Abstract: Research findings of the forewing structure of beetles and the development prospects of biomimetic applications were reviewed in this paper. The forewing is of frame structure with small columns as void lamination,and the coupling area of the left and right forewings is of the concave-convex meshing structure. The honeycomb-columniation structure , which exists in the forewing, is a kind of lightweight sandwich plate structure. The fibersbetween the columniation and the upper and lower layers of laminated composite material are continuous , which could effectively enhance the anti-stripping strength of the laminated composite materials. Special biological structures exist in the forewing surface of some beetles , leading to its special properties, such as drag-reduction, water capturing, and color development. A novel idea for producing biomimetic materials was proposed by designing vital genes.
