This distinctive spider is often noticed because of its large size and its habit of building webs in gardens and grassy areas near houses. It is most typically found in tall grasslands.
The small cephalothorax is tipped with silver hairs, and the slightly oval abdomen is patterned yellow (sometimes orange) and black. A black mid-stripe with four white spots in the center marks the top of the abdomen. The legs are black with yellow-orange stripes. The upper portion of the legs is more solidly colored orange-yellow. Females are much larger than males and can reach lengths of 19-28mm as compared to 5-8mm for males.
This spider can be found sitting head-down at its web's hub where a zig-zag silk band, the stabilimentum, extends vertically from the center. A variety of insects may fall prey to this spider, especially grasshoppers and katydids. Certain species of smaller spiders use yellow garden spider webs as their own and may feed on the tiny insects caught in the web.
Missouri distribution: presumed statewide in tall grasslands with tall herbaceous vegetation.
