The Phidippus audax is often called the Daring Jumping Spider or Bold Jumping Spider. It is a common jumping spider in North America. It is among the largest of the jumping spiders. Adults grow to be between 1/2 inch and 3/4 of an inch. They are usually black with white stripes and spots as adults. As juveniles they sometimes have an orange tint to them. Their mouths are iridescent green in color. They can jump 10 to 50 times their body length by increasing the blood flow to their third and fourth legs. They have eight eyes total. Four eyes are forward facing. Two of the four are very large and the other two are slightly smaller. The other four eyes are on top of its head. The Daring Jumping Spider can see better than most other spiders. Unlike a lot of other spiders, the Daring Jumping Spider does not catch its prey in a web, but rather stalks and jumps on it. They do, however, use silk threads to line their burrows and to break their fall when jumping far distances. They are not poisonous to humans unless the human is allergic. They usually do not try and bite, choosing to flee from the vicinity rather than attack.
