Manual mark-by-mark image analysis was used to quantify the number of individuals present in a Tetragonula carbonaria swarm. A total of 7328 bees were identified in the swarm. The distribution of individuals within the swarm followed a Gaussian distribution, with the distances to the nearest neighbour strongly positively skewed. The clustering of bees in the centre of the swarm is likely a mechanism for reducing predation risk. In the case of male mating swarms, large aggregations may increase the mating success of the species.

芒草四叶虫种群的定量和分布（膜翅目：ida科）

手动逐个标记的图像分析用于量化四角纲碳carbon群中个体的数量。蜂群中共鉴定出7328只蜜蜂。群内个体的分布遵循高斯分布，与最近邻居的距离强烈正偏。蜂群聚集在蜂群的中央可能是降低捕食风险的一种机制。在雄性交配群的情况下，大的聚集可能会增加该物种的交配成功率。
