Fruit flies (Drosophila and its close relatives, or “drosophilids”) are a group that includes an important model organism, Drosophila melanogaster , and also very diverse species distributed worldwide. Many of these species have black or brown pigmentation patterns on their wings, and have been used as material for evo‐devo research. Pigmentation patterns are thought to have evolved rapidly compared with body plans or body shapes; hence they are advantageous model systems for studying evolutionary gains of traits and parallel evolution. Various groups of drosophilids, including genus Idiomyia (Hawaiian Drosophila ), have a variety of pigmentations, ranging from simple black pigmentations around crossveins to a single antero‐distal spot and a more complex mottled pattern. Pigmentation patterns are sometimes obviously used for sexual displays; however, in some cases they may have other functions. The process of wing formation in Drosophila , the general mechanism of pigmentation formation, and the transport of substances necessary for pigmentation, including melanin precursors, through wing veins are summarized here. Lastly, the evolution of the expression of genes regulating pigmentation patterns, the role of cis ‐regulatory regions, and the conditions required for the evolutionary emergence of pigmentation patterns are discussed. Future prospects for research on the evolution of wing pigmentation pattern formation in drosophilids are presented, particularly from the point of view of how they compare with other studies of the evolution of new traits.

果蝇翅膀色素沉着的演变：多样性，生理调节和顺式调节演变。

果蝇（果蝇及其近亲，或称“果蝇”）是一组重要的模式生物，果蝇（Drosophila melanogaster），还分布在世界各地。这些物种中许多都在其翅膀上有黑色或棕色的色素沉着图案，并已被用作进化研究的材料。色素沉着模式被认为与人体计划或身体形状相比发展迅速；因此，它们是研究特质和平行进化的进化增益的有利模型系统。不同种类的果蝇，包括Idiomyia属（夏威夷果蝇）），有各种色素沉着，从十字纹周围的简单黑色色素沉着到单个前后角斑点和更复杂的斑驳图案。色素沉着模式有时显然用于性爱展示。但是，在某些情况下，它们可能具有其他功能。果蝇的机翼形成过程，色素沉着形成的一般机制以及色素沉着所需的物质（包括黑色素前体）通过机翼静脉的运输在此进行了概述。最后，调节色素沉着模式的基因表达的演变，顺式作用讨论了调节区域以及色素沉着模式进化出现所需的条件。提出了研究果蝇中机翼色素沉着模式形成演变的未来前景，特别是从它们如何与其他新特性进化研究比较的角度出发。
