Entomology (Study of Bugs)/Spider Identification

This spider is an orb-weaver; brown widows, like black widows in my observations, spin messy but strong webs in areas below the knees and are without observable body hair. These orangy-colored spiders in your picture spin traditional webs way above the knees and grow even bigger than widows, especially their abdomens, with spiky hairs protruding from their legs unlike widows. I can put money on the fact that you will never see them inside your home. Please allow them to trap pests outside your home for you. Tap its butt with a twig and it will "freak" into a position as if it is going to pounce, then it will retrieve up to its hiding spot. Do this again the next evening and it will not produce the same reaction as it will recognize you and the action.
