Insects, earthworms, fungi and bacteria form the key decomposers of the Savanna biome. Brett Ratcliffe, a dung beetle expert at the University of Nebraska in Lincoln, said the research provides insight to the foraging behavior of the many species of dung beetles that are active during the night.

The ‘Dwellers’ neither roll nor burrow, but simply live in the manure wherever they find it. Humans wear polarized sunglasses, for example while fishing, to filter out the glare from polarized light that is reflected off the water's surface. And we probably can extrapolate to certain other insects that navigate at night. This specific type of beetle specializes in the decomposition of 'dung' (poop). Polarized light patterns cast directly by the sun and indirectly from the sun's reflection off the moon are invisible to the human eye, but can be seen by a host of others in the animal kingdom.
