The elephant beetle (Megasoma elephas) is a member of the family Scarabaeidae and the subfamily Dynastinae.

Horns as Weapons
Horns don’t just give the beetles a distinctive appearance: they have a practical purpose that helps the beetle survive. Competition for female beetles can be very intense during mating season. When two male elephant beetles both want the same female, they settle the matter by using their horns to fight. Horns are also useful as tools. The beetles use them to dig into sandy soil to create holes for hiding and to lift up bark to get to the tasty sap underneath.
