Spider Dance

This lovely lady is hanging around my front porch, and at night she does the "O boy I caught a MOTH!" dance for me. She's an absolute delight to watch.

I can't be certain as to species, but does look like she's an orb weaver of either the Araneus or the Nuctenea genus.

After checking with the very knowledgeable , it appears that the lady may rather be an Eriophora edax. The Google images that come up for this species are closer in color and shape than in the previous genii. ...Man, I am going to have to get myself some better spider field guides!
