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.
White Miller Caddisfly
A small white caddisfly commonly found near lights along eastern North American waterways. Its delicate white wings make it easily recognizable.
Did You Know?
White millers swarm around riverside lights in such numbers that they can create slippery hazards on bridges and roadways.
