Dung beetles always roll along the Milky Way


Pushing a calm ball is her passion: dung beetles like to roll dung for their lives, at least during the mating season. Scientists have found that the Milky Way plays an important role in this. It helps the insects to orient themselves so that they can transport their balls straight from A to B.

Who would have thought that? Dung beetles are true stargazers and take advantage of the Milky Way, among other things, to roll their dung balls to his beloved as quickly as possible. After all, she wants to raise her children in it. As the "Stuttgarter Nachrichten" reports, a team of researchers from Sweden and South Africa has now found out how the six-legged friends manage to travel the almost straight and therefore shortest route from the dung heap - the Milky Way plays an important role here.

Rollin ', rollin', rollin '! Dung beetles reach for the stars

In a series of experiments, the scientists put the dung beetles in a test arena and let them roll their dung balls under a starry sky. As expected, it went straight to the edge. However, if you "bandaged" the insects' eyes so that no light came from above, they rolled in serpentine lines through the arena - and theoretically ran the risk of being stolen from them by a member of their species. In further experiments it turned out that the moon was used for orientation at night. Amazingly, the dung beetles also keep their course on new moon. The experiments showed that the Milky Way alone points the way to the warm nest.
