dying soon after mating since they are rarely collected past early summer. Adult females have been collected through early fall. Egg sacs have been observed through September, with later egg sacs containing fewer eggs/spiderlings. It is not known whether the later egg sacs are repeat layings by the same female. Females have been observed moving their egg sac around their web, carrying it under their abdomens, especially when disturbed. Spiderlings molt once in the egg sac prior to emerging as second instars. The fifth instar is the adult stage. References 2003. Guide d'identification des Araignées (Araneae) du Québec.
