觅食蜜蜂在采集环境样本和做出觅食决策时所采用的时间和空间尺度既取决于大黄蜂的记忆极限，也取决于生境中奖励的时空模式。我们分析了以前实验的数据，以确定大黄蜂最近的觅食经历如何影响它们到后续花朵的飞行距离。对一朵花的一次访问足以影响到下一朵花的飞行距离。然而，较长的两次或三次访问序列对单个觅食者随后的飞行距离有额外的影响。这表明，大黄蜂可以从至少三朵花中整合信息，以做出随后的觅食决定。至少在这个尺度上，花特征记忆的存在可能对自然环境中的花选择具有重要意义。
The temporal and spatial scales employed by foraging bees in sampling their environment and making foraging decisions should depend both on the limits of bumble bee memory and on the spatial and temporal pattern of rewards in the habitat. We analyzed data from previous experiments to determine how recent foraging experience by bumble bees affects their flight distances to subsequent flowers. A single visit to a flower was sufficient to affect the flight distance to the next flower. However, longer sequences of two or three visits had an additional effect on the subsequent flight distance of individual foragers. This suggests that bumble bees can integrate information from at least three flowers for making a subsequent foraging decision. The existence of memory for floral characteristics at least at this scale may have significance for floral selection in natural environments.
