Dung beetles use stars for orientation!
Researchers gave dung beetles caps to block out light. An insect with a tiny brain and minimal computing power has become the first animal proven to use the Milky Way for orientation. Scientists from South Africa and Sweden have published findings showing the link between dung beetles and the spray of stars which comprises our galaxy. Although their eyes are too weak to distinguish individual constellations, dung beetles use the gradient of light to dark provided by the Milky Way to ensure they keep rolling their balls in a straight line and don't circle back to competitors at the dung pile. "The dung beetles don't care which direction they're going in; they just need to get away from the bun fight at the poo pile," said Professor Marcus Byrne from Wits University. The dung beetle is the first animal proven to use the Milky Way for orientation. Byrne and his team previously proved that dung beetles use the sun, the moon and polarised li...
