Papilio butterflies' ability to forage for flowers relies upon multiple visual cues such as color, brightness, and motion. Papilio learns the color of rewarding flowers and detects it at a distance. Its color vision is based on four photoreceptor classes: UV, blue, green, and red, providing sensitive wavelength discrimination. These four receptor classes also contribute to the perception of brightness and polarization. Papilio's motion vision is based on a different set of receptors: green, red, and broad band. This implies that two visual pathways exist in Papilio. The contribution of several receptor classes not only for chromatic vision but also achromatic vision likely enhances the butterfly's ability to detect flowers in complex visual environments.
凤蝶觅食花朵的能力依赖于多种视觉线索，如颜色、亮度和运动。凤蝶学习奖励花朵的颜色，并能远距离检测到它。它的颜色视觉基于四类光感受器：紫外线、蓝色、绿色和红色，提供敏感的波长辨别。这四类光感受器也有助于感知亮度和偏振。凤蝶的运动视觉基于一组不同的感受器：绿色、红色和宽带。这意味着在凤蝶中存在两种视觉通路。不仅对色觉，而且对非色觉而言，几种感受器类别的贡献可能增强了蝴蝶在复杂视觉环境中检测花朵的能力。
