The Megasoma or Elephant Beetle are black in color and covered with a coat of fine microscopic hairs. The hairs grow particularly thick on the beetle’s elytra. These hairs give the beetle’s body a yellowish color. Males have two horns protruding from the head and another from the prothorax. The horns are used for defense, and in competition among males for food and mates. Females have no horns. They live in rainforests and are mainly active during the night. Elephant beetle populations have been depleted by the destruction of the rain-forests, which has reduced their grounds for mating. In some countries such as Costa Rica, Nicaragua and others the male’s head is used as a charm necklace, decorated with gold, a practice that has affected the population severely.
