Dung beetle Ecology and behavior
 Dung beetles eat dung of herbivores and omnivores, and prefer that produced by herbivores. Many of them also feed on mushrooms and rotting leaves and fruits. One type living in South America, 'Deltochilum valgum', is a carnivore eating millipedes. Those that eat dung do not need to eat or drink anything else, because the dung provides all the necessary nutrients.
