Macrohabitat: Lowlands, 30-300 meters altitude, in open thorn-tree areas among low, rolling hills. Microhabitat: Adults are ground-dwelling on well-drained caliche substrates, and in animal burrows. Dispersal abilities: Brachypterous, hence flightless thus vagility limited to walking or running; swift runners. Seasonal occurrence: Adults are active in April- May, and July- November. Behavior: Adults are nocturnal, taking cover during the day in mammal burrows, or under stones. Adults are predaceous on large insects and other terrestrial arthropods. Larvae are very large and form burrows in soft substrate on eroded hillsides, and near burrows of ground living mammals, such as badgers and armadillos.
