Patagonian Darkling Beetle
A flightless darkling beetle endemic to Patagonian steppe habitats, with a rounded, heavily ridged black exoskeleton. It is adapted to the harsh, windy conditions of southern Argentina, sheltering under stones and shrubs during the day. It is an important detritivore in this arid ecosystem.
Did You Know?
Its heavily ridged elytra are fused shut, making it flightless but providing excellent protection against desiccation in Patagonia's dry winds.
Passalid Beetle
A large, glossy black beetle that lives in family groups inside rotting logs. Adults and larvae communicate using squeaking sounds produced by rubbing body parts together.
Did You Know?
Parents chew wood into pulp to feed their young, making them one of few beetles with true parental care.
