}} The Japanese rhinoceros beetle, Japanese horned beetle, or {{nihongo|kabutomushi|カブトムシ}}, Allomyrina dichotoma, is a species of rhinoceros beetle. EtymologyIn Japanese, rhinoceros beetles are called {{nihongo|kabutomushi|かぶとむし, also written 甲虫 or かぶと虫}}. Mushi is Japanese for insect, and kabuto is Japanese for helmet, literally referring to the samurai helmet.[2] The beetle's Korean name 'Jangsupungdeng-i(장수풍뎅이, "General beetle") is similar in nature. In Chinese the beetle is called '獨角仙' (which translates to 'single-horned immortal') or '雙叉犀金龜'. List of subspecies
DescriptionAllomyrina dichotoma shows a striking sexual dimorphism. The males are much larger, reaching a length of 40–80 mm, while females can reach a length of about 40–60 mm. 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.[2] By means of their forked horn they lift other males off the ground and throw them into the air.[2] In addition to their impressive and ornate protuberance they also have a smaller thoracic horn, also forked. Their eyes may be white or red and are adapted to low light levels, as this species is nocturnal.[2] The body is dark brown, while the ventral part of the body is black, brilliant and the front legs are unusually long. Like all Dynastinae species, these beetles are strong flyers,[2] although they never cover long distances during the flight. The preferred foods are tree saps, fruits and anything sugary.[4]Distribution and habitatThis species is present in Japan (Honshu, Kyūshū and other islands including Okinawa), Taiwan, Korean Peninsula and eastern China.[5] It can be found in broad-leaved forests in tropical and subtropical mountainous habitats. LifespanThe eggs are laid directly in the ground, then hatch into a wriggling larva, which usually mature in a year.[4] But life as an adult is short; in less than 4 months he must find and defend a territory and mate. Combat occurs between males competing for mates. Male beetles normally die in the fall after mating many times, whereas female beetles normally die after laying eggs. Japanese kabuto breeders are trying to find supplements to make the Japanese rhinoceros beetle mature faster and grow to a larger size. In Japanese cultureJapanese rhinoceros beetles are very popular in anime, tokusatsu, advertisements, televisions, and films in Japan. Many children in Japan buy or catch these beetles and breed them. Male and female insects will cost about 500 to 1000 yen (approximately five to ten US dollars). This beetle is sold as a pet in department stores[4] in many countries of Asia where it is also frequently depicted in popular media as a common cartoon character for various uses, for example much as gorillas, lions, or T. rex are seen in advertisements and product labels in the United States.{{cn|date=March 2018}} {{main|Insect fighting}}Japanese rhinoceros beetles are a very popular subject in gambling, like Siamese fighting fish and cricket fights. In the most popular game, two different male beetles are placed on a log.[4] They will battle each other, trying to push each other off the log, the one to stay on the log is the winner. This is a huge source and loss of money to many people, especially in the Ryukyu Islands. Bibliography
