本文用一种改进的大数值孔径物镜透镜落射照明装置，观察了大量小眼蝶的眼睛发光。本文介绍了几个典型的例子：山羊Bicyclus anynana，Heliconian Heliconius melpomene，小白色粉蝶Pieris raepiece和小铜Lycaena phlaeas。眼睛光泽的颜色主要取决于绒毡层反射镜的反射光谱和光感受器屏蔽色素的透射光谱，如果存在于光导感杆附近的话。反射光谱测量从个人小眼显示，绒毡层和筛选色素共同表达在固定的组合，从而确定不同的小眼类。类分布在一个不规则的图案，可以快速评估与新颖的落射照明装置。许多蝴蝶物种似乎都有反射红色的小眼，这被解释为表明存在红色敏感的光感受器。
The eye shine of butterflies from a large number of ommatidia was observed with a modified epi-illumination apparatus equipped with an objective lens of large numerical aperture. A few representative cases are presented: the satyrine Bicyclus anynana, the heliconian Heliconius melpomene, the small white Pieris rapae and the small copper Lycaena phlaeas. The colour of the eye shine is determined mainly by the reflectance spectrum of the tapetal mirror and the transmittance spectrum of the photoreceptor screening pigments, if present near the light-guiding rhabdom. Reflectance spectra measured from individual ommatidia show that tapetum and screening pigments are co-expressed in fixed combinations, thus determining different ommatidial classes. The classes are distributed in an irregular pattern that can be rapidly assessed with the novel epi-illumination apparatus. Many butterfly species appear to have red-reflecting ommatidia, which is interpreted to indicate the presence of red-sensitive photoreceptors.
