Hickory Tussock Moths (Lophocampa caryae) are native to northeastern North America down to North Carolina and a few even wander to Texas and down into Mexico. These photos are their larvae, their caterpillars.
Hickory Tussock Moths have just one generation per year. Eggs are laid in clusters of 100 or beyond, on the undersides of the leaves of their preferred trees, Hickory, Walnut, Pecan, and American Hornbeam but other trees are chosen as well. These young caterpillars feed together as a “crew” skeletonizing the leaves. To see these caterpillars at work is startling but usually they don’t do enough damage to permanently harm a tree.
The more mature caterpillars are around in late summer into autumn. They measure to about 1.75 inches and develop into solitary creatures.
Looking cute and cuddly, white with black (those black tufts are called “pencils”). But be wise. Don’t pick them up. Their little barbed hairs can cause irritation on your skin. Panda Bears of the insect world — don’t touch.
I am always on the alert for turtles in the road and if conditions allow, I’ll stop and help the critter, usually a box turtle, cross safely. A few days ago as I drove up my mountain, along the twisty, steep, gravel road, I spotted something. Certainly not a turtle, but something I don’t recall ever stopping for in the past. Something that I never would have guessed I’d see from the driver’s seat of my truck. A HUGE caterpillar. My surprise only increased as I approached the caterpillar and saw what it looked like. Certainly he was a Chinese dragon all set for a New Year’s parade.
An aqua color of 1950s cars, with accents of bright, rich orange, and black. Regularly spaced black spikes along his body segments and much larger spiked horns/antlers of orange, tipped with black near his head. Yes, that looks like a Chinese dragon to me.
In reality though this critter is a Hickory Horned Devil Caterpillar, the larva of the Regal Moth, Citheronia regalis. In addition to his interesting color scheme, this guy is incredibly large. Think the size of a large hot dog. But it is a caterpillar that you don’t need to be frightened of. He will cause you no harm. If you see one, treat him with care, and guide him to a spot of soft dirt where he can achieve his goal of burrowing, where he will pupate over the winter.
Spiked horns on two segments above his head (his head is the little orange, button-like thing at the very right), bright, rich orange, and shiny black.
In this stage of his life he has been eating. Chomping down on the leaves of hickory, ash, persimmon, sweetgum, sycamore and walnut. No wonder he made his home here. This is what many of the trees in my woods are. No need to be concerned about what he is eating. There are not enough of these guys to be a concern and for the most part are not considered a pest. The Hickory Horned Devil is native to the eastern US from New Jersey to Missouri and on southward to east Texas and central Florida.
The Regal Moth will emerge from the ground as an adult in late June or early July. As an adult he will not eat, and will live about one week.
He will reach a wingspan of up to six inches. Looking like a cuddly, furry, off white and orange Teddy bear, he will be in search of a mate. Eggs hatch in six to ten days. The larval stage, the Hickory Horned Devil Caterpillar, lives for about 35 days.
