Biology

Macrohabitat: Midlands, 540-1460 meters altitude; in grasslands, hilly prairies, pastures, and on well-drained bare, or sparsely vegetated areas. Microhabitat: Adults are ground-dwelling on open dry clay and sandy substrate, often on banks near creeks, rivers, ravines, and bluff tops. Dispersal abilities: Brachypterous, hence flightless thus vagility limited to walking or running; slow runners. Seasonal occurrence: Adults are active in April-September in the southern part of its range, and June- August in the northern part. Behavior: Adults are nocturnal, taking cover during the day in mammal burrows, or under stones. Adults are predaceous on large insects and other arthropods. Larvae are mainly active at night and on cloudy days; they are very large and form clusters of burrows in soft substrate near burrows of ground living mammals, such as badgers and gophers, and also in substrate of near-vertical dry clay banks and cliffs. Larvae do not have physiological adaptations to survive large term flooding.
