Chalcosoma caucasus

The Atlas beetle (Chalcosoma atlas or Chalcosoma Caucasus)is a very large species of beetle in the family Scarabaeidae, found in Southeast Asia. Males have three prominent horns. The species is named for Atlas, the giant of Greek mythology who supported the skies. Chalcosoma atlas is found in Southeast Asia.


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.


Atlas beetles have always been an interesting species to human beings. Their scientific name is Atlas beetle Chalcosoma atlas which signifies that they belong to the Chalcosoma species. Collecting them is a hobby that most people enjoy. Their attractive and strong body makes them very popular amongst humans. Their exoskeleton comes in different colors which is also interesting to the collectors. Atlas beetles are mostly found in Southeast Asia, primarily in Malaysia. They look absolutely spectacular and are extremely strong creatures. Atlas beetle larvae are known to be very aggressive and will bite anyone trying to touch them. The male Atlas beetles are almost twice the size of a female beetle. Atlas beetles use their horns and strength to dig deep into the leaf litter to avoid predators.


The beetles start their life as larvae about the size of a human thumb living in the trunks of fallen trees and eating the rotting wood. After two years they become pupae and eventually hatch into beetles when they feed on plant nectar and fruit. Although they can fly, atlas beetles are so heavy that they have trouble getting into the air from the ground, so to become airborne they usually launch themselves off trees. They are found mainly in Malaysia. Atlas beetle lifespan is around 12 months when kept in hospitable conditions. Atlas beetle lives longer in captivity as they are not prone to any external threat. Also, the Atlas beetle horns in males help them to live for a longer duration as compared to females, who die soon after laying eggs.
