterranean habitats, though specific ecological details remain limited. Like other members of the genus Onthophagus, it is presumed to be a dung-feeding beetle involved in nutrient recycling. The species has been documented in the south-central United States.
Onthophagus mextexus
Onthophagus mextexus is a dung beetle species in the family Scarabaeidae, described by Howden and Cartwright in 1970. The species occurs in montane regions of northeastern Mexico and southern Texas, USA. As a member of the genus Onthophagus, it is presumed to be a tunneler dung beetle that buries dung for larval development, though specific natural history details remain undocumented. The species was described from specimens collected in the Mexican states of Guanajuato, Hidalgo, Nuevo León, Puebla, San Luis Potosí, and Veracruz.
