Eupatorus gracilicornis The five-horned rhinoceros beetle has been found in China, India, Myanmar, Thailand, Laos and Vietnam.[1] Its coloring is shiny jet-black, while the elytra or fore wings are colored yellow or gold. The body is covered by a thick exoskeleton and a pair of thick wings lay atop another set of membranous wings underneath, allowing the beetle to fly, although not very efficiently, owing to its large size.

The flying season is usually in September, when most of the males usually appear to wait for copulation. Its length is 50–95 mm. As a larva, its diet is rotten wood. Its adult diet consists of nectar, plant sap and fruit. It was first described by the British entomologist Gilbert John Arrow in 1908.

Eupatorus is a genus of rhinoceros beetles. The genus contains the following species:[2]
