What kind of butterfly will this caterpillar turn into?

I found this caterpillar the other day. Its difficult to describe. It is about and inch and a half long. It has orange on its head.. right behind the orange on its head, it has brown on his neck area. then It's creme colored until it gets to the butt where there is a strip of brown under three orange dots. Its has a feather-looking thing that sticks out of its butt. It's either dark brown or black. It also has two feather-like things sticking out of its head like horns. The feather things are about one fourth inch long. It has a lot of long, light colored hairs sticking straight out all over its body. Any idea what kind of butterfly it will turn into? Thanks! :)
