I found this spider in a web on our back porch around dusk today. It seemed to be very teritorail of its web. I knocked it down with a broom, and if fell to the ground of the first floor, about an hour later it was back at its web. Starting closest to the body and then going out was red, then light yellow, then back. Im just curious to know what kind of spider it is because I have seen more then one on my back porch, and I know that down here in Louisiana, you have to watch out for black and brown widow spiders.
