最近的研究表明，甲虫的粘性鞑靼刚毛具有沿其长度方向的材料梯度。这些梯度可能代表了一种进化的最优化，增强了对粗糙表面的适应，同时防止了侧向塌陷导致的刚毛丛生。本研究的数值实验清楚地表明，与硬基上软尖较长的纤维和软基上硬尖的纤维相比，具有短软尖和硬基的梯度承重纤维在多个附着-分离循环中在最大限度地提高附着力和最大限度地减少簇化方面具有更大的优势。这项研究不仅显示了在甲虫纤维粘连系统中沿刚毛方向的材料特性的关键作用，而且预测在节肢动物的不同谱系中肯定已经收敛地进化出类似的梯度。
It has been recently demonstrated that adhesive tarsal setae of beetles possess material gradients along their length. These gradients presumably represent an evolutionary optimization enhancing the adaptation to rough surfaces while simultaneously preventing clusterisation of the setae by lateral collapse. The numerical experiment of the present study has clearly demonstrated that gradient-bearing fibers with short soft tips and stiff bases have greater advantage in maximizing adhesion and minimizing clusterisation in multiple attachment–detachment cycles, if compared to the fibers with longer soft tips on the stiff bases and fibers with stiff tips on the soft bases. This study not only manifests the crucial role of gradients in material properties along the setae in beetle fibrillar adhesive system, but predicts that similar gradients must have been convergently evolved in various lineages of arthropods.
