Mate guarding - a male staying near a female for a while after mating - has traditionally been interpreted in the context of sexual conflict. New observations of wild field crickets suggest instead that guarding males provide protection from predators, enhancing female fitness.
求偶后伴护行为——雄性在交配后短时间内留在雌性身边——在传统上被解释为性冲突的一种表现。然而,对野生蟋蟀的新观察表明,求偶后的伴护雄性实际上为雌性提供了免受捕食者侵害的保护,从而提高了雌性的适应度。
