Habitats and Life History
Habitats: Coniferous or deciduous forest as well as open habitats.
Observation Methods: Visual observation.
Abundance/Frequency: Fairly common
Silk / Web: Large orb web, often with a retreat in a curled leaf at its upper edge.
Behavior: Web is built in low bushes, tall grasses or low branches of a tree. The retreat can easily be found near an upper corner of the web. During the day the spider waits in the retreat and holds a telegraph line connected to hub. On cloudy days, at dusk and all night it may be found hanging at the hub. The appearance of large orange females, preparing to lay eggs, observed on or near the ground near the end of October is the source of the nickname "Halloween spider".
