European Grain Weevil
A small, dark brown, flightless weevil that infests stored grain. It has been a pest since ancient civilizations first stored wheat.
Did You Know?
Specimens have been found in grain stores at ancient Egyptian archaeological sites thousands of years old.
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.
