The nanostructures on the wings of (Moore, 1877) were analysed using scanning electron microscopy, energy dispersive X-ray spectroscopy, atomic force microscopy, Fourier transform-infrared spectroscopy, and reflectance measurements. The chemical and morphological analyses revealed the chitin-based intricate nanostructures. The influence of the nanostructures on the wetting characteristics of the wing was investigated using optical imaging. Applying the Maxwell-Garnet approximation to the porosities within the nanostructures, the refractive indices, which relate the reflectance response, were estimated. It was concluded that the colour seen on the wings of the originate from the nanostructural configurations of the chitin-based structures and the embedded pigment.
使用扫描电子显微镜、能量色散X射线光谱仪、原子力显微镜、傅里叶变换红外光谱仪和反射率测量对（摩尔，1877年）翅膀上的纳米结构进行了分析。化学和形态学分析揭示了基于几丁质的复杂纳米结构。使用光学成像研究了纳米结构对翅膀润湿特性的影响。将麦克斯韦-加尼特近似应用于纳米结构内的孔隙率，估算了与反射率响应相关的折射率。得出的结论是，在翅膀上看到的颜色源于基于几丁质的结构和嵌入色素的纳米结构配置。
