用电生理学方法研究了黑脉金斑蝶（Danaus plexippus）复眼光感受器的光谱、角度和偏振敏感性。细胞内记录揭示了一个光谱均匀的UV受体群体，光轴向上，与对侧成>= 10度。基于光学考虑和视蛋白表达模式（Sauman等人，2005），我们得出结论，这些UV受体属于眼睛的解剖学上特化的背缘区域（dorsal rim area，RRM）。对侧或同侧的具有< 10度光轴的主视网膜中的光感受器在UV（λ（max））中具有最大的敏感性。
The spectral, angular and polarization sensitivities of photoreceptors in the compound eye of the monarch butterfly (Danaus plexippus) are examined using electrophysiological methods. Intracellular recordings reveal a spectrally homogenous population of UV receptors with optical axes directed upwards and >= 10 degrees to the contralateral side. Based on optical considerations and on the opsin expression pattern (Sauman et al. 2005), we conclude that these UV receptors belong to the anatomically specialized dorsal rim area (DRA) of the eye. Photoreceptors in the main retina with optical axes < 10 degrees contralateral or ipsilateral have maximal sensitivities in the UV (lambda(max)
