Calosoma angulatum
angulate caterpillar hunter
Calosoma angulatum, commonly known as the angulate caterpillar hunter, is a large ground beetle in the family Carabidae. First described by Chevrolat in 1834, this species ranges from the southwestern United States through Central America into northern South America. It inhabits premontane moist forests and oak-savannah ecosystems. Adults are known to prey on Spodoptera frugiperda (fall armyworm), indicating a role as a predator of agricultural pest caterpillars.
Calosoma lepidum

Calosoma lepidum is a ground beetle in the subfamily Carabinae, described by John Lawrence LeConte in 1844. Adults are sub-brachypterous, indicating reduced flight capability. The species inhabits open prairie habitats with short grass in the northern Great Plains and adjacent montane regions.
Calosoma luxatum
dislocated beautiful black searcher
Calosoma luxatum, commonly known as the dislocated beautiful black searcher, is a large ground beetle in the family Carabidae. Adults are brachypterous, meaning they have reduced wings and are flightless. The species is distributed across western and central North America, from the Canadian prairies through the western United States. It inhabits open short grass prairies and dry forest clearings, where it hunts as an active predator.
Calosoma moniliatum
collared beautiful black searcher
Calosoma moniliatum, commonly known as the collared beautiful black searcher, is a large predatory ground beetle in the family Carabidae. Adults are brachypterous (short-winged and flightless). The species occurs in western North America, inhabiting short grass prairies and dry forests.
Calosoma simplex
simple beautiful black searcher
Calosoma simplex is a species of ground beetle in the subfamily Carabinae, described by John Lawrence LeConte in 1878. It belongs to the genus Calosoma, whose members are known for arboreal hunting behaviors and caterpillar predation. The species occurs in southwestern North America, including parts of the United States and Mexico. Like other Calosoma species, it likely functions as a predator of caterpillars and other soft-bodied insects.
