Rhinoceros beetle

I saw this remarkable-looking beetle just before I went on holiday: it’s a Japanese rhinoceros beetle, about 5 cm long. Wikipedia tells me that they’re sold as pets in Asia (I remember seeing the film ‘Beetle Queen Conquers Tokyo’ at Bristol’s Watershed a couple of years ago, which gives an insight into the Japanese interest in insects as pets), and that gambling on fighting rhinoceros beetles is popular. I prefer to see them in the wild.
