男性的侵略性是高度可变的亚社会蜘蛛螨，发生在整个日本的人口。侵略性的平均水平是正相关的平均冬季温度和相对大小之间的男性腿我，这是用来作为武器在这个物种。巢内雄性的亲缘关系受越冬存活率的影响，高存活率导致低亲缘关系，增加攻击性，和更大的腿。因此，在这个物种中，性选择强度的变化可能同时受到自然选择和亲缘选择的影响。
Male aggressiveness is highly variable among populations of a subsocial spider mite that occurs throughout Japan. The average level of aggressiveness is positively correlated with mean winter temperature and with the relative size among males of leg I, which is used as a weapon in this species. The relatedness of males within nests is influenced by rates of overwinter survival, with high survivorship leading to low relatedness, increased aggressiveness, and larger legs I. Within this species, variation in the intensity of sexual selection may therefore be influenced both by natural selection and by kin selection.
