The spines on the side of this female spider make it unique and easy to recognize. Males are considerably smaller than females and they lack the spines. There are a variety of species in this genus and colors vary.
Like other orb weavers, it creates a web that is circular in shape, only it has few or no spirals at the center of its web. Each night, a new web is spun to catch small insect prey. The spider stands up-side-down on the web.
Late in the year, the female will lay eggs that will grow throughout winter, hatching spiderlings in the spring. The oval-shaped egg sac is near the web, usually hidden underneath leaves. It may be white, green or yellowish, but it is woven of the spider's silk.
