biology
Macrohabitat: Lowlands, sea level – 343 meters altitude, in open forests (e.g.
Pinus), pastures, on dunes and beaches. Microhabitat: Adults are ground-dwelling on exposed
or slightly shaded dry, sandy substrate. Dispersal abilities: Brachypterous, hence
flightless therefore vagility limited to walking or running; moderate runners, strong burrowers.
Seasonal occurrence: Adults have been found in January – December. Behavior: Adults
are diurnal and nocturnal, predaceous xerophiles, and are often active in the sunshine; they
take cover in burrows they dig in the substrate under logs, stones, boards, and dry cow and
horse dung. They are solitary. Adults feed on lepidopterous caterpillars and other insect larvae.
Adults overwinter in burrows they dig in the substrate down to 15 cm, as well as under logs.
They are attracted to lights, arriving by walking.
