(Oryctes nasicornis), an insect of the family Scarabaeidae. The body is massive (length, up to 4 cm) and chestnut brown. The legs are thick and strong: the anterior ones are fossorial, the posterior ones have supporting denticles and spines. The male has a curved horn on his head.
The rhinoceros beetle is distributed in Europe from mixed forests to the steppes. It flies at the onset of darkness. The larvae are thick, yellow-white, C-shaped grubs (length, up to 10 cm) which feed on decomposing vegetable matter (decaying wood, dung, and so on). The beetle sometimes damages the roots of hothouse plants.
