Yes, It's Real!

Last year while I was doing a photo session in my "portrait park", I noticed something odd on the side of a walnut tree. It looked almost unreal, more like a cartoon character. I took several photos of it, as it crawled around on the tree. Upon doing some research on the internet, I found that it is the larva of a spicebush swallowtail butterfly! Yes, this thing turns into a butterfly.

Here's a link to a photo of the larva:

And here's a link to what it looks like once it changes:
