We investigated unsteady aerodynamics of a hovering honeybee by a biology-inspired flight dynamic simulator. This simulator was developed to be able to 'fly' an insect on a basis of realistic wing-body morphologies and kinematics. A wing-body geometric and kinematic model was built based on the measurement data of real honeybee. The computed results indicated that as a high-lift generation was predicted during middle downstroke, an attachment of leading-edge vortex (LEV) was observed. At the same time, a break-down of the LEV was also observed at position of approximately 80% of wing length from the wing root. Therefore the hovering honeybee employs the LEV lift-enhance mechanism, which is similar to that of large- and small-size of flapping-flying insects.
