Flower patterns are thought to influence foraging decisions of insect pollinators. However, the resolution of insect compound eyes is poor. Insects perceive flower patterns only from short distances when they initiate landings or search for reward on the flower. From further away flower displays jointly form larger-sized patterns within the visual scene that will guide the insect's flight. Chromatic and achromatic cues in such patterns may help insects to find, approach and learn rewarded locations in a flower patch, bringing them close enough to individual flowers. Flight trajectories and the spatial resolution of chromatic and achromatic vision in insects determine the effectiveness of floral displays, and both need to be considered in studies of plant-pollinator communication.
人们认为花朵图案会影响昆虫传粉者的觅食决策。然而，昆虫复眼的分辨率较低。昆虫只有在开始降落或在花朵上寻找花蜜时，才能从近距离感知花朵图案。从更远的距离看，花丛在视觉场景中共同形成更大尺寸的图案，引导昆虫飞行。这些图案中的色彩和非色彩线索可能有助于昆虫在花丛中找到、接近并记住有花蜜的位置，使它们足够靠近单朵花。昆虫的飞行轨迹以及其色彩和非色彩视觉的空间分辨率决定了花卉展示的效果，在植物-传粉者交流的研究中，这两者都需要考虑。
