The purpose of this study is to analyze the mechanism of a small insect's wing to make the micro machine which is able to move and fly everywhere in three dimensional area. We investigate the structure of small insects and take photographs of the insects, which are Aulacophora nigripennis and Harmonic axyridis, by using the high speed video camera. Then we obtained the locus of the wings, and the following three flapping parameters; the flapping angle, the period and the velocity. After all we reach the conclusions as follows; 1) The upper wing moves simulateneously with the wing. 2) The Aulacophora nigripennis and Harmonia axyridis have similar posture in flying. From these consequences, we know the mechanism which is suitable for the body size of small insects.
