This is one of the most widely distributed jumpers in the US, and commonly referred to as the ‘Bold Jumping Spider’.  Males reach 6-13mm, and females 9-18mm.  The one below was found in my house, climbing on the walls.  Immediately when put into a jar with two crickets, she hunted and consumed them both within a few hours, and her girth doubled.  This one has particularly nice blue chelicera.
