Hi there.

I'd like some help ID'ing a spider that I found at the edge of my covered porch this afternoon. It wasn't there last night.

I live in central Oklahoma, if that helps. Oh, and it might be hard to tell, but the spider is quite large. I'd say the body is about the size of the first joint on my thumb (if that makes sense).

The last picture isn't a great one of the spider, but you can see the web really well, so I thought that might help too.

Thanks in advance!
