This sport is common throughout several east and southeast Asian cultures, usually involving the large horned beetles of the Rhinoceros beetle subfamily (Dynastinae), whose members include the awesome Hercules beetle (Dynastes hercules) and the Atlas beetle (Chalcosoma atlas). The large “horns” of the males are used for territorial fighting, where they will wrestle in an attempt to topple one another, until one submits, retreats, or is knocked-off a perch. Fighting these beetles is a popular gambling sport throughout Asia, from Thailand to Hong Kong (another link).
In Japan, collecting and fighting these beetles is common among boys – Rhinoceros beetles are easy pets to care for. These fighting pets are common enough in Japan that one can even buy Rhinoceros beetles from streetside vending machines (photo from the Photomann gallery of Japanese vending machines), and there are many Japanese toys and models that relate to Rhinoceros beetle collecting. Also, this practice is the likely origin of the Japanese game Pokémon, which gained world popularity in the late 1990’s, and which focuses on the collecting, husbandry, and fighting of supernatural creatures.
There are also dire “blood sport” forms of bug fighting, involving more dangerous insects, arachnids, and crustaceans – as seen on the website Japanese Bug Fights! (sadly, sometimes the matches end in fatalities).
