Watching dung beetles in the bush is like watching morning commuters at New York's Grand Central: they always seem to be in a hurry and not even obstacles deter them from getting where they need to be. Today I discovered dung beetles might be a little more sophisticated than I realized when I read this BBC article. Apparently these insects use the Milky Way (more specifically, polarized light) to orientate themselves on Earth. This helps them to roll their food (a ball of animal dung) in the shortest path possible to their home - a straight line.
P.S. Did you know dung beetles can move over 1,000 times their body weight? For more info on dung beetles and their behavior, I found this TED Talk here.
