The beetles navigated best when exposed to a clear starry sky, but managed equally well when only the diffuse band of the Milky Way Galaxy was visible. These beetles roll a ball of dung for some distance from where it was deposited, and bury it, excavating an underground chamber to house it. Copris hispanus in excavated chamber - Scarabaeus satyrus is one of the dung beetle species. It is undoubted that many other animals make use of similar techniques, some frogs, bats, moths and spiders being likely candidates. To ensure that they were not using cues on the horizon, they were placed in a container with blackened walls. It was their ability to stay on course on clear moonless nights that puzzled researchers. Vertebrates such as humans, birds and seals are known to navigate in this way, but this could be the first insect found to do the same.

. An egg is then laid in the ball, the growing larva feeding on the dung, pupating, and eventually emerging as an adult. Previous experiments showed that these beetles are able to steer by light from the Sun, the Moon, and polarised light emanating from these light sources. Beetles were taken into the where the appearance of the apparent sky could be controlled. . .
