Xylotrupes socrates, the Siamese rhinoceros beetle or fighting beetle, is a species of large scarab beetle belonging to the subfamily Dynastinae. It is particularly known for its role in insect fighting in Thailand, where they are captured and trained by their owners to become stronger and more aggressive, with the beetle that lifts its opponent up by its horns winning. An insect may also win if its opponent crawls away, falls or is overturned.
