蝴蝶翅的反射率主要由入射光的非相干散射和翅色素在翅片结构中的吸收决定。在雄蝶的翅背或翅尖经常会遇到引起彩虹色的相干散射。采用氨水局部提取和同步分光光度法，研究了翼元素对翅膀反射率的影响。吸收紫外线的白蝶素主要从白色的穿孔燕中提取，吸收紫外线的黄蝶素和吸收蓝色的红蝶素主要从黄色和橙色的穿孔燕中提取，但也从许多雄性穿孔燕的背翅尖中提取。由翅膀反射光谱推导出的吸收光谱与提取色素的吸收光谱存在明显的差异，表明嵌入翅膀鳞片后的翼类与溶液中的翼类存在差异。讨论了蝶翼颜色的演变。(c) 2007 Elsevier Ltd.版权所有。
The reflectance of pierid butterfly wings is principally determined by the incoherent scattering of incident light and the absorption by pterin pigments in the scale structures. Coherent scattering causing iridescence is frequently encountered in the dorsal wings or wing tips of male pierids. We investigated the effect of the pterins on wing reflectance by local extraction of the pigments with aqueous ammonia and simultaneous spectrophotometric measurements. The ultraviolet-absorbing leucopterin was extracted prominently from the white Pieris species, and the violet-absorbing xanthopterin and blue-absorbing erythropterin were mainly derived from the yellow- and orangecolored Coliadinae, but they were also extracted from the dorsal wing tips of many male Pierinae. Absorption spectra deduced from wing reflectance spectra distinctly diverge from the absorption spectra of the extracted pigments, which indicate that when embedded in wing scales the pterins differ from those in solution. The evolution of pierid wing coloration is discussed. (c) 2007 Elsevier Ltd. All rights reserved.
