It is an Orb Weaver (Neoscona crucifera). It is found from Maine to Florida in the east, to Minnesota in the Midwest, to Arizona in the southwest, and in Mexico.
Females are about 9.5–19 millimeters (0.37–0.75 in) long, while males are somewhat smaller. The upper surface of the abdomen is brown and hairy. The legs display alternating light and dark brown bands. The undersurface of the abdomen is black, with two white spots.
This species is relatively variable in color and sometimes pattern, but is most commonly seen sporting a rusty-red or golden orange color. The orb-shaped web is very large and is often constructed on buildings and other man-made structures, especially near outdoor lights. This species is most conspicuous in late summer and early fall.
For many years, this kind of orb spider would build a very large web every night just outside the back door (near a light.) While fascinating to watch, if was a lot less fascinating to forget it was there in the morning and walk face first into it. But I prefer to live and let live, so... :)
