摘要研究了昼行蝶科蝶科、蛱蝶科、蛱蝶科和蛱蝶科成员的气管绒毡层的三维结构、反射特性和眼光色调。从结构和生理上的差异可以区分两大类绒毡体。在梨形昆虫中，横纹肌底部的主要气管干在更远处分叉之前分成两个侧分支，而在研究的蛱蝶科、蛱蝶科和Lycaenidae的成员中，气管干首先分成四个侧分支。在第一次分叉后不久，第二次分叉产生八个亚分支，它们有规律地排列在相邻的受体细胞之间。从偶然照射的绒毡结构（在第一分岔的水平）反射的宽带状颜色在不同的家族和家族内部有所不同，但在同一只眼睛内没有显著变化。然而，在雌雄虫、雌雄石虫和lycaenids中，眼睛发光的颜色与绒毡反射的颜色相对应，在pierids中，它是由彩色受体筛选色素主导的。
Abstract The three-dimensional structure of the tracheal tapetum lucidum, its reflection properties and the resulting eye glow hue were studied in members of the diurnal butterfly families Pieridae, Nymphalidae, Satyridae and Lycaenidae. Two main groups of tapeta can be distinguished by structural and physiological differences. Whereas in pierids the main tracheal trunk at the bottom of the rhabdom bifurcates into two side branches before bifurcating again more distally, the tracheal trunk in the members of the family Nymphalidae, Satyridae and Lycaenidae investigated first divides into four side brandies. A second bifurcation shortly after the first results in eight subbranches which are regularly arranged between adjoining receptor cells. The broad banded reflection colour from incidently illuminated tapetal structures (at the level of the first bifurcation) varies between and within families but does not change significantly within the same eye. Whereas in nymphalids, satyrids and lycaenids the eye glow hue corresponds with the colour of the tapetal reflection, in pierids it is dominated by the coloured receptor screening pigment.
