蜜蜂飞行速度的视觉控制通过训练他们在一个特别建造的隧道中飞行，在这个隧道中，墙壁上的图案的运动，对比和纹理都可以变化。图案运动的操纵揭示了飞行的速度是通过调节眼睛所经历的图像运动来控制的。飞行速度对视觉环境的对比度和/或空间纹理的变化具有令人惊讶的鲁棒性，这表明潜在的运动检测机制在很大程度上独立于这些参数来估计眼睛中的图像运动的速度。这确保了飞行速度主要取决于到附近表面的距离，而不是取决于它们的特定视觉特性，例如对比度或视觉纹理。图像运动线索的去除大大损害了飞行速度的调节，强调了它们在这一功能中的作用。
Visual control of flight speed in honeybees (Apis mellifera L.) was investigated by training them to fly through a specially constructed tunnel in which the motion, contrast and texture of the patterns lining the walls could be varied. Manipulation of pattern motion revealed that the speed of flight is controlled by regulating the image motion that is experienced by the eyes. Flight speed is surprisingly robust to changes in the contrast and/or spatial texture of the visual environment, suggesting that the underlying movement-detecting mechanisms estimate the speed of image motion in the eye largely independently of these parameters. This ensures that flight speed depends primarily on the distances to nearby surfaces and not upon their particular visual properties, such as contrast or visual texture. The removal of image motion cues drastically compromises the regulation of flight speed, underscoring their role in this function.
