Males have three prominent horns. The species is named for Atlas, the giant of Greek mythology who supported the skies. DescriptionChalcosoma atlas, like other beetles of the genus Chalcosoma, is remarkable for its size. As is common in the Scarabaeidae, males are larger than the females, reaching a length of about {{convert|60|-|130|mm}}; females are about {{convert|25|-|60|mm}}. Males have specialised horns on their 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) by the broader end of the cephalic (head) horn. LarvaeThe larva of the Atlas beetle is known for its fierce behavior, including biting if touched. Unverified reports exist of larvae that live together fighting to the death if they have insufficient space or food.{{Citation needed|date=November 2017}} DistributionC. atlas is found in Southeast Asia. ParasitoidsThe species is the host of a parasitoid, the giant scoliid wasp Megascolia procer, which has a paralysing venom.[1] Subspecies
