Female dimorphic jumping spiders are about 6.5 to 8 mm long with a light brown carapace and pale legs, while males are smaller at 4.75 to 6.5 mm and have carapaces ranging from light to dark brown with a dark edge. Two male colour forms exist: a “tufted” type that is all black with white legs and three bristle tufts on the front cephalothorax, and a “gray” type that shows black-white stripes, a white stripe on the front eyes, striped legs, bright orange pedipalps and no tufts. These spiders are often found on fences, outbuildings and other man-made structures throughout southeastern Canada and the eastern United States.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
