This is a huge source and loss of money to many people, especially in the Ryukyu Islands.
They will battle each other, trying to push each other off the log, the one to stay on the log is the winner. In the most popular game, two different male beetles are placed on a log. Japanese rhinoceros beetles are a very popular subject in gambling, like Siamese fighting fish and cricket fights. Japanese kabuto breeders are trying to find supplements to make the Japanese rhinoceros beetle mature faster and grow to a larger size. Male beetles normally die in the fall after mating many times, whereas female beetles normally die after laying eggs. Combat occurs between males competing for mates. But life as an adult is short in less than 4 months he must find and defend a territory and mate. The eggs are laid directly in the ground, then hatch into a wriggling larva, which usually mature in a year. They usually will die after mating and laying eggs. The earliest beetles will come out of the ground in late spring they will usually die around middle September to early October. The Japanese rhinoceros beetle will live most of its life underground, for it only lives about four months as an actual beetle. It can be found in broad-leaved forests in tropical and subtropical mountainous habitats. This species is present in Japan (Honshu, Kyūshū and other islands including Okinawa), Taiwan, Korean Peninsula and eastern China. The preferred foods are tree saps, fruits and anything sugary. Like all Dynastinae species, these beetles are strong flyers, although they never cover long distances during the flight. The body is dark brown, while the ventral part of the body is black, brilliant and the front legs are unusually long. Their eyes may be white or red and are adapted to low light levels, as this species is nocturnal. In addition to their impressive and ornate protuberance they also have a smaller thoracic horn, also forked. By means of their forked horn they lift other males off the ground and throw them into the air. The long cephalic horn of this species has a characteristic shape in the form of the letter Y and it is used by males during the mating period and to maintain territories. The males are much larger, reaching a length of 40–80 mm, while females can reach a length of about 40–60 mm. Mounted specimen Allomyrina dichotoma shows a striking sexual dimorphism.
