Dung beetles. A pretty humble creature - albeit one sacred to some cultures because their rolled balls of dung resemble the sun.
And they always roll their balls in a straight line. During the day, presumably, they use the sun. At night...the moon? But what when there's no moon...

This is the only known instance (so far) of insects using stellar navigation. Pretty cool little guys.
