Traffic clogged roads, congested mobile phone networks ¿ supercomputers running day and night to find the best route for cars and information. But we know that they don¿t always get it right, despite being very powerful. Bees have to find routes between flowers every day when finding food, and without computer help. How do they choose which flowers to visit, and in what order? Bees don¿t just have to visit flowers, they have to remember which have the most nectar, and visit them without wasting energy flying the long way round. Their route may not be perfect, but we hope it will help us find good routes through complex networks more easily. We will look at how bees remember which flowers are good to visit from day-to-day, and how it learns the location of flowers and best order to visit them. We will also look at whether they always visit flowers in the same order they discovered them, and how landmarks help them to retrace their steps. Finally, we will look at how bees cope when the amount of nectar in flowers changes, or there are other bees feeding from the same flowers.

交通堵塞的道路，拥挤的移动的电话网络，超级计算机日夜运行，为汽车和信息找到最佳路线。但我们知道，他们并不总是得到正确的，尽管非常强大。蜜蜂每天在寻找食物的时候都要在花丛中寻找路线，而且没有电脑的帮助。他们如何选择参观哪些花，以什么顺序？蜜蜂不会他们不只是要去赏花，他们要记住哪种花的花蜜最多，而且不要浪费精力绕着圈子飞。他们的路由可能并不完美，但我们希望它能帮助我们更容易地通过复杂的网络找到好的路由。我们将看看蜜蜂如何记住哪些花是好的访问从一天到一天，以及它如何学习花的位置和最佳顺序访问他们。我们还将研究它们是否总是按照发现花朵的顺序访问花朵，以及地标如何帮助它们追溯它们的脚步。最后，我们将看看蜜蜂如何科普花中花蜜量的变化，或者有其他蜜蜂从同一朵花中取食。
