磷球虫苍蝇在金龟子粪甲虫身上交配，跟随它们进入地下，并在收集到的粪便中产卵。我们发现，雄蝇和雌蝇在甲虫身上的分布不是随机的，它们的种群大小也不同。处女的比例随着种群大小的增加而增加，成熟卵的雌性最常出现在携带较少苍蝇的甲虫身上。实验室实验表明，交配的雌性避免更大的群体，处女似乎更喜欢大群体，而交配的雌性更喜欢小群体。雄性没有表现出这样的模式。这些结果表明，北极熊可以估计种群的大小，这可能是一种具有生殖功能的适应。然而，苍蝇并不是基于已经安装的苍蝇的性别而加入宿主的。
The phoretic sphaerocerid fly Norrbomia frigipennis mates on scarabid dung beetles, follows them underground, and lays eggs in the collected dung. We found that male and female flies distribute themselves nonrandomly on beetles with respect to fly group size. The proportion of virgin females increased with group size, and females with mature eggs were most frequently found on beetles carrying fewer flies. Laboratory experiments revealed that mated females avoided larger groups, virgin females seemed to prefer large groups and mated females, small groups. Males showed no such pattern. These results suggest that N. frigipennis can estimate group size, presumably an adaptation with a reproductive function. However, flies did not join hosts on the basis of the sex of already mounted flies.
