Distribution in North Carolina
Comments: Overwinters as a subadult and matures early for such a large spider. In the coastal plain matures by April or May, in the mountains early June or July. Usually any extremely large web encountered at this time of year in the forests of the Carolinas is this species, because the golden silk and marbled orbweavers are active as adults in the fall.

Habitats and Life History
Habitats: forest openings
Observation Methods: When not in web they may be encountered on lichen covered trees or green vegetation. Shaking the web or telegraph line can sometimes draw the female out.
Abundance/Frequency: Uncommon throughout the state and eastern United States.
Silk / Web: Large orb, 3-4 feet in diameter.
Predators: Two kleptoparasitic scorpionflies, Panorpa rufescens Rambur (Mecoptera: Panorpidae), were observed stealing food from Araneus bicentenarius (McCook) (Araneae: Araneidae) at Waterboro Barrens Preserve, York County, Maine. The spider's ensnared prey was a larva of Lapara sp. (Lepidoptera: Sphingidae), which provided food for both spider and kleptoparasites.
Behavior: At night this spider builds a large orb web 3-4' in diameter hiding in a leaf retreat throughout the day with a telegraph line to feel for prey.
