Fun facts
It hisses by pushing its wings down, which squeezes air out between its wings and back.
Each wing cover has four long white stripes and one short one. That makes ten lines in all.
The male uses his big fan-like feelers to smell the females. He folds them shut when he is scared.
Its grub can grow up to about 5 centimetres long and may stay a grub for as long as four years.
The grown-up beetles fly towards lights at night.
