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.
Glacial Stonefly
A small, slender stonefly found in the coldest alpine headwater streams. Its needle-like wings are rolled tightly around its body at rest.
Did You Know?
Its rolled-wing resting posture gives the family its common name of needle flies.
