Most species of spiders leave their egg-sacs in a sheltered place. However, some of them look after or carry their egg-sacs until the spiderlings hatch. Others extend their maternal behaviour to feeding their young by regurgitation or by the distribution of prey. The adaptative aspect of this maternal behaviour is shown by a reduced rate of reproduction in the species whose care of progeny is the most sophisticated. The maternal care of the egg-sac depends on the physiological state of the female, that state, in turn, being maintained by the presence of the egg-sac. The tolerance exhibited by the mother towards her offspring implies at least two mechanisms: (i) inhibition of predatory behaviour in response to the movements of an offspring at a distance, (ii) inhibition of cannibalism when in contact with an offspring. The parental relationship can be complemented by cooperation between the young that involves a tolerance mechanism probably close to that of social spiders.
大多数蜘蛛种类会将卵囊置于隐蔽之处。然而，其中一些蜘蛛会照看或携带卵囊，直至幼蛛孵化。还有一些蜘蛛会将母性行为扩展至通过反刍或分发猎物来喂养幼蛛。这种母性行为的适应性体现在对后代照料最为精细的物种繁殖率降低。对卵囊的母性照料取决于雌蛛的生理状态，而这种状态又由卵囊的存在得以维持。母亲对后代表现出的容忍至少意味着两种机制：(i) 对远处后代移动做出反应时抑制捕食行为，(ii) 与后代接触时抑制同类相食。亲子关系可通过幼蛛之间的合作得到补充，这种合作涉及一种可能与群居蜘蛛的容忍机制相近的机制。
