When dung beetles sniff out a fresh pile of manure, they shape a small ball out of it and push it away to a safe distance where they can eat it in peace, away from other competing insects. They like to run in straight lines, so they don’t accidentally change course and turn back towards the dung pile where another beetle will try to steal its precious ball. How do they get their bearings? Scientists have discovered that they navigate via the Milky Way! Tiny, poo-eating insects are down in the dirt but also have their eyes on the stars.
