Polistes sulcifer 是一种杜鹃纸黄蜂，是一种专性社会寄生虫，必须侵占另一个物种的群体才能繁殖。现场数据显示，雌性 P. sulcifer 侵占了仅属于一种物种（P. dominulus）的巢穴。此外，它们更常见于大型且富含蛹的巢穴。一系列实验室试验为雌性寄生虫提供了具有不同特征的巢穴的二元选择，证实了 P. sulcifer 和 P. dominulus 之间的物种特异性，以及寄生虫对侵占含有蛹的较大巢穴的偏好。这些数据支持这样的假设：雌性苏西弗在可用的巢穴之间进行选择。讨论了这些发现的生物学意义。
Polistes sulcifer is a cuckoo paper wasps, an obligate social parasite which must usurp a colony of another species in order to reproduce. Field data show that P. sulcifer females usurp exclusively nests belonging to one species only (P. dominulus). Moreover, they are more frequently found on large and pupa-rich nests. A series of laboratory trials, in which parasite females were offered a binary choice of nests with different characteristics, confirm both the species specificity between P. sulcifer and P. dominulus and the parasite's preference to usurp larger nests containing pupae. The data support the hypothesis that P. sulcifer females choose between available nests. The biological meaning of these findings is discussed.
