甲蟲頭部前方有如鹿角般長長突出的大顎。雄蟲用此大顎較力或吸引雌蟲。以樹液為食，力氣強勁並能展翅飛翔。
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.
