Dragonfly perform very advanced flight. It is caused by the difference in partial stiffness of the wing elasiticity. Therefore, we pay attention to the partial stiffness of the dragonfly's wing. Numerical simulation based on the finite difference method is employed to investigate the influence of the wing elasiticity. The theory is suggested by the elasiticity of the cylinder as the equivalent of the real elasiticity of the dragonfly's wing. However, it is undestood that the elasiticity by a suggested theory was different from the real elasiticity of the dragonfly's wing. So, we performed a elasiticity measurement by the new measurement method to investigate the real elasiticity of the wing.
