The collision dynamics of a water droplet on a wing surface of live dragonfly were studied using a high-speed video camera system. The high-speed video camera system is composed of two video cameras, two video cassette recorders, motion grabber, two video monitors, and a personal computer. This experimental study focused mainly on the function of the dragonfly wings for the droplet collision. The dynamic response of dragonfly wing was studied for two impact velocities of water droplet. It was found that live dragonfly wings have excellent shock absorption and deformability for the rain droplet collision.
