Abstract
Copulating males usually insert their penis into the female and ejaculate in her reproductive tract; but in some species, males are more invasive, puncturing the female body-wall and inseminating directly into her body-cavity. A spider has just been added to this list and new perspectives provided on why males harm females during copulation in the first place.
摘要
正在交配的雄性通常会将阴茎插入雌性体内，并在其生殖道内射精；但在某些物种中，雄性的行为更具侵入性，会刺穿雌性的体壁并直接在其体腔内授精。一种蜘蛛刚刚被列入这一名单，并且对于雄性为何在交配时伤害雌性这一问题也有了新的见解。
