In result years, Micro-Air-Vehicles (MAVs) and micro-flight robot that mimic the flight mechanisims of insects have been attracting significant attention. However, these robots were not practical. One of the reasons for this is that the flying mechanism of insects has not yet been clarified sufficiently. The purpose of the present study is to clarify the dynamic behavior and the detailed structure of the vortices of the flapping butterfly wing. A vortex ring is formed over the wings of the butterfly. The vortex ring develops over the wings when the wings flap downward to the bottom dead position, and passes through the butterfly at the bottom dead position. When the wings flap upward to top dead position, the vortex ring passes through the butterfly wings completely and grows up to the wake.
