Xylotrupes socrates Nov 10, 2026 Natore, Bangladesh

Scientific Name: In the scientific world, this beetle is known as Xylotrupes socrates, and it is commonly called the Siamese rhinoceros beetle or fighting beetle. Family and Genus: According to the classification of the animal kingdom, it belongs to the subfamily Dynastinae of the family Scarabaeidae within the order Coleoptera. It is a recognized species under the genus Xylotrupes.

Origin and Habitat: They are widely distributed in Southeast Asian countries such as Bangladesh, Cambodia, China, India, Laos, Myanmar, Nepal, Thailand, and Vietnam. They are naturally found in forest areas and vegetation regions.

Food: Adult beetles typically feed on plant sap, tree bark, and sweet fruit juices, while their larvae feed on decaying wood and organic matter in the soil.

Benefits: They are famous for being used in traditional beetle fighting entertainment in northern Thailand, Myanmar, and Laos, which serves as a popular local pastime.

Harmful Aspects: They do not pose any major threat to humans, though large dynastid beetle larvae can occasionally feed on decaying plant roots or organic wood material in forest environments.

I learned about them from various sites including iNaturalist, Wikipedia and Google.
