Bold Jumping Spider

A common jumping spider of North America. The average size of adults ranges from roughly 13 to 20 mm in length. These spiders are typically black with a pattern of spots and striped on their abdomen and legs. Often these spots are orange-tinted in juveniles, turning white as the spider matures. These spiders have been known to jump up to 50 times their own body length by suddenly increasing the blood pressure in the third or fourth pair of legs, and the male may jump away during mating if the female approaches too quickly. They are excellent at nabbing flies!
