Bold Jumping Spider

Bold Jumping Spider
When most people think of spiders they think of them sitting in a web catching flies, however not all spiders catch their prey using a web. Most members of the jumping spider family hunt their prey by first stalking it and then pouncing. There are over 5000 described species in the jumping spider family, which makes it the largest of the spider families. Jumping spider all have four pairs of eyes with especially large anterior median eyes, those on the front of their face. They have excellent eye sight which they use to locate their prey. After they sneak closer to the prey they will alter the increase the blood pressure in their back two pairs of legs which will launch them, 10 to 50 times their body length, at the prey. They are able to spin webs and do use them for egg laying. They may also use webbing to hide or for a lifeline when jumping. This is a bold jumping spider which is common through out most of the United States.

He has an interesting face. We have tiny black and white jumping spiders here that my children call zebra spiders.
