Little Two Faces  
This spider I call "Little Two Faces", found living in a rock in my sun porch in McGregor, Iowa. I took the pictures and then put her outside last Year, 2014. I wish now I would have kept her.

Answer
Jean Marie:

I can say for certain that your lovely spider is an orbweaver, family Araneidae, and I'm pretty certain it is the "Humpbacked Orbweaver," Eustala anastera .  Here's more about it:

There are records of it in Iowa, too.  Thank you for sharing your lovely images!
