The purpose of this study is to clarify the dragonfly's aerodynamic characteristics. The dragonflies have excellent flight ability such as high-speed flight and hovering flight. But we can't design the flying machine like dragonflies according to conventional laws of aerodynamics. The flying law is very difficult to understand because it is coupled problem about flutter motion, surface structure and elastic deformation of the wings. So we characterize an aerodynamics by visualization experiment. In this paper, we investigated the aerodynamic characteristic of the surface structure of the wings. Dragonflies have characteristic surface structures of the wings such as nervure and reticulation. We made the artificial wings imitated their surface structures, and the characteristics were clarified by the experiment.
