Video: Raising Hickory Horned Devil Caterpillars

Please enjoy this live stream video of these amazing caterpillars in the subfamily of giant silk moths, Ceratocampinae. In a group referred to as royal moths, the “Hickory Horned Devil” caterpillar, Citheronia regalis, is one of the most dramatic-looking caterpillars on earth! Each molt, known as an “instar,” presents a brand new look to this very intimidating but harmless caterpillar. If not for it’s appearance, its size is enough to frighten a predator — or a human! This amazing caterpillar turns into a spectacular reddish moth known as the Royal Walnut Moth with a wingspan of almost 7 inches.

Update on the Hickory Horned Devil Caterpillars:

This is the last day for these caterpillars. They are ready to go down underground to become pupae, a sleeping stage that lasts through the winter. In late spring, they will emerge to become the magnificent Royal Walnut Moth, a red patterned moth with a wingspan of almost 7 inches!

I love learning about art, music, science, and history. I attended Tyler School of Art (Temple University) in the 1970s, and then spent many years as a prototype sculptor for the fine gift industry. Recently I went back to college and graduated in 2025 with a Bachelor of Science degree in Liberal Arts from Northern Arizona University. Now I look forward to teaching art and sharing music, with the goal to inspire others to recognize their talents and realize their dreams.
