The webs are oriented vertically and have a "signal" thread attached to the center that notifies the spider when prey has been captured. 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 ...
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", [ 1 ] hence the English name of the group.
The orb part of the web may be nearly 2 feet (0.61 m) in diameter. [5] The eggsac consists of fluffy yellow threads in a rolled leaf over a lenticular or spherical egg mass 5–12 mm (0.20–0.47 in) in diameter, which may contain up to 1,000 eggs. Juveniles are frequently preyed upon by mud daubers. [6]

In the latter case, Araneus trifolium is sometimes confused with the orange orb weaver species Araneus marmoreus, also called pumpkin spider. The shamrock spider can be ...
