Hickory Horned Devil
When I was a boy, I always hoped to find one of these amazing creatures munching on the leaves of the hickory trees in our neighborhood. I never did, though -- they are not all that common, and live mostly in the South. My bad luck to live in the North! The hickory horned devil is likely the largest, and certainly the fiercest-looking, caterpillar in North America. Full-grown, they are nearly half a foot long, and will rear up and make a clicking sound if you bother them. They're totally harmless, though, like pretty much all caterpillars.
The hickory horned devil turns into the regal moth, a gigantic, beautiful animal that most people will never see in nature.
