We've previously shown you some examples of creepy moth larvae that look a thousand times more horrifying than their cuddly adult forms – and even some that can straight-up kill you – but most of them are small enough to appear less threatening... but that's not the case with the humongous larva of the regal moth (Citheronia regalis), which definitely earns its nickname “the horned devil.”

Citheronia regalis is fairly common across most of the southern US, and can usually be found in hickory and walnut trees. The orange-and-yellow adults are also among the largest of North American moths. Here's a clip showing the stages of the creature's life cycle:
Still not creepy enough for you? How about a caterpillar that can transform itself into a snake?
