The Johnson Jumping Spider does not build webs to catch its food. It seeks it out, wandering around until it happens upon a good prey item. These tiny spiders jump large distances (considering their size) to catch their prey. Olympic long jumpers have nothing on these little powerhouses. They are day-time hunters and hide out at night and in the winter.

They have been known to bite humans, but without serious effects. Females weave funnel-shaped webs to lay eggs in under rocks or between objects. Males have an abdomen that is completely red, whereas the female will have a black line down the center of her abdomen.
