This poor little guy couldn't find his way out of my house. I left the window open for him and eventually he did. He was about 8 feet up the wall. I originally thought it was a Monarch, but upon enlarging the photos, I didn't think so after all.
I think it is a Lycorea cleobaea (or L. halia), common names Tiger Mimic-Queen or Large Tiger. They are attracted to papaya trees.
If you are interested in identifying the butterflies that you see, Discover Life has a great page where you input the colors and distinctive markings and it gives you a list of possibilities. I was able to find this one in two minutes.
