Dung beetles are beetles that feed partly or exclusively on feces (dung). A dung beetle can bury dung 250 times heavier than itself in one night.[1]
Many dung beetles, known as rollers, roll dung into round balls, which are used as a food source or breeding chambers. Others, known as tunnelers, bury the dung wherever they find it. A third group, the dwellers, neither roll nor burrow: they simply live in manure. They are often attracted by the dung collected by burrowing owls. There are dung beetle species of different colours and sizes, and some functional traits such as body mass (or biomass) and leg length can have high levels of variability.[2]
All the species belong to the superfamily Scarabaeoidea; most of them to the subfamilies Scarabaeinae and Aphodiinae of the family Scarabaeidae (scarab beetles). As most species of Scarabaeinae feed exclusively on feces, that subfamily is often dubbed true dung beetles. There are dung-feeding beetles which belong to other families, such as the Geotrupidae (the earth-boring dung beetle). The Scarabaeinae alone comprises more than 5,000 species.[3]
The nocturnal African dung beetle Scarabaeus satyrus is the only known non-vertebrate animal to navigate and orient itself using the Milky Way.[4][5]
"Darwin was the first to use data from nature to convince people that evolution is true, and his idea of natural selection was truly novel. It testifies to his genius that the concept of natural theology, accepted by most educated Westerners before 1859, was vanquished within only a few years by a single five-hundred-page book. On the Origin of Species turned the mysteries of life's diversity from mythology into genuine science." -- Jerry Coyne
