Darwin himself lends his name to this rare stag beetle, reflecting its significance to naturalists exploring South America. Found only in remote mountains of Argentina and Chile, this powerful insect wields impressive mandibles used in dramatic combat between males for breeding rights. These formidable 'antlers' make encounters between rivals intense battles, yet we know surprisingly little about this mysterious Andean icon hidden in mountain forests.
