Macrohabitat: Lowands to uplands, 124 – 1890 meters altitude, in grasslands.
Microhabitat: Adults are ground-dwelling on exposed dry or muddy substrate with sparse
vegetation (e.g., patches of grass, yuccas, etc.). Dispersal abilities: Brachypterous, hence
flightless therefore vagility limited to walking or running; moderate runners, strong burrowers.
Seasonal occurrence: Adults have been found in April – November. Behavior: Adults are
nocturnal, predaceous, and take cover during the day in burrows they dig in the substrate. In
the northern part of their range, adults overwinter in the substrate; in the southern part, they
likely aestivate during the dry season in the substrate.
