Using a high-speed computer vision system, we recorded the wing motion of tethered flying fruit flies for up to 12 000 consecutive wing strokes at a sampling rate of 6250 Hz. We then decomposed the joint motion pattern of both wings into components that had the minimal mutual information. In this way we identified 4 distinct patterns of wing stroke modulation that are under independent physiological control. Three of these modulations can be associated with the control of yaw torque, total flight force, and pitch torque, respectively. The fourth pattern consists in a fast modulation of the wing stroke with a periodicity of two stroke cycles
