Regular three-dimensional periodic structures have been observed in the scales of over half a dozen butterfly species. We compare several of these structures: we calculate their photonic bandgap properties; measure the angular variation of the reflection spectra; and relate the observed iridescence (or its suppression) to the structures. We compare the mechanisms for iridescence suppression in different species and conclude with some speculations about form, function, development and evolution.
在六种以上蝴蝶物种的鳞片中观察到了规则的三维周期性结构。我们比较了其中几种结构:计算它们的光子带隙特性;测量反射光谱的角度变化;并将观察到的虹彩(或其抑制)与这些结构联系起来。我们比较了不同物种中虹彩抑制的机制,并以对形态、功能、发育和进化的一些推测作为结论。
