Atlas Beetle

Chalcosoma atlas, the Atlas beetle, is a large rhinoceros beetle found in the lowland tropical rainforests of Southeast Asia, including the Philippines and Indonesia. Males bear three horns—one cephalic and two thoracic—similar to the Caucasus beetle but with slightly more slender thoracic horns, reaching a total length of 50–120 mm. The species name references the Greek mythological titan Atlas. Body coloration is a glossy dark green to black. A medium to large enclosure with deep fermented substrate is appropriate. Females lay eggs directly in the substrate; the larval period lasts approximately 8–12 months. Adults are fed beetle jelly or banana. Its impressive three-horned form combined with manageable husbandry makes the Atlas beetle an excellent entry point into exotic beetle keeping. The difference from the Caucasus beetle is a common question—the Atlas has a slightly thinner, more upward-pointing thoracic horn and a somewhat smaller body, while the Caucasus has thicker, longer horns and is more aggressive. The Atlas is a bit easier to keep and is a popular entry species for first-time keepers of imported beetles. Prices run about 5,000-15,000 yen per pair.

The Atlas Beetle lives Adult 3-6 months, larva 8-12 months.

Adults live 3-6 months after emergence and the larval stage lasts 8-12 months, for a total lifespan of about a year from egg. That is typical for imported rhinoceros beetles, and the key to longevity is avoiding heat: above 28°C adults wear out and die sooner, so keeping them at a cool 22-26°C in summer extends their life.

The Atlas Beetle grows to Up to 100mm.

The ideal temperature for the Atlas Beetle is 22〜28℃.

Optimal captive temperature ranges from 22–28°C, and the species is considered one of the more accessible exotic rhinoceros beetles for beginners.
