Unlike Argiope garden spiders, Araneus marmoreus hides in a silken retreat to the side of the web (at the end of the signal thread). The retreat can be made from leaves folded over and held together with silk ...
Spiders of this genus present perhaps the most obvious case of sexual dimorphism among all of the orb-weaver family, with males being normally 1 ⁄ 3 to 1 ⁄ 4 the size of females.
