Hexarthrius mandibularis sumatranus

Hexarthrius mandibularis sumatranus, commonly known as the Sumatran giant stag beetle, is one of the largest and most impressive stag beetle species. Native to the rainforests of Sumatra, these beetles are prized by collectors for their massive mandibles and striking dark coloration. Males can reach lengths of 80–100mm, with dramatically enlarged jaws that make them formidable and visually stunning. Females are smaller and lack the pronounced mandibles. These beetles are nocturnal and feed on tree sap and decaying wood in their natural habitat. Perfect for serious insect enthusiasts and collectors seeking a remarkable specimen that showcases the incredible diversity of Indonesian fauna.
