Like most dynastid beetles, the adult male of X. socrates possesses two horns: one on the head and another on the pronotum, both bifurcate and curling inward. Adult females lack these horns. Both sexes have dark chestnut-brown (in younger beetles) or black (in older beetles) exoskeletons and elytra.[1]
These beetles are used for staging beetle fights, a traditional form of entertainment popular in the northern region of Thailand.[failed verification] They are captured and trained to become stronger and more aggressive.[3] In the fight the beetle that lifts its opponent up by its horns wins. A beetle may also win if his opponent crawls away, falls, or is overturned.[4] Insect fighting is mostly practiced in the Chiang Mai and Nan provinces of Thailand. It is also popular in Myanmar and Northern Laos. Spectators typically place bets on the fights.[5] Insect fighting coaches claim their activity provides a free pastime while drawing attention to insects that would otherwise have been ignored or simply killed as pests.[6]
