This study is concerned with air damping effect in passive pitching motion of insect flapping wing, which will be based on the Fluid-Structure Interaction (FSI). Thus, we evaluated it using three-dimensional numerical analyses for the FSI based on the finite element method. From the numerical analysis, we found that the air damping leads the mode of wing's natural vibration from underdamping to overdamping so as to form the characteristic pitching motion.
