The duration of interaction events in a society is a fundamental measure of its collective nature and potentially reflects variability in individual behavior. Here we performed a high-throughput measurement of trophallaxis and face-to-face event durations experienced by a colony of honeybees over their entire lifetimes. The interaction time distribution is heavy-tailed, as previously reported for human face-to-face interactions. We developed a theory of pair interactions that takes into account individual variability and predicts the scaling behavior for both bee and extant human datasets. The individual variability of worker honeybees was nonzero but less than that of humans, possibly reflecting their greater genetic relatedness. Our work shows how individual differences can lead to universal patterns of behavior that transcend species and specific mechanisms for social interactions.
社会中互动事件的持续时间是其集体性质的基本衡量标准，并且可能反映了个体行为的可变性。在这里，我们对一个蜜蜂群体在其整个生命周期中经历的营养交换和面对面事件的持续时间进行了高通量的测量。与之前报道的人类面对面互动一样，交互时间分布呈重尾分布。我们开发了一种考虑个体可变性的对相互作用的理论，并预测了蜜蜂和现存人类数据集的标度行为。工蜂的个体可变性不为零，但小于人类的个体可变性，这可能反映了它们更高的遗传相关性。我们的工作表明，个体差异如何导致超越物种的行为的普遍模式，以及社会互动的具体机制。
