头部前方长着的巨大钳状大颚形似鹿角的甲虫。雄虫常用此颚与同类争斗或求偶，以树汁为食，力量强劲，能展开翅膀飞行。
This beetle has long, well-developed mandibles at the front of its head that resemble a deer's antlers. The large jaws are used by males to compete for strength or to attract mates. It feeds on sap from trees, is strong, and can spread its wings to fly.
