Insect attachment devices enhance adhesion to complex-geometry substrates by increasing the real contact area. In nature, insects mainly interact with plant surfaces that are often covered by 3D wax structures. Here, we describe, discuss, and give a mechanical interpretation of plant waxes and the possible fracture mechanisms of these wax structures during their interactions with the adhesive pads of insects. It is argued that these plant surface microstructures significantly influence insect adhesion through reducing the contact area and contaminating the insect pads.
昆虫附着装置通过增加实际接触面积来增强对复杂几何形状底物的附着力。在自然界中，昆虫主要与通常覆盖着三维蜡质结构的植物表面相互作用。在此，我们描述、讨论并对植物蜡质以及这些蜡质结构在与昆虫粘附垫相互作用过程中可能的断裂机制给出力学解释。有人认为，这些植物表面微观结构通过减小接触面积和污染昆虫粘附垫，对昆虫的附着力有显著影响。
