Antlers are beetles in the order Coleoptera, also known as beetles. The upper jaw of male armor is highly developed and horn shaped, with a toothed protrusion on the inner edge that is very similar to deer antlers, hence it is called stag antler beetle. Antlers are distributed on all continents except Antarctica. Most people go out at night to search for food. In Taiwan, both adults and children are particularly fond of deer antler worms. But in recent years, some rare species have been on the brink of extinction due to excessive capture and sale, as well as deforestation in their habitats. Antlers are second-class protected animals in China, and buying and selling them is illegal.
