After viewing the butterflies in your site, this appears to be a Common Buckeye. I like the coloring on this one, I found interesting reading on how the eye on the butterfly is a light lavendar when fresh, and changes eventually. Some appear quite different in color. This butterfly landed on my friends young daughter in Bella Vista Arkansas. I was fortunate to see the Butterfly migration this year in southern california. The sky was filled with them for a few days going over the house.
We just had someone write in with a caterpillar ID and it was a Common Buckeye. Next day he sent in the new Chrysalis and now you have completed the metamorphosis for us.
