离开蜂巢后，觅食蜂携带少量蜂蜜，随后消耗蜂蜜以产生飞行能量。我们调查了摇摆阶段的持续时间和作物体积之间的关系，在觅食（舞蹈演员和舞蹈追随者）离开蜂巢。我们的研究结果表明，这些变量在两种类型的蜜蜂中呈正相关，这表明它们能够根据与食物源的距离来调整它们携带的食物量。我们还发现，跟着跳舞的蜜蜂比跟着跳舞的蜜蜂带着更多的蜂蜜离开蜂巢。我们提出了两种可能的解释：（1）舞蹈追随者对食物来源的位置的信息比舞蹈者少，舞蹈者对周围地区有更好的了解;或者（2）蜜蜂缺乏精确的校准方法来估计摇摆运行时间的能量需求。觅食经验的影响得到了证实：蜜蜂在出发时通过重复前往糖浆喂食器减少了蜂蜜负载。当喂食器提供大豆粉作为花粉替代品时，蜜蜂表现出不同的变化模式，这可能是因为蜜蜂不仅将蜂蜜用作能量来源，而且还将其用作“胶水”，以在后腿上形成花粉“球”。根据我们的观察，糖浆觅食者的追随者携带不同数量的蜂蜜在他们的作物比大豆追随者的追随者，我们建议摇摆舞者也传达有关食物类型的信息。
Upon leaving the hive, foragers carry a small amount of honey, which they subsequently consume to generate energy for flight. We investigated the relationship between waggle-phase duration and crop volume in foragers (both dancers and dance followers) leaving the hive. Our findings indicate that these variables were positively correlated in the two types of bee, suggesting that they were able to adjust the amount of food that they carry depending on the distance to a food source. We also found that dance followers left the hive with a larger amount of honey than dancers. We suggest two possible explanations: (1) dance followers have less information about the location of the food source than dancers, who have a better knowledge of the surrounding area; or (2) honeybees lack a precise calibration method for estimating energy needs from waggle-run duration. The effect of foraging experience was confirmed: bees decreased their honey load at departure with repeated trips to a sugar-syrup feeder. Honeybees showed a different pattern of change when the feeder provided soybean flour as a pollen substitute, possibly because honeybees use honey not only as an energy source but also as "glue" to form "balls" of pollen on their hind legs. Based on our observations that followers of sugar-syrup foragers carry a different amount of honey in their crop than followers of soybean-followers, we suggest that waggle dancers also convey information concerning food type.
