Chalcosoma atlas | |
Chalcosoma 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 60–120 millimetres (2.4–4.7 in); females are about 25–60 millimetres (0.98–2.36 in). 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.
The 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]
Chalcosoma atlas is found in Southeast Asia.
The species is the host of a parasitoid, the giant scoliid wasp Megascolia procer, which has a paralysing venom.[1]
