摘要：

Males of the staphylinid beetle Ontholestes cingulatus remain close by their mates following copulation while the mated females oviposit. The hypothesis that male behavior constitutes adaptive mate-guarding was tested by examining three predictions: (1) receptive females would be scarce, (2) some females would mate multiply, and (3) males that stayed with their mates would often be able to repel rivals intent on takeovers. All three predictions were confirmed. These results and additional comparative evidence suggest that postcopulatory associations have evolved in the Staphylinidae only when the reproductive costs of this form of mate-guarding are outweighted by its benefits.
