Three-horned rhinoceros beetle

Three-horned rhinoceros beetle

Chalcosoma moellenkampi

A species of Giant asian rhinoceros beetle, Also known as Bornean three-horned beetle

The three-horned rhinoceros beetle is very recognizable due to the three prominent horns on its body. It actually has a very small geographic distribution, only being found on the island of Borneo. There, they live in rainforests and feed on the sap of trees, where males and females often meet. Males are very aggressive towards each other and use their horns to assert dominance.

Habitat Preferences of Three-horned rhinoceros beetle Through Different Life Stages
Eggs of three-horned rhinoceros beetle are typically deposited in decaying wood or compost where they can remain hidden and moist. Larvae usually inhabit nutrient-rich, rotten wood or compost heaps, where they feed and develop. The search for larvae would involve sifting through decomposing organic matter in forested areas. Pupation occurs within a cocoon made from surrounding material; thus, one might search in similar environments as for larvae but look for small, rounded structures. Adults are often found near food sources like sap flows on trees, ripe fruits, or in areas with abundant flowers, where they feed on the nutrients these sources provide. To observe adults, night-time searches near light sources can also be fruitful as they are attracted to light.

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 60–130 millimetres (2.4–5.1 in); females are about 25–60 millimetres (0.98–2.36 in).
