Female spider shaped like an arrowhead, with thick red points at the bottom and small red spines at the shoulders and at the sides. The back is usually yellow with spots. Cephalothorax (fused head and thorax) reddish, as are the legs. Male is similar, but smaller and lacking the spines. Builds a web for catching insects in open areas of woodlands. Rather sinister-looking, but harmless to humans.

Common throughout eastern North America. Occasionally seen in Wildwood.

Easily identified by the distinctive shape and color-scheme.  Arrowhead Spiders (Verrucosa arenata) are also shaped like arrowheads, but their arrows point away from their heads, they lack spines, and they prefer to sit in their webs with their heads up, rather than down.
