Butterflies

I dragged my family to the zoo today. It was a last minute thing. I love the zoo in the summer because of the butterfly house. I don't know the name of this butterfly. They had a guide posted of the types of butterflies in the house, but this doesn't look like a monarch to you, does it? Anyway, I love the chance to get close to these types of insects. LOL. let me know what kind of butterfly you think this is.
