Unidentified

Thanks for giving the ID an attempt, I appreciate it when people try. She’s Araneus marmoreus, a Marbled Orbweaver. https://bugguide.net/node/view/2016 The link goes to Bugguide’s display of some of the markings and colors variations in this species. Yours looks different because she has already oviposited her eggs into an egg sac. Her abdomen is shrunken from dehydration and having been very stretched. The key to recognition of this species Vs. other Orb Weavers is the pattern of the color bands on the legs. Starting proximal (close to the body) they usually go in the pattern of: red/white/red/white/ black/ white/black.
