女性更喜欢那些对自己有直接和/或间接好处的男性特征。男性之间的竞争也推动了代表竞争能力的男性特征的进化。由于雌性选择和雄性竞争很少独立作用，探索这两种机制如何相互作用对于综合理解性选择特征的进化是必要的。在这里，我们关注的是雄性吸引力、求偶和武器角色对雌性的直接和间接的好处。雄性用它们的后腿与其他雄性争夺领地，并为成功交配而求爱。与有吸引力的雄性交配并不能给雌性带来直接的好处。另一方面，我们发现雄性吸引力、求偶率和武器大小具有显著的遗传变异，并且雄性吸引力与求偶率和武器特征都具有正的遗传协方差。因此，雌性通过生育求爱成功率高、竞争能力强的儿子，与有吸引力的雄性交配获得间接利益。此外，求偶率和后腿长度显然是雌性选择的评价线索。因此，雌性的择偶和雄性的竞争可能是相互促进的。这与当前性选择的基本概念是一致的。
Females prefer male traits that are associated with direct and/or indirect benefits to themselves. Male–male competition also drives evolution of male traits that represent competitive ability. Because female choice and male–male competition rarely act independently, exploring how these two mechanisms interact is necessary for integrative understanding of the evolution of sexually selected traits. Here, we focused on direct and indirect benefits to females from male attractiveness, courtship, and weapon characters in the armed bug Riptortus pedestris. The males use their hind legs to fight other males over territory and perform courtship displays for successful copulation. Females of R. pedestris receive no direct benefit from mating with attractive males. On the other hand, we found that male attractiveness, courtship rate, and weapon size were significantly heritable and that male attractiveness had positive genetic covariances with both courtship rate and weapon traits. Thus, females obtain indirect benefits from mating with attractive males by producing sons with high courtship success rates and high competitive ability. Moreover, it is evident that courtship rate and hind leg length act as evaluative cues of female choice. Therefore, female mate choice and male–male competition may facilitate each other in R. pedestris. This is consistent with current basic concepts of sexual selection.
