复活节蛋象鼻虫，属Pachyrhynchus（鞘翅目，象鼻虫科），辉煌的外观，起源于复杂的介电纳米结构内的鞘翅鳞片和鞘翅。以前的工作，研究奇异成员的Pachyrhynchus显示存在准有序或有序的三维光子晶体基于单钻石（）对称性在其尺度。然而，很少有人知道的多样性的结构着色机制的家庭。在这里，Pachyrhynchus的光学性质进行了研究，系统地确定其光谱和结构特征。四个主要特征，改变他们的外观和这些特征的进化历史，以确定生态趋势重建。结果表明，整个复活节蛋象鼻虫的着色机制是不同的，高度可塑性的密切相关的物种与功能出现在多个独立的时间在其整个生育期。这项工作为更好地理解节肢动物体内各种形式的准有序和有序金刚石光子晶体奠定了基础。
The brilliant appearance of Easter Egg weevils, genusPachyrhynchus(Coleoptera, Curculionidae), originates from complex dielectric nanostructures within their elytral scales and elytra. Previous work, investigating singular members of thePachyrhynchusshowed the presence of either quasi‐ordered or ordered 3D photonic crystals based on the single diamond () symmetry in their scales. However, little is known about the diversity of the structural coloration mechanisms within the family. Here, the optical properties withinPachyrhynchusare investigated by systematically identifying their spectral and structural characteristics. Four principal traits that vary their appearance are identified and the evolutionary history of these traits to identify ecological trends are reconstructed. The results indicate that the coloration mechanisms across the Easter Egg weevils are diverse and highly plastic across closely related species with features appearing at multiple independent times across their phylogeny. This work lays a foundation for a better understanding of the various forms of quasi‐ordered and ordered diamond photonic crystal within arthropods.
