Hickory Horned Devil
Over the weekend my good friend Jeremy Martin came over with an exciting treat--a Hickory Horned Devil... the large caterpillar of the Regal Moth or the Royal Walnut Moth.
I had never seen the hickory horned devil, though I had known of the regal moth from insect manuals. Jeremy found this fascinating creature crossing a path at Prairie Oaks park west of Columbus, Ohio. He returned it to the park after allowing me to photograph these images.
The hickory horned devil in these photos measured around six inches in length. From what I've read online, the appearance of the caterpillar is a bluff--it looks ferocious but is harmless. Unlike most caterpillars that spin cocoons, the hickory horned devil burrows into the ground to transform into an adult moth.

I was walking around in my yard, picking up broken twigs and came upon this thing! Yikes... I had to pick it up with a stick and put it in a container and get it to my grandson for his "Show and Tell". What a scary looking insect, or whatever.....

I've been trying to find out what this was all night. My sister and I came home from school and found it out by our mailbox while walking the dog. It does make sense now though, since we have an oak tree nearby. I thought it was some kind of endangered species of insect or something. Good to know it can't hurt me though.

I live in Colts Neck, NJ and found one of these caterpillars at the end of my driveway. It scared me to death. My husband scooped it up in a cup and showed my father in law, but they couldn't figure out what it was. looked to me like it should have come out of the rain forrest or something. My husband then let it go. Local farmer told us it was probably a tomato caterpillar, but when i looked that up it looked similar, but not quite the same. Luckily came across your site and recognized that this was it. Our yard is full of black walnut trees so that explains it. thanks so much to this site!

My son Eric, was helping his neighbor with a tree stump. Here was this huge caterpillar, the hickory horned devil! We were not aware it was in this area. It was huge and quite unique!! He has pictures if you wish to see it! Very exciting! Virginia Wolff, Joplin MO

A parent brought one of these into our school for the kids to see. I live in north central Florida. I want to keep him in class and let him turn into a moth. How would I go about doing this? Thanks, Vicky

On 9/18/09 I saw a horned devil walking across the walk way in our back yard. It was about 5" long and much bigger than any caterpillar I had seen. My wife came out with only a towel on when I said "come quick". We have an ash and walnut tree in the yard. It must have been looking for a place to burrow before changing. We live in Philadelphia.

We found a huge orange fuzzy moth while on vacation in Wildwood, NJ in July. It was sitting on our balcony, alive, but not moving much. how surprising to know the caterpillar is sooo big. Thank goodness we didn"t stumble across it in it's "devil" phase.

I found one of these just north of Houston, TX(in conroe). It was about 6 inches long.. Never seen anything like it... It is now in an aquarium... It shrunk to about half it's size and went under the dirt.... It's probably in it's cocoon now...

Found one of these last week (9-9-09) in central Ky, it was along a creekbank. it has since cacooned itself and we're awaiting it's opening.

I am a Locomotive Engineer and this afternoon, 9-15-09 we had one of these "fall" out of the sky and hit the front windshield on the locomotive. I'm guessing he fell out of a tree.When it hit, there was a large amount of goop that came out of him but he landed on the nose of the cab and we were able to stop and pick him up. Thought we discovered a new species for a minute :). Brought it home to show my son before it dies but it won't last long, it's covered in I guess what is blood and has a large bulge on the side now. Pretty crazy looking creature though.

We found one in South River, NJ 9/13/09 at our local baseball field. Freaked me out when I almost stepped on it in the grass. My 7 year old son brought it home to show his science teacher tomorrow. Very scary when you just happen upon it!!
Xavier Goines said:
We live in Johnson City, TN. We found one of these in our front yard today (9-12-09). I was wondering if anyone knows if you can keep one of these and watch it change into a moth? My mom is a science teacher and we would love to put soil in a fish tank and watch it do it's thing. Does any one know if this will work?

We found one of these yesterday, Sept 5, 2009 on a homeschool trip to Blue Jay Point in Raleigh, NC. It took a while to get the courage to pick it up, but no one knew what it was until the park ranger went and looked it up. Anyone know when they burrow? Ours was about 5 inches long.
