looks like one of the many species of jumping spiders to me.

Jumping Spiders, also known as?
Naphys pulex, (North American Jumping Spider) may be the easiest to recognize.?The Jumping Spider is the largest family of spiders with around 13% of all species.?They have rectangular faces and a very distinctive, flat-faced, big-eyed appearance that is difficult to confuse with other kinds of spiders. They also have a unique, herky-jerky way of moving. Most are small and hairy. Like all spiders, jumping spiders have 8 legs, 2 body parts, and no antennae. Eight eyes are present on jumping spiders, although 1 pair is often so small that it appears as though there are only 6 eyes. One pair of eyes is always very large and directed forward, almost like human eyes. They are known to have some of the best vision and tend to make use of it in their hunting, navigation and courting. Typically, these spiders move slowly and silently, they are quite capable of sprightly jumps, particularly when hunting but also in response to unexpected danger.
Jumping Spiders are active hunters. This spider has a well-developed internal hydraulic system that assists in extending their limbs by adjusting the pressure of body fluid within them. That means the spiders can jump without buiding muscular legs like grasshoppers, which allows them to jump many times the length of their body.When they move from one location to another, and more so when they jump, it releases and fastens a thin strand of silk to the place they're standing to protect them should they fall or they can climb back up to safety. Their diet is primarly carnivorous but they also include nector in their diet.
Jumping spiders use their vision in complex visual courtship displays. Males use their differences from females--plumose hairs, colored or iridescent hairs and other, often bizarre, modifications. If the female is receptive, she will assume a passive, crouching position. Jumping Spiders hatch from eggs and look like tiny adults when they are born. They shed their skin as they grow. Many female jumping spiders construct a silk case for their eggs and guard them until they hatch. The egg case is often built off of the ground in leaves, on branches, or in crevices on the sides of buildings.
