Bees have two pairs of wings and three pairs of feet. Its front wings are big and its rear wings are small. If a pair of wings are cut off by humans, it will continue to fly, but if one of them is cut off, it will soon fall off. Bees fly not only by wings, but also by legs. The hind legs will stretch forward to help it fly, and the rising power of the hind legs can help it keep its balance. But under special circumstances, when two pairs of wings are cut off, it will "fly", that is, when the wings are cut off, the worker bee will fly with the queen bee on its back. They belong to Insecta.
