The flight of a bee

Michael Dickinson and his colleagues filmed hovering bees at 6000 frames per second, and plotted the unusual pattern of wing beats. The wing sweeps back in a 90˚ arc, then flips over as it returns – an incredible 230 times a second. The team made a robot to scale to measure the forces involved.
