During the rainy season in Africa, a herd of buffalo can create thousands of pounds of waste in a day, which would be an environmental disaster if not for the dung beetle. These extraordinary insects depend on waste to survive. They eat it, attract mates with it, and raise families in it. Although dung beetles are critical to the ecosystem, they don't have it easy. Every day, they must avoid being trampled, evade predators like bullfrogs, honey badgers, and rock monitor lizards, and rival dung beetle families desperate for the same fecal prize.
