Abstract Pseudopupil of the compound eye of the housefly was studied by the method of corneal neutralization, and the deep pseudopupil under antidromic illumination in situ. 摘要 在逆光照明下采用角膜中和及深伪瞳方法研究了蝇的在位复眼光学特性。
And while they might have fooled you, mantises and other insects and crustaceans have " pseudopupils."
虽然它们可能愚弄了你,但螳螂和其他昆虫以及甲壳类动物都有“伪瞳孔”。

Pseudopupil
In the compound eye of invertebrates such as insects and crustaceans, the pseudopupil appears as a dark spot which moves across the eye as the animal is rotated. This occurs because the ommatidia that one observes "head-on" (along their optical axes) absorb the incident light, while those to one side reflect it. The pseudopupil therefore reveals which ommatidia are aligned with the axis along which the observer is viewing.
