In this study, we evaluated passive pitching motions and lift force during flapping flights of three diferent Dipteras using the dynamically scaled model. Since the wing and the surrounding fluid interact with each other, the dynamic similarity between the model and the insect flight was measured using not only the Reynolds and Strouhal numbers but also the mass and Cauchy numbers. Our model includes the plate spring to simulate the low torsional stiffness of the insect wing. Our model simulated the pitching motion similar to the actual insect and generated the enough force to lift the insect.
