我们以前已经证明，蜜蜂利用绿色（或L-）受体介导的亮度视觉来探测远距离的目标。他们探测到的圆形目标，对于l受体来说，有一个暗淡的中心和明亮的环绕，距离比有明亮中心和暗淡环绕的目标要远。在这里，我们展示了大多数蜜蜂授粉的花都有一个中心，对于l受体来说，这个中心是暗淡的，周围是明亮的，也就是说，它们的图案很容易被蜜蜂发现。l受体周围暗淡的花往往比周围明亮的花大，这表明花通过增加其显示的大小来补偿其图案的可见性受损。
We have demonstrated previously that honeybees use brightness vision mediated by green (or L-) receptor to detect targets from a long distance. They detect circular targets having a dim, for the L-receptor, centre and bright surround from a longer distance than targets having bright centre and dim surround. Here we show that a majority of bee-pollinated flowers have a centre that, for the L-receptor, is dim with bright surround, i.e. have patterns that are easy for a bee to detect. Flowers with dim for the L-receptor surrounds tend to be larger than those with bright surrounds, indicating that flowers compensate for the impaired visibility of their patterns by increasing the size of their displays.
