The elytra of jewel beetle, which are metallic green with red stripes, have been used as an ornament from ancient times because of their colorful colors, light mass and high strength. In particular, the elytra of jewel beetle have more than 15 layered structures, making them easy to reflect a lot of light, so they have a structural coloration that looks different in color depending on the angle of view. Investigation of this ingenious structure is very interesting topic not only for the arts and cultural heritage conservation, but also for the researchers who want to apply it to biomimicry. In this study, surface analytical instruments such as AFM and nano-indenter were used to investigate structural and mechanical properties of elytra. The surface morphology and phase, lateral force, and surface potential were measured by AFM. The cross sectioned samples of two different color areas (green and red) by FIB and also measured by AFM. And the hardness and thickness of the multilayer were verified with nano-indenter.
