The bumblebee, Bombus flavifrons, forages randomly with respect to direction on Polemonium foliosissimum. This foraging pattern is as predicted for a system where there is a low probability of revisiting any given flower upon returning to a patch. This low revisitation probability is a function of the floral resource arrangement. It is further shown that B. flavifrons is using the resource distribution to direct its movements. A large percentage of all movements are to nearest neighbors with maximal foraging efficiency gained through minimization of flight distances.
大黄蜂（Bombus flavifrons）在多叶花葱（Polemonium foliosissimum）上觅食时方向随机。这种觅食模式正如对这样一个系统的预测：回到一片花丛时再次光顾任何一朵特定花朵的概率较低。这种低再次光顾概率是花卉资源分布的一个函数。进一步研究表明，黄脸大黄蜂利用资源分布来指导其行动。所有行动中有很大比例是朝着最近的邻居移动，通过最小化飞行距离获得了最大觅食效率。
