Chiron Beetle
Chalcosoma chironAlso known as Caucasus Beetle, Giant Rhinoceros Beetle
Chiron beetles rank among the heaviest and most formidable insects on Earth, distinguished by the male's lustrous metallic sheen and trio of enormous, forward-curving horns. Males gather along canopy wounds to drink weeping tree sap, using their horns as levering pincers to violently dislodge rival suitors from tree trunks. After mating, females burrow into decaying fallen logs where their massive grubs spend up to two years feeding on rotting wood and cycling forest nutrients.
