The unsteady three dimensional flow around flying insects is so complex that current experimental visualizaiton or measurement methods can not fully capture. The vortical flow is formed closed to the wing surfaces and later shed into the wake. By applying the high speed schlieren photography with alcohol brushed on the wing, the complex flow structure on a free flying hawkmoth was visualized sucessfully.
