许多社会性昆虫物种采用定向招募食物的方式，以看似不必要的不精确性来传达目标的位置。在这里，我们提出的证据表明，蜜蜂的舞蹈通信的空间精度已被“调整”的选择，使新兵既不是那么准确，他们通常会发现已经耗尽的地区，也不是那么不准确，他们通常无法找到广告的资源。首先，蜜蜂的距离误差与它们的方向误差的大小相似，它们的角度误差随着到目标的距离的增加而大大减小（在100到700米之间减小四倍以上）。结果，新兵的绝对散布随着到目标的距离的变化而保持相对恒定（在100和700 m之间增加不到50%）。如果距离和方向的最佳不精确度水平相同，并且不随目标与巢的距离而变化，则这是可以预期的。第二，对三种热带和一种温带物种（都是蜜蜂）的比较研究表明，蜜蜂语言的精确性可能是根据每个物种使用的资源的空间特征而调整的。我们认为，无论是圆舞，它传达了附近的目标，并没有方向信息，在摇摆舞指示目标在几百米的殖民地的高角度发散都是可以理解的，在这种情况下。
Many social insect species that employ directional recruitment to food finds communicate the location of their targets with seemingly needless imprecision. Here we present evidence that the spatial precision of the honey bees' dance communication has been "tuned" by selection so that recruits are neither so accurate that they usually find areas which have already been depleted nor so inaccurate that they usually fail to find the advertised resources altogether. First, the bees' distance errors are similar in magnitude to their directional errors, and their angular errors decrease greatly with increasing distance to the target (decreasing more than fourfold between 100 and 700 m). As a result, the absolute scatter of recruits remains relatively constant with changing distance to the target (increasing by less than 50% between 100 and 700 m). This is to be expected if the optimal level of imprecision is the same for distance and direction and does not change with the distance of the target from the nest. Second, comparative studies involving three tropical- and one temperature-zone species (all Apis) suggest that the precision of the bees' languages may have been tuned in accordance with the spatial characteristics of the resources each species uses. We suggest that both the round dance, which conveys no directional information for nearby targets, and the high angular divergence in waggle dances indicating targets within several hundred meters of the colony are both understandable in this context.
