Trachyderma hispida

These rugged darkling beetles navigate harsh arid terrains with a heavily textured, fused exoskeleton that traps a pocket of insulating air beneath the wing covers to prevent desiccation. Strictly flightless and primarily nocturnal, they forage slowly across sandy or stony ground at dusk, scavenging whatever organic debris winds or dunes deposit. When threatened, they often play dead or release faint defensive secretions from abdominal glands to deter desert predators.
