Construction of a safe refuge is the first step toward the evolution of social organization in spiders. In the case of the subsocial spider Amaurobius Jerox (Araneae, Amaurobiidae), the young remain in the natal nest after consuming their mother's body (matriphagy). The benefit that the young could obtain from the maternal web was investigated in their collective prey capture. The results demonstrated the adaptive value of the maternal web. The prey capturing activity was more effective when the young were allowed to stay on the maternal web than when they used the web constructed by themselves. Maternal web may also provide a better transmission of information on prey state and clutch mates' activities, because more spiderlings were recruited to contact and hold the prey in a shorter period of time than when they were on a spiderling-constructed web. The young's inheritance of the maternal nest is probably one of the crucial ways in which the mother influences the post-maternal social period of the young.
构建安全庇护所是蜘蛛社会组织进化的第一步。对于亚社会性蜘蛛耶氏暗蛛(蜘蛛目,暗蛛科)而言,幼蛛在吃掉母亲的身体(母食性)后仍留在出生地的巢穴中。研究人员在幼蛛集体捕食过程中探究了它们能从母蛛的蛛网上获得的益处。结果证明了母蛛蛛网的适应性价值。与使用自己构建的蛛网时相比,幼蛛待在母蛛的蛛网上时捕食活动更有效。母蛛的蛛网或许还能更好地传递有关猎物状态和同窝伙伴活动的信息,因为与在幼蛛自己构建的蛛网上相比,在母蛛的蛛网上有更多幼蛛在更短时间内被吸引去接触并抓住猎物。幼蛛继承母巢可能是母亲影响幼蛛产后社会阶段的关键方式之一。
