Last summer a fearsome looking spider took up residence on one of my screens. It's an Argiope spider. They live till the weather cools, then die. They eat mosquitoes & grasshoppers which makes them beneficial here in Florida. They are shy & don't bite unless provoked. If they do bite it is at the most, no worse than a bee sting. The web they design is quite unique, with what appears to be a zipper woven down the center.
