Chalcosoma caucasus (Fabricius, 1801)[1] Chalcosoma chiron (often called the Caucasus beetle) is a species of beetle in the family Scarabaeidae.

This species can be found from Malaysia south into Indonesia (Sumatra, Java, Malay Peninsula, Indochina) and Thailand in East region (Chanthaburi province, Sa Kaeo province).

[2] It was formerly known as Chalcosoma caucasus, a name which is a junior synonym and not valid.

The male has specialised enormous, curved horns on its head and thorax that it can use to fight with other males to gain mating rights with females.

The elytra of the females have a velvety texture, as they are covered by tiny hairs.
