Abstract�� As its unique morphological features (broad wings with small aspect ratio, complex wing shape), and the distinctive kinematics (low flapping frequency, the stroke plane is nearly perpendicular to the body; no wing rotating, but obviously body pitching and oscillating as wing flapping), butterfly fly is a special research subject in exploring insect high lift mechanisms. In order to take in-depth insight into the bio-fluid mechanics and the high lift mechanisms of butterfly hovering fly, it is necessary to design and manufacture an electromechanical model of flapping butterfly to simulate the flapping modes of the butterfly.A new designed electromechanical model of flapping butterfly which had the wings and the body just like the real butterfly was introduced. The electromechanical model can fix positions and simulate different flapping modes of the butterfly, including the wings- flapping and body-s rotation and up-down-oscillating movement. So it is useable for the experiments of flow visualization and particle image velocimetry(PIV).
