Ball-rolling dung beetles are insects of the family Scarabaeidae that locate animal dung by smell and use it for food and reproduction, a process that supports nutrient cycling and soil health across many ecosystems. They have robust, rounded bodies and specialised legs designed for sculpting and rolling large spheres of animal waste across open terrain. Unlike nocturnal species that rely on the moon, moonlit sky gradients, patterns of polarised light, stars, and even the Milky Way for orientation, ball-rolling dung beetles that are active during the day use the sun and polarised light in the sky to maintain a straight course as they roll away from competitors.
