The Dung Beetle (qiāng láng, English Dung Beetle), commonly known as dung beetles, belongs to Coleoptera Scarabaeidae. Black or dark brown body, large and medium-sized insects. Dung beetles can locate themselves by moonlight polarization to help them feed. It has certain phototaxis. There are more than 2, species of dung beetles in the world, which are distributed in any continent except Antarctica. The most famous dung beetle lives in Egypt and is 1~2.5 cm long. The largest dung beetle in the world is a giant dung beetle 1 cm long. Most dung beetles are dung eaters, feeding on animal dung, and have the title of "natural scavengers".

dung beetles usually feed on feces or humus, which plays an important role in the balance of ecosystem. The ecological value of dung beetles includes transferring feces to the ground, secondary spreading of seeds, pollination, control of pests and intermediate host of parasites, as well as the development and application prospect, important bionic significance and great theoretical significance of the dung beetles.
