摘　　要：Detailed investigations on the microstructure and mechanical properties of the surface of the praying mantis'foreleg were carried out in this work since the microstructure and mechanical properties of insect organisms surfaceare well adjusted to their functions.Scanning electron microscopy revealed the surface microstructures of the tibia andfemur were composed of squamous fibre and the spine surfaces on these two parts are arris.A nanoindenter wasused to investigate the mechanical properties of the praying mantis's foreleg,including the mean Young's modulusand hardness of the femur cuticle,tibia cuticle and the apical claw.The test results on these parts were E=5.533 GPa,H=0.239 GPa,E=3.471GPa,H=0.186 GPa,E=2.232GPa,H=0.449 GPa,respectively.The variation of mechanicalproperties agreed with the analysis of microstructure.
