Dung Beetle
Scarabaeus sacer
Quick answer
Dung beetles are beetles that feed on animal droppings, and many are famous for rolling dung into balls and pushing them away to bury as food or a brood chamber. They are remarkably strong for their size and play a vital role in recycling waste, improving soil, and reducing pests. Found on every continent except Antarctica, dung beetles include species that roll, tunnel, or simply dwell in dung.

Rollers, tunnelers, and dwellers
Dung beetles use dung in different ways depending on the species. Rollers shape dung into balls and push them away to bury, tunnelers dig down beneath a dung pat to store it, and dwellers simply live within the dung itself. The rolling species are the most famous, navigating in straight lines sometimes using the sun, the moon, or even the band of the Milky Way.
Remarkable strength
Dung beetles are among the strongest animals for their size. Some species can pull loads many hundreds of times their own body weight, the equivalent of a person hauling several loaded trucks. This strength helps them move dung balls far larger and heavier than themselves across uneven ground.
Diet and reproduction
Both adults and larvae feed on dung, which provides nutrients and moisture. Many species form a brood ball in which the female lays an egg, so the hatching larva has a ready food supply. By burying dung, the beetles also plant it underground where it nourishes the soil.
Ecological importance
By burying and consuming dung, dung beetles recycle nutrients, improve soil structure, and reduce the breeding grounds of pest flies and parasites that thrive in droppings. They also help disperse seeds contained in dung. These services make them valuable to farmers and to natural grassland ecosystems worldwide.
Frequently asked questions about the Dung Beetle
Why do dung beetles roll dung?
Rolling species shape dung into balls and push them away to bury as a food store or as a brood chamber for their eggs. Moving the dung away reduces competition from other beetles at the original pile.
How strong are dung beetles?
Dung beetles are among the strongest animals relative to their size, with some species able to pull many hundreds of times their own body weight. This lets them move dung balls far heavier than themselves.
What do dung beetles eat?
Dung beetles feed on animal droppings, which provide both nutrients and moisture. Both the adults and their larvae rely on dung as their main food source.
Are dung beetles useful?
Yes. By burying dung they recycle nutrients, improve soil, disperse seeds, and reduce pest flies and parasites. These services make them valuable to farming and natural ecosystems.
How do dung beetles navigate?
Rolling dung beetles move in straight lines using cues such as the position of the sun or moon, and some can even orient by the band of the Milky Way. This keeps them from circling back to the dung pile.
Where do dung beetles live?
Dung beetles are found on every continent except Antarctica, in habitats ranging from grasslands and farmland to forests and deserts. They live wherever grazing animals leave droppings to feed on.
