The Metamorphosis of a Hercules beetle
The Japanese entomologist Hirofumi Kawano filmed the impressive metamorphosis of a Beetle Hercules, the longest rhinoceros beetle in the world. The wingspan, wings deployed, of this insect can reach 22 cm. The size of the male varies from 6 cm to 17.50 cm but rarely exceeds 15 cm. The male has two horns. One is the thoracic extension, the other, smaller and articulated, the cephalic prolongation, and this forms a "pinch". After the larval period of several years, the larva is transformed into a nymph from which an adult emerges.
