    Chalcosoma Caucasus macro shots
Chalcosoma Caucasus
Chalcosoma Caucasus, like other beetles of the genus Chalcosoma, is remarkable for its size, that can reach a length of about 25–60 millimetres (0.98–2.4 in) in the females. As common in some Scarabaeidae, the males are larger than the females, reaching a length of about 60–130 millimetres (2.4–5.1 in). The males have specialised horns on the head and thorax that they use to fight with each other to gain mating rights with females. The Atlas beetle differs from other Chalcosoma species (such as C. caucasus) in the end of the cephalic horn of the Atlas, which is broadened.
