Neoscona crucifera
This is the same spider I had a picture of on September 13. At least it’s the same species. I don’t actually know if it’s the same one, but it certainly could be. This time it is in the back yard with its web between the flower stalks of Verbena bonariensis. I find that to be a much better place for a spider than across the entrance to my house. I tried to get pictures of it from the other side but it wouldn’t let me get close enough. Also, I was shooting into the sun from that side, which was difficult.
