As usual, UF is here to rescue me with so much info about the Saddleback Caterpillar:

I showed them to my family so they would know what they look like and not to touch. My brother said it looked like it had a wrapper on it before I could tell him the name. It made me think how common names are very much a product of their times. If we hadn't discovered them until recently, they might be the Candy Wrapper Caterpillar. Sounds a lot nicer to me!
