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.

We found this beauty today in our back yard here in Charleston SC. I've put him in a jar to show the grand kids. I've given him some small pecan branches to eat on. Is there a way to keep him for a few days?

looks like largest cluster of horns is on rear.

To my knowledge, the Hickory Horned Devil is benign. The spikes are mainly just a show to ward off predators. I don't think there is any poison. The one I handled in these photos was rather a gentle giant and over the years I've only read similar remarks about them.

Found one of these bad boys in High Point, NC today. He scared me, but I was beyonddd fascinated (being that I'm an amateur nature photographer). I have taken literally hundreds of pictures of him by this point. My parents and others thought I was mistaking him for a snake (really? -_-) till they saw with their own eyes. We put him in a terrarium till my mom researched and found out what he was and how he worked (burrowing). So we put him back in the yard and I've been watching him to mark the spot where he burrowed...but that's the problem. He's already in his third stage (having turned turquoise) and it's time for him to burrow but my yard is topped with mulch, under that has an anti-weed layer of thin black fabric and then some lovely red clay underneath that. I'm honestly worried that he won't be able to burrow here. Does anyone have any recommendations? Thanks.

Hi! My son and his friend saw one of these amazing, beautiful caterpillars yesterday.
They were so excited to see such a unique caterpillar. We looked it up right away and found out the name of the type of caterpillar.
Since then....my son has been researching and reading up on all the neat facts about the hickory horned caterpillar. The kids let him crawl back into the trees...but really want to see one again.
Where are they most likely to be found?
This one just wandered out of the garden...so we are hoping to see another.
Thank you!

Found one of these crossing my back yard when my Golden Retriever stopped to sniff at it. Glad to find your website and discover I saw my first hickory horned devil. I measured this one at 5 inches long. I live in a rural area close to Montgomery, Alabama and I have never seen one of these before. I placed it at the edge of a wooded area with a lot of mulch and downed limbs. I went back to look for it and saw it crawling along a limb into the woods. A friend thought it might be poisonous till I found your website and confirmed its identification. Thanks for your informative website.

Neighbors found one today in Haddonfield, NJ. All the kids stopped to look on the way home from school.

I was fishing the Wissahickon Creek in Philadelphia and I noticed this long turquoise object floating by me in the water. I took my rod and flicked it out of the water, and came to discover my first Hickory Horned Devil. I was amazed. I assume he had fallen out of a tree into the stream. I placed it on the stream bank and took plenty of photos and video. About 20 mins later i went back to look for him and it had burrowed into the ground under a dead tree, with just a bit of his body still exposed out of the hole. Ive been fishing this creek for 25 years and have never seen one, or heard about one before. Amazing creature.

I found this creative looking creature when the whole family whent camping. I was riding my bike when I almost ran it over. I thought it was only a humongus magnolia leaf with all sorts of weird bugs all over it, then I looked closer, but it snapped at me. I told every one but they didn't beleive me until I dragged my mom over there. Every one beleived me when they hurried over after hearing my mom scream bloody murder! After that, we took pictures and posted them on Facebook. My uncle was being an idiotic bozo and was messing with it and it was going crazy and trying to attack him. But I've always known that thay are harmless. That's my story of how I found a Hickory Horned Devil


Feb 8, 2012

My friend found this thing in her backyard about 6 months ago, everybody down there was totally scared of this creature. Later it simply went back to woods without harming anybody. She lives in New Stanton, Pennsylvania.

Wow! Found one crawling on the sidewalk today in Morganton, NC. Put in a jar to show the kids when they got home from school. It looks so intimidating! Was told that it was a tobacco worm but wanted to be sure. Thanks for your site!

I was riding my bike up the gravel drive and I came across this Scary thing! Could not beleive it. Went to get a jar, so I could show my grandparents, husband and kids! Grandpa thought it was a saddleback, but I looked it up on internet and found out different. WOW!! I later let him go into the woods. He is happy that I turned him loose, and maybe I will be lucky to see the 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.....

Aug 25, 2010

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!

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

Aug 28, 2010

you really cant inside i believe they have to go through the freeze period cause the burrow in the ground for their transformation in spring they need a branch to come straight out onto to hang upside down to dry and straighten their wings if this isnt available their wings will wrinkle up and not fuction properlybut good luck just the same hope you can figure out some way to do it and film it cause everyone wants to see myself included

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.

Sep 5, 2010

actually in the "devil" form it looks really interesting and when it is full grown it has even more horns.........my cousin came across one and i have been interested in it ever since

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.

Forgot to mention it was in Rockville, Maryland.

Are these things new to the area or just very rare?

Just saw one of these at a park in Shepherdstown,WV. I've never seen anything like it before. The kids thought it was pretty amazing.

Catherine Brown

Sep 15, 2009

Our's too emitted a red looking goop in the cup we put him in. The local ag. center said to put him in a container with soft soil and it would

burrow down in the soil. As soon as my husband

put him on top of soil it quickly burrowed down! We are hoping to have a Regal Moth later!

Catherine Brown

Sep 15, 2009

We found one on 9/14/2009 in Hamilton,NJ. It is very freaky and with two boys that love to catch bug and study them they WILL not even look at it long! We too

will be taking it to school! To freak out others - hee hee.

Where in Hamilton NJ did you see the Hickory Horned Devil?

Over by Hamilton Market Place! off RT 130

Is that where BJ's and Wal*Mart are at ?
I don't drive, so road names are a whole different language to me.

My sister works at the Wal*Mart and when she was getting out of the car to head into work she and her husband spotted the Regal Moth right in the parking lot on the ground right next to where they parked. It's length was about the whole width of one of the white lines in the parking lot.
She was nice enough to take a picture, but I really wanted the Moth.

If that's the same area where you saw the Hickory Horned Devil, I might have to consider moving to Hamilton just so I can have a better chance of finding The little devil.
I'm now going a 5th year without finding a healthy one sice I started collecting caterpillars.
This I had finally found one, It looked like it had hatched from its egg recently cause it was very tiny, but after 3 days it died.

You would think it would be easy to find one here in Plainsboro.

It's sad that the one in the picture above had a sad fate, the parasite eggs.

I had an Imperial moth caterpillar that had parasite eggs all over it and I spent 4 hours carefully breaking all of the eggs to give the poor caterpillar a better chance at surviving its full life cycle, but the caterpillar never went to his next stage and the wasp never hatched either.

sorry if I typed to much.

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

Sep 12, 2009

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?

Laura B

Nov 18, 2009

I'd suggest letting it go. If you're serious about keeping it then I'd read the following: http://ipm.ncsu.edu/current_ipm/96PestNews/News18/ornament.html.

SO, sounds like to me that you need the proper soil in the tank. Make certain it has the proper food source available (hickory, walnut, butternut, pecan, ash, lilac, persimmon, sycamore, etc.) if it is still growing. Also attach a screen to the tank. When the moth emerges after Winter it will only live a few days. They are fairly rare to see. Please let it go so it can mate with another royal moth. The royal moth doesn't have a mouth, and its sole purpose is to breed and lay eggs. Please help the population by releasing it. Keep in mind this process is very slow. Don't give up on the moth it will become. Good luck!

hey...we're from sulphur, la. next to lake charles. my dad found one just a couple of days ago when he discovered a big pile of what looked like rabbit droppings. not having seen a rabbit recently...he simply looked up and it was in a gum tree next to his shed. stretched out....it's over nine inches long. it's currently in my possession to find out what it was. we heard the same thing...that they were from the east coast. wonder what they're doin this far west.

Found one on our wood pile yestreday in NJ 9/6/09.Real "freaky" looking my son wouldn't even get close. So strange had some of the neighbors over to find out what it was never seen one before. I was told it was a horned tomato worm. Thanks for your site and info now I know what it really is called (HHD).

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.

Emma Goldberg

Sep 1, 2009

I almost cycled over one of these while on vacation in Washington DC, on Rocky Creek Trail. I took a photo, and an expert at the Insect House in the Zoo was able to ID it for me. I was fascinated by it, and have never seen such a big caterpillar before. While I was sketching it on a postcard, it occured to me that it is pretty similar (except for the horns) to the Very Hungry Caterpillar. Has anyone else noticed the startling resemblance?

Marni Harker

Sep 8, 2009

Me too! Just found one of these this afternoon in Rock Creek Park while going for a bike ride. Moved the big guy back to the grass & trees since he/she was about to get flattend by a car tire.... What a cool creature; truly the highlight of my day.

Me and my two boys where down by a stream that runs by my house in north carolina and we found a HHD floating in the water I thought it may be posiones so we put it in a fish net and brought it back to our house and asked our elderly neighbors if they have seen any thing like it before and they all said no! One neighbor said to take it to a museum thanks to your site i was able to find out what this thing was thank you!!

Found one in our front yard in Murphysboro Illinois last week. Freaked us out! 2nd time I had seen one in Murphysboro so they must live in Southern Illinois. We only have pine trees in the front though so I don't know what it was doing there.

Rhonda Mense

Aug 8, 2010

We just found one of these in our yard in St. Libory, IL. We are approx. 40 miles from Murphysboro. Scared the daylights out of me. It is one scary looking caterpillar. We have a 7 pecan trees in our yard and a walnut tree. I am glad I know what this is now and won't be so frightened the next time I see one.

My mom and son just found one these scary creatures outside by our creek. Braxton is 4 and wouldn't rest until I found out what it was called. It was huge. Every bit of 6 inches. My mom has trees, a creek, and squash field behind her house so we were not sure about it's habitat. Thanks for the pictures. The appearance is scary and will forever be burned in our brains.

I found one of these giant caterpillars September 19 2009 along the edge of the woods in Morrisville Pa (at the Graystone Woods). It was crawling along the ground amid a large stand of Virginia jumpseed nearby to walnut,oak, tulip poplar, beech and hickory trees. The dirt is very dry and loose there and I am guessing it was planning to burrow and go into it's pupae stage (from what I have read so far). It was quite a thrill to see such a thing; my first ever!

I was walking to my parents today and found a hicory horned devil, this was the first one this year. I found 2 last year and this is the only 3 we have ever seen in the past 45 years my parents have lived there. We live in western Pennsylvania and they are not native to this area. We have never seen the moth they become but wish I could. I took it to our local newspaper and they took about 18 pictures of it and are putting it in the newspaper with an article. It is definately amazing looking. I can't explain why I have found 3 of them in this climate. Thanks

I happened across one of these this afternoon in my backyard under the walnut tree. It was such an odd color & shape, I thought it was a broken piece from a plastic toy. Then it moved! I moved the little devil (haha) to a safe place and have been searching for info. I'm glad to have found your web site.

Spied one of these creatures in the middle of the road in Westminster, Md. My 6 yr old son says we're being invaded by aliens from Mars. My 8 yr old daughter says it doesn't need to dress up for Halloween. All I can say is, unbelievable!

My son's day care class found this in the back yard. We live in KY. I've never been a fan of creatures with more than 4 legs, but I must admit I was amazed at this critter! Yesterday, the class let "Herbie" go so he could burrow into the ground. It was sorta cute in a bazzar way!

aaarrgghhh - we found one in our yard at work today. Somebody put it in a box and brought it in to show the office staff. I felt sure it had come in on a shipment from the far east or somewhere. It scared the bejeebers out of me. Glad to know that it was harmless and native to the US.

Fascinating but weird!

i found one of these about 2 years ago near my dog, it was hanging upside down from a branch and my dog kept barking at it, so i went out to see what it was, and it fell right in my hand! at first i thought it was deadly, due to the color scheme, but it was harmless!

Hi, We found this amazing creature today in our front yard, everyone we question was sure it was a new species of some kind. So the kids and their friends took it to the local vet and they found out exactly what it was, the funny thing is they actually had already named it horn devil, they came pretty close.

My friend and I were driving down Old River Road in Duncan Falls Ohio, when I seen the big huge bug going across on the other side of the road. I turned around and picked it up for my daughters show and tell at school. We did a big green caterpillar search online to find out what it was, and to our surprise is was a Hickory Horned Devil. What an awesome experience it has been for our family, and for the class of second graders that will view this awesome creation of Gods handy work. I will return it to the woods where I found it, after show and tell.

We Were walking the dogs at the dog park when we found this huge blue caterpillar. I was scared of it at first but my mom said just watch it and don't touch it because it had large spines that could be stingers. We watched it for a long time as it made its way accross the park. We could not wait to get home and try to find out what kind of moth or what kind of caterpillar it was. It was the Hicory Horned Devil we found out.

8/3/07 I live in Coinjock, North Carolina. While in the next town over getting gas my daughter spotted a Regal Moth. We had never seen one before and did not know what it was. My daughter, who is an advid photographer, pulled out her camera and took a picture. I was able to learn about the Hickory Horned Devil and that it turns into a Regal Moth. A special experience for me and my daughter.

Hello. I'm a computer animator working on a new animated short film about the Hickory Horned Devil/Regal Moth. In researching them I came across your website and found your great photographs. I'm wondering if you could send me the full resolution photographs you've take so I can use them to help texture my 3D model?

Hope you can help me out. Fill free to email me anytime.

Last weekend, Sept 17 06, we were at Rock Bridge Trout Ranch in Southern MO. Wewere leaving and a Hickort Horned Devel fell from a sycamore tree and landed with a thud on the windsheild of out truck. I ahd never seen or heard of this creature. We stopped and showed it to the guys behind us as we were all facinated at this "thing". My husband rescued it and put it on a near by tree. Thanks for the photos and the information...I will pass it on.

We found our first hickory horned devil today on a lovely stroll around the campus of New Bolton Center of U Penn vet school in Kennett Square, PA. We were delighted to encounter such a spectular beast!!!! We were tempted to pick it up and keep it for a while, however we were frightened by its horns!!!!

We found one of the Hickory Horned Devils while camping in Ohio. We have never seen one before. We took it to the camp office and they told us it was either a lunar moth or a mammoth moth. Thanks to your website we now know what it was. I guess we need to go back and let them know what it was. Thanks again

My children found one of these while hiking in Western PA on 9/10/06. I've never seen anything like this!! Amazing! My daughter kept it alive in a box with grass and twigs and took it to school to show the class. She then released it back where she found it. Thanks for the great info.

I live in Chesapeake Va. and found a Hickory Horn Devil crawling across my mother-inlaws drive way and caught it to give to my nephew who loves things like this. Very interesting info on this. I did not know what it was either. We have let it go so it can become a beautiful Moth. Thank you so much for the info.

hi,I am on your site to learn about the Regal Moth.I live in Hockessin Delaware and I came out to put out my recycling this morning 7/19/06 and noticed this huge and spectacular Moth on one of my columns and it was a Regal Moth.I donated it to The Ashland Nature Center and she laid eggs and they will be picking up tommorrow. I have had a nice experience. My name as you know is Vanessa also genus of Butterflies. Red Admiral, cosmopolitan Lady and the American Painted lady. Maybe the Moth knew it would be safe. Thanks for letting me share with you.

My neighbor Elsie found one of these walking accross her front walk. None of us had ever seen one before. Had to look it up online to find out. Would loved to have seen it caccoon but since it buries its self I guess we can only hope the moth comes to visit too next summer.

I live in Pennsylvania, and was with my two boys in a creek area of glennside Pa.and found this very colorful caterpiller and was very confused. Came home and went on line to find out what it was, its looks are very risky looking. The name fits the bug.
