|Bees like playing with balls, study finds
Everyone knows that bees are busy. There is even a saying in English that one can be "as busy as a bee". However, little is known about how bees play. Scientists have discovered one way that bees could relax after a busy day making honey - they play with balls. The scientists are from Queen Mary University of London. They did different tests on bees "playing" with different things. The insects particularly liked playing with small, wooden balls. The researchers said the way bees played was a little like how humans play. Younger bees rolled more balls than older bees, while adult males spent longer playing with balls than adult females. The ball-rolling bees are the first known insects to "play".
