蜻蜓（包括豆娘）是一种色彩鲜艳、眼睛大的昆虫，具有显着的性二态性、颜色转变和颜色多态性。最近全面的视觉转录组学揭示了蜻蜓谱系中视蛋白基因的非凡多样性。这些视蛋白基因的差异表达之间的水生幼虫和陆生成人，以及成人复眼的背侧和腹侧区域。最近的主题颜色形成的蜻蜓也概述。非虹彩蓝色是由来自准有序纳米结构的相干光散射引起的，而虹彩颜色是由多层结构产生的。皱纹或蜡晶有时会增强多层结构色。红蜻蜓的性别特异性和阶段特异性颜色差异归因于色素的氧化还原状态。
Dragonflies including damselflies are colorful and large-eyed insects, which show remarkable sexual dimorphism, color transition, and color polymorphism. Recent comprehensive visual transcriptomics has unveiled an extraordinary diversity of opsin genes within the lineage of dragonflies. These opsin genes are differentially expressed between aquatic larvae and terrestrial adults, as well as between dorsal and ventral regions of adult compound eyes. Recent topics of color formation in dragonflies are also outlined. Non-iridescent blue color is caused by coherent light scattering from the quasiordered nanostructures, whereas iridescent color is produced by multilayer structures. Wrinkles or wax crystals sometimes enhances multilayer structural colors. Sex-specific and stage specific color differences in red dragonflies is attributed to redox states of ommochrome pigments.
