This study reveals the influence of the phase difference between flapping and pitching motions on the aerodynamic performance of dragonfly tandem wings during hovering. By using a realistic three-dimensional wing model and observed hovering kinematics, the results demonstrate that a 90° phase difference provides more favorable aerodynamic characteristics for stable hovering flight.
