Identification
Online Description/Photos: The prosoma is pale yellow to yellow green, with a dark median stripe and often darker shading in the submarginal area. The opisthosoma has a white background, with yellow- to brown-shaded stripes on the lateral edges. A series of black dots often connect to make three lines longitudinally down the posterior, the midline reaching the farthest anteriorly. The ventral opisthosoma has two yellow spots just posterior of the epigastric furrow; a black area is between the epigastric furrow and the spinnerets. The spinnerets are usually dark. The legs are yellow to yellow green, with prominent spines. Femurs (sic) I and II have ventral dark lines.

Habitats and Life History
Habitats: fields, forest edges, roadsides and gardens.
Observation Methods: Visual observation, sweep netting.
Abundance/Frequency: Common
Silk / Web: Web is a fine meshed orb built horizontally or at an angle to the vertical, with a central "bullseye" stabilimentum in the center. Spider may remain in the web during the day. Purpose of center bullseye uncertain, camouflage for spider or it may attract UV light like those of Argiope.
Behavior: In October builds web at dawn orienting its web perpendicular to the rising sun, to warm up in its web quicker.
