In this project the PIs will study wing colors in butterflies. The brilliant colors found on the wings of butterflies have attracted attention from biologists and physicists alike. Many of these colors are due to light interacting with the nano-structures on the surface of the wing scales. In particular the aim of this project is to focus on a group of closely related species that have remarkably different colors, and have a known evolutionary history. This will allow the PIs to examine the smallest amounts of morphological change in a scale's structure that can produce a change in color. The PIs will combine descriptive and theoretical approaches coupled to experimental methods to fully understand how structural colors are produced in this group of butterflies. They will pursue two main approaches: The first approach will involve a comparison of wing scale color and associated morphology across the butterfly genus Bicyclus. The second approach will target a change in scale color using artificial selection in replicate lines of Bicyclus anynana butterflies, and describe the associated morphological changes in the nano-structure of the scales. The PIs will train graduate and undergraduate students, many of them women, as well as actively participating in a variety of outreach activities that are aimed at the broader public. One of the PIs will participate in established Yale education outreach programs to local high schools and middle schools. The PIs will also produce an interactive web-based animation showing how diverse structural colors evolved in a close group of butterflies, and disseminate the results from their findings broadly.

在这个项目中，PI 将研究蝴蝶翅膀的颜色。蝴蝶翅膀上的绚丽色彩引起了生物学家和物理学家的关注。其中许多颜色是由于光与翅膀鳞片表面的纳米结构相互作用而产生的。该项目的具体目标是关注一组密切相关的物种，这些物种具有明显不同的颜色，并且具有已知的进化历史。这将使 PI 能够检查鳞片结构中可能产生颜色变化的最小量的形态变化。 PI 将结合描述性和理论方法以及实验方法，以充分了解这组蝴蝶的结构颜色是如何产生的。他们将采用两种主要方法：第一种方法将涉及双环蝴蝶属翅膀鳞片颜色和相关形态的比较。第二种方法将针对双环蝴蝶复制系中的人工选择来改变鳞片颜色，并描述鳞片纳米结构的相关形态变化。 PI 将培训研究生和本科生（其中许多是女性），并积极参与针对更广泛公众的各种外展活动。其中一名 PI 将参加耶鲁大学为当地高中和初中设立的教育推广计划。 PI 还将制作一个基于网络的交互式动画，展示不同的结构颜色如何在紧密的蝴蝶群中进化，并广泛传播他们的发现结果。
