Harris's Three Spot Caterpillar
(09/04/2007) Help!
I failed to mention earlier that we're in Greensboro, NC and the little guys are over 2 inches long. This caterpillar, yes, that is a caterpillar, is eating my fringe tree which is very small and can't take much more! there are five of these and I don't want to kill them if they are going to turn into some lovely butterfly or moth.... it's head is to the right, with the three hairy brown balls hanging off of it....lower left is its back end.
Melissa



Hi Melissa,
Probably 15 letters will go unanswered because we spent so much time trying to identify your bizarre caterpillar. We were relatively sure it was an Owlet Moth in the family Noctuidae, one of the largest moth families. We scoured BugGuide until we located Harris's Three Spot, Harrisimemna trisignata. The hairy balls are actually "old dry head capsules shed by the earlier instars!" The adults are a very lovely moth, also pictured on BugGuide.

Cecrops Eyed Silkmoth Caterpillar
(09/04/2007) Stinging Rose I believe
Hello!
My name is David Donaldson, I am a nature photographer and  recently I was backpacking through the woods of the near Flagstaff, AZ when I came across this little thing on the ground. Could you possibly let me know if my assumption on it being a version of the stinging rose. Thanks for your time!
Dave Donaldson



Hi Dave,
We have gotten four requests for identifications of similar caterpillars from Arizona in the past week. They were all members of the genus Automeris, but there are at least four species found in Arizona. Your caterpillar is the only one we can identify for certain. This is a Cecrops Eyed Silkmoth Caterpillar, Automeris cecrops. It matches an image on the Butterflies and Moths of North America website.

NOT Luna Moth Caterpillar but Polyphemus Moth Caterpillar
(09/03/2007) Luna moth larva this far north?
Hello Bugman...
You have a wonderful site here and I'm hoping you can help with identifying a bug for me. It is about 2 1/2 inches long and as thick as well... my thumb comes to mind but a tube of lipstick is about right. I discovered a very large caterpillar marching across my front lawn this afternoon. (September 3 2007) I took about 25 pictures of it and came to the conclusion it is a luna moth larva....BUT I cannot find anywhere that they live this far north. I live in central British Columbia, Canada. Prince George, to be precise. I found that they eat paper birch so I deposited it there. Now don't get me wrong, I love my paper birch but it looked like it needed a tree and had it succeeded in getting over to the neighbors it probably wouldn't have made it to the end of its already, too short, natural life. Long story short.... it seems to be spinning a cocoon. I'd like to see the results and take a bunch of pictures. How can I do that without buying the bird cage? Also, will this larva live inside the cocoon all winter? Even if it's -25 or -35 celsius and has a mountain of snow heaped on it for 5 months? Maybe I will buy the cage.... I have bird feeders out but that's no guarantee they won't eat the big green bug. I'll attach a couple of pictures (I resized them to 1/3rd their original size) and maybe you'll be able to identify it as something other than a Luna. (I really hope it is a Luna and that I'll get to see the final results next spring) Thanks in advance for your expertise. Sincerely;
Heather



Hi Heather,
This is a Luna Moth Caterpillar and they do live in the extreme North. They spin a cocoon around a dried leaf and pupage inside. The leaf remains on the ground among leaf litter. The blanket of snow actually helps keep the pupa from freezins as it acts as insulation with the decaying leaves providing additional heat.


Correction(09/04/2007) "luna" from BC, damsel drowning
A couple of questions regarding recent postings:   Are you certain the Luna Moth caterpillar from British Columbia is in fact a Luna?  I've raised Polyphemus for a number of years, and it sure looks like a "Poly" to me.  The white bars on the sides are key.   As for the damselfly drowning during mating, it seems to me I've read the males sometimes do this to prevent other males from mating with "their" females.  Anything to that?   Cheers!

Hickory Horned Devil: Third Instar
(09/03/2007) Hickory Horned Devil Variation?
Greetings,
I found this little beauty while walking around our farm on a photography stroll.  The reddish/plum color caterpillar was on a sweetgum.  I've looked around the .net and found no specimens that looked like this one....excpet for the Hickory Horned Devil.  Could not find one unless it was green in color, but the markings and the horns were almost identical on some of the photographs I saw.  Photo taken on September 3, 2007
Jose



Hi Jose,
This is a Hickory Horned Devil in its third instar. Caterpillars go through five instars as they grow, each time shedding their skin and changing appearance. In some species the change is quite dramatic. In two more molts, your specimen will be much larger and have the characteristic blue green coloration with red horns of the fifth instar, fully grown Hickory Horned Devil. BugGuide has a nice series of images from egg to final instar.

Parasitized Cecropia Caterpillar
(09/02/2007) Large green caterpillar
Hi,
I just found this large catterpillar hanging from a tree and was wondering what it was. I found it hanging in what I think was a eurpean buckthorn tree in the Oak Ridge's Morraine, Clarington, Ontario, Canada. It was at the edge of a forest with bitternut hickory trees, swamp oak, white oak, red oak, pines, maple, silver birch, butternut, hawthorn, yellow beech and a wide variety of plants. I'm curious about what it is and will turn into! It seems to be quite close to changing into a chrysalis, it was hanging upside down and not moving when I found it. It's very inactive.
Stella



Hi Stella,
The good news is we can identify your Cecropia Moth Caterpillar. The bad news is that it will not live to adulthood. The orange, yellow and blue tubercles are typical caterpillar markings, but the white nodules with the brown spots are a sign the caterpillar has been parasitized, probably by a Brachonid Wasp. These pupa look much smaller than the Brachonid Pupa we sometimes see on Sphingidae caterpillars and Saddleback Caterpillars, so they must be a different species. We will try to contact Bill Oehlke to see if he can tell us what species of Brachonid parasitizes Cecropia Caterpillars.

Correction: Pine Devil
(09/01/2007) can you identify ?
About 3 inches found in my backyard. Reddish brown thick. Six horns in front and one at end.Thank you P.S I looked everywhere online and couldn't find it. We live in North Carolina



We are guessing that this Hickory Horned Devil is brown instead of the usual blue-green color because it is ready for pupation.

Correction (09/02/2007) Misidentification
Hey there,
I was cruising your site and noticed that you had misidentified a prepupal caterpillar posted on 9/1/07. You identified it as  C.regalis that was brown because it was ready to pupate. C. regalis turn an aqua color when prepupal, but there is another Citheronia species in the area, C. sepulcralis . This the prepupal larva of the Pine Devil Moth. Its coloration and markings, or lack thereof, are right and the species becomes increasingly more common towards the south-east where they can have 2 or more broods per year. I hope that this info helps anyone else that might come across a Pine Devil on one of their pine trees or in search of a suitable pupation site that might consider it a Hickory Horned Devil. Cheers,
Josh

Imperial Moth Caterpillar
(09/01/2007) Imperial Moth Caterpillar
Hello, Bugman,
We were called to retrieve this charming fellow from someone's yard.  I had never seen an imperial moth caterpillar in real life before (I believe we're at the very edge of the range), and was shocked at how enormous it was.  My mother isn't a fan of bugs, and refers to the critter as "the crawling turd," and is fascinated by its "Predator-like butt. I've placed the caterpillar in a container (12x6x12") with a bunch of loose dirt.  At the moment, it's just wandering around, but I'm hoping it will burrow down and pupate soon.  I guess I'll have to wait a few months to get picture of the adult, barring infestation by tachinid maggots. Regards!
Emily



Hi Emily,
Thank you for sending your photo of the Imperial Moth Caterpillar acompanied by you mother's colorful description.

Saddleback Caterpillar
(08/31/2007) caterpillar that stings
I found this bug on my blueberry bushes and it stung me.  I thought it was stinging nettles but on closer look found this bug. What's that bug?
Nancy



Hi Nancy,
This is a Saddleback Caterpillar and yes, it does sting.

Unknown Caterpillar: Automeris species
(08/30/2007) Hi
I hope you can help me...I found this caterpillar on my back porch in Prescott AZ. I am about a mile in altitude in the "high desert west". I think it fell from some trees with that green material in the picture. I can't figure out what it is. I am guessing it would sting me. Thank You,
Craig



Hi Craig,
This is some species of caterpillar in the genus Automeris. These are giant silkmoths. There are several possible species in Arizona, but none seem to match exactly. They include Randa's eyed silkmoth or Automeris randa, and Cecrops eyed silkmoth or Automeris cecrops. A nearly identical image is posted to BugGuide with the possible identification being Automeris boudinotiana. Moths in the genus Automeris are known as the Eyed Silkmoths and some species have very localized populations. Automeris caterpillars do have stinging spines.

Giant Swallowtail Metamorphosis
(08/30/2007) Giant Swallowtail (Papilio cresphontes) developmental series
Hi Lisa Anne and Daniel,
Glad to see that you are keeping up your great work with your website. Last year I submitted some picture series about the development of butterflies. This year I would like to share my Giant Swallowtail shots with you.



I found 6 caterpillars on Prickley Ash during the summer in Wisconsin, and breeding this species is a wonderful experience. My girlfriend Megan will be delighted to see "her" caterpillar on your page, which she got as a present from me to encourage her slightly increasing interested in bugs. Keep up the great job! Best wishes from Madison/Wisconsin,
Thomas Werner



Hi Thomas,
Thanks for sending us your wonderful Giant Swallowtail metamorphosis images.



Sycamore Moth Caterpillar
(08/29/2007) Peculiar Hairy Orange Caterpillar Found in Belgium
Hello dear bugsir,
Recently, my parents witnessed a peculiar orange caterpillar falling from out of the tree in our garden, right here in Kapellen, province of Antwerp, in Belgium, and they took some pictures of it. I would like to apologize for the bad, blurry, unclear quality of 3 of those pictures, since my parents aren't professional photographers (they aren't even amateurs ...). The only clear one is the last one (and it almost can be used as a decent wallpaper!). I was very intrigued when i looked at those pictures, because here in Belgium, our insects dont look that colourful, or exotic. It does seem very out of place here. I've tried searching some sites (i even looked at all of the caterpillar pictures on your site) but no info came up about this species. I really want to know what type of caterpillar it is, and if those hairs are venomous or not, because i have a little phobia of caterpillars. So if i walk under under tree and this beast falls in my neck, i really want to know its name and what effect those hairs give, before i start to run off and scream like a girl. Regards,
Bart from Belgium



Hi Bart from Belgium,
We did identify this species of Punk Rock Caterpillar in August 2006. It is on our caterpillar 6 page. It is a Sycamore Moth Caterpillar, Acronicta aceris. Sadly, the link to the UK website where we originally identified it is no longer active.

Buckeye Caterpillar
(08/29/2007) found another caterpillar
We are having a ball finding caterpillars in the flower garden and watching them transform.  It's been a great educational experience for all of us and my four year old is very fascinated at the entire process.  She name them all "Leah".  Anyway, I again searched all 10 caterpillar pages and was unable to locate our newest find.  Could you please help.  Thanks
Mitzi



Hi Mitzi,
This catepillar is one of the Nymphalidae or Brush Footed Butterflies. We are nearly positive it is the Common Buckeye, Junonia coenia. According to BugGuide, the caterpillar host plants include: "Plants from the snapdragon family including snapdragon ( Antirrhinum ), toadflax ( Linaria ), and Gerardia ; the plantain family including plantains ( Plantago ); and the acanthus family including ruellia ( Ruellia nodiflora ). "

Gulf Fritillary Caterpillar
(08/28/2007) Gulf Fritallary?
Hooray!
I’m excited to have made my first bug discovery which I believe is a Gulf Fritallary. Saw the other postings on this caterpillar, but I’d love to find out some more about it to share with my kids (they were just as excited to discover it).
Armando, Los Angeles.



Hi Armando,
Once you have a name, it is remarkably easy to locate information on the internet. This Gulf Fritillary Caterpillar, Agraulis vanillae, feeds on passionflower vine and will metamorphose into a lovely orange butterfly with silver spots on the underwings.

Hickory Horned Devil: What's That Bug? "is much better than playing Playstation"!!!
(08/28/2007) Huge, Crazy Looking Caterpillar
Hi there,
Perhaps you can help. My son and I found this on Sunday, August 26, at a park in Irwin, Pennsyvlania. We almost stepped on this thing. We look for bugs all the time and have never seen anything like this. We did not keep it nor touch it. Do you know what it is? Sincerely,
Amy Vandermer and Mason (age 7)



Hickory Horned Devil

Ed. Note: Since we don't have the time to post every submission that is sent our way, we sometimes just make a quick reply (see above). In this case, posting two additional images of Hickory Horned Devils in the past 24 hours prompted our decision not to post this letter. Then we got the following response, which is so endearing, that we rescued the original letter and photograph from the trash.


Thanks so much! Your Site is Awesome!
Thanks so much.  We actually spent the rest of the evening on your website and found what the answer was.  My son was so excited about your site after baseball all he wanted to do was look at bugs and drawn his own pictures. You might be happy to know that a 7 year old, second grader actually said . . . . . . "this is so much better than playing Playstation!" . . . his last words before bed were "after school tomorrow I'm coming straight home to identify more bugs!" You guys are awesome!

Tersa Sphinx Caterpillar
(08/28/2007) crazy!
While taking care of my flowers in my landscaping, I spotted a creature about 1 inch from my hand-scared me to death because I thought it was a snake.  I realized it was only about 3-4 inches long.  It also has this thorn thing sticking out of the lower end of its body.  The next day, I saw another weird creature in my landscaping and grabbed my camera.  I did not think that it was the same type of creature because the first had a head just like a snake but this creature has a long snout.  After watching it and taking several pictures, I pushed it along with a wire piece and it decreased in size and then looked just like the creature I thought was a snake.  What is this thing???   OK, I found it....I feel very silly, but the first one I saw was brown.  I am sending my pictures anyways......
Monica Lain



Hi Monica,
Many caterpillars, your Tersa Sphinx Caterpillar included, have markings that resemble eyes. This is a protection against birds and other predators who might be startled by a "snake".

Smeared Dagger Moth Caterpillar
(08/27/2007) Smeared Dagger Moth Caterpillar
Fellow bug fans,
My kids and I have used your site to identify dozens of insects over the past few years.  Your site is always the first place we go when our paper guidebooks fail us.  Once again you've come through for us in identifying what we believe to be a Smeared Dagger Moth caterpillar (Acronicta Oblinita).  We found this one feeding on marsh grass along the shore of Jug Bay on the Patuxent River in Maryland.  You have a couple pictures of them, but we thought you might like another.  Thanks for a wonderful website!
Ned



Hi Ned,
We love hearing from people who have the patience to plow through our archives and successfully identify their unknown invertebrate discoveries. Your identification of the Smeared Dagger Moth, Acronicta oblinita, is on the money.

Hickory Horned Devil
(08/27/2007) what is this?
Hey Bugman! My daughter and I saw this bug/worm (pic enclosed). Thought it may be a tomato bug but much larger than I've ever seen and what about the horns? Hope you can help. Thanks,
Brent Connors



Hi Brent,
The fierce looking but harmless Hickory Horned Devil is generally regarded as North America's largest caterpillar. It has probably come down from the trees where it has been feeding so it can burrow into the ground to pupate, the next step in its metamorphosis into the lovely Royal Walnut Moth. We have had readers say the Hickory Horned Devil resembles a Chinese Dragon.

Hickory Horned Devil
(08/26/2007) Can you help?
Hi. Please see attached photo. We found it in our woods and we have never seen anything like it.  We were wondering if you could identify him and let us know what he will become. Its almost as big as my husband's hand! Not sure what tree it was on. We have a lot of sweetgum and poplar. Thanks so much for your help.
Jennifer Poggemann
Southeastern Indiana



Hi Jennifer,
This is a Hickory Horned Devil Caterpillar. Several weeks ago we commented that we expected to see more requests for their identification this year because of the large numbers of adult moth images, the Royal Walnut Moth.

Spiny Oak Slug Caterpillar
(08/25/2007) slug?
My daughter found this creature crawling on a rotting stick in the woods in Southwest Missouri.  We initially thought it was a caterpillar, but see that it moves like a slug or snail.  It also appears to have antennae at the front like a slug, but similar protrusions all along its body.  Are the white things on its back eggs, or perhaps parasites?  It is approximately 3/4 inch long.



This is one of the Slug Caterpillars in the family Limacodidae. We believe it is a Spiny Oak Slug, Euclea delphinii. The "eggs" are really Brachonid Pupa, a parasite that feeds on the caterpillar's inner tissues.

Unicorn Caterpillars
(08/25/2007) Found on a rose leaf
I found several of these caterpillars on my rose bush and I can not find any info on it. can you help?

Hi Ann,
These are a type of Prominent Moth Caterpillar known as the Unicorn Caterpillar, Schizura unicornis. BugGuide lists many food plants, including apple (related to rose), willow, alder, hickory, aspen, birch and elm.

White Lined Sphinx Caterpillar Invasion
(08/25/2007) caterpillar
Hi, I'm Kayla from Flagstaff, Arizona. This morning my mom discovered these caterpillars, and we're rather disturbed by them because we've picked up at least 560 of them, and still have more. I was wondering what kind of caterpillars these are, and how we could have gotten so many in a very short time. What should we do with all of them? Thanks.
Kayla



Hi Kayla,
These are White Lined Sphinx Caterpillars, Hyles lineata. Yours is the third letter in a week from Arizona that mentions huge numbers of these caterpillars. This is a common desert species and every few years there is a population explosion. These are edible caterpillars, but should you choose not to eat them, they will provide a sumptuous feast for birds and other insectivores.

Variegated Fritillary Caterpillar
(08/24/2007) is this a buckeye caterpillar?

Hi Carmen,
This is an exact match to a Variegated Fritillary Caterpillar posted on BugGuide.

Great Ash Sphinx Caterpillar
(08/23/2007) Leaning toward carnage.....
Dear What's that Bug?
First let me say I adore your site, I have used it to identify many a creature in and around my home and there are more than a few spiders that own there lives to you and your unnecessary carnage pages. Talk about guilt bombs, more about that later. I purchase a lilac bush for my husband this year, he mentioned that they had a bush near his home when he was a kid and he loves the sent of the flowers.  Earlier this month these worms or caterpillars showed up on the stems of that bush eating the leaves. When I first noticed them they were about an inch and a half in length and doing minimal damage. Now they are almost 4" long and are destroying the little bush. I have been trying for days to identify them and find out if I can move them to an alternate food source. As I mentioned they are almost 4" long without the horn. They have a voracious appetite and  appeared on a Lilac bush in Mid August in Lake Lure, NC,. They most resemble a Sphinx Moth caterpillar to me, They have seven pairs of oblique blue gray stripes, but,  lack the white nodules all over the thorax, they do have light green to yellow spikes on the top of the head? But not the underside. The horn is light green, not dark green or red. I don't think it is a Tobacco or Tomato horn worm larva but then I have seen a number of what seemed to be Tobacco or Tomato Horn worms that were ID'ed as Sphinx Moth Caterpillars and vice versa so I am a little confused. I have attached some pictures. The first is just something I found interesting. I had taken some pictures in the morning of the 20th and by mid afternoon the greenies were significantly reduced in size. You can see the difference in the first and second picture. I believe it was because it we were having record high temperatures and have had little rain, I think they just lost a lot of fluid. I am considering a quick and painless execution if they do anymore damage. The execution is scheduled for Sunset on the evening of August the 24th, they seem to do the most damage during the night and I don't think the Lilac can take anymore than that. I know you are busy and that you may not be able to get back to me in time to save either, but thank you for your time just the same.
Dani Whipple



Hi Dani,
First we want to say that the damage done by caterpillars to deciduous trees is not permanent as new leaves will grow back. This is some type of Sphinx Moth Caterpillar, and we are relatively certain it is the Great Ash Sphinx, Sphinx chersis. Larval host plants include " ash, lilac, privet, cherry, and quaking aspen" according to Bill Oehlke. We hope we have convinced you to stay the execution.


Update: (08/24/2007) Carnage averted!
The execution has been called off. I woke up this morning and the caterpillars eating the lilac bush were gone! The plant is in a pot on the deck so I don't know where they went, it does not appear that they burrowed. It's as if they sensed my evil plan ( like I would have killed them) and scattered. There is very little of the lilac left, I hope it recovers. I would still like to know what they were for certain.. Thanks again.
Dani Whipple

Hickory Horned Devil: Early instars
(08/22/2007) Hickory Horned Devil
Hey,
I've found your site to be a wealth of knowlege and information, which is a nice resource since i want to be an entomologist.  Anyway, a friend of mine found an adult regalis at a light in mid-July in Maryland which laid eggs.  I asked for a couple larvae when they hatched and she gave me 8 healthy 1st instar caterpillars on sweetgum.  They of course grew, but i lost 4 while they were shedding into the next instar. Is this common with regalis?  So i have four left, 1 third instar, 2 third about to shed into fourth, and 1 fourth instar.  I also switched them from sweetgum to norway maple when they became third instars for convenience reasons.  They LOVE it.  I thought that you would like some pics of the larvae.  I was also fortunate enough to land a female luna on August 10th.  I have about 100 beautiful first instar larvae which i have feeding on my poor sweetgum sapling.  I'll send some pics of them when they get big enough.
Josh



Hi Josh,
Sorry that we cannot provide mortality rate information on Hickory Horned Devils. Thank you so much for providing images of early instar caterpillars for our site.

Lobster Moth Caterpillar from Japan
(08/21/2007) Lobstermoth caterpillar pictures!
My house has a guest!  Well, this one is living outside.  When I found him (or her) clinging to my son's shoelace, I put him in a box and took him to the Butterfly House.  The lady at admitting, after peeling herself nervously off the wall, pointed me to the next building over where they concentrate on such lovely natural wildlife. Of course, I already knew I was holding a Lobstermoth Caterpillar.  What I didn't know was what this fellow ate, and what it's known as here in Northern Japan.  They're called Shachihokoga.  Ga meaning moth, and Shachihoko being those fish-shaped gargoyles adorning the roofs of some houses.  ... The pictures were snapped by a nice fellow at the nature center who has a camera that can macro.  Someday I'll have one.  Or learn to use one... or both.  He told me they eat chestnut, acorn and other such leaves.  Really?
Jill Sylvan



Hi Jill,
The crazy looking Lobster Moth Caterpillar, can be found throughout Europe, and in parts of temperate Asia including Korea and China as well as Japan. The range information was located on what we believe to be a Scandinavian website.



White Lined Sphinx Caterpillar
(08/20/2007) What is this?
Hi there,
I'm attaching a photo of what I would think is a hornworm, but I haven't found any photos anywhere of this caterpillar.  They showed up 3 days ago, overnight, and they are everywhere!  In the garden, the driveway, the lawn, backyard... they are even climbing the stucco walls of my home.  Help!  I've been scooping them into 5 gallon buckets...  what else can I do?  I live in Sedona, Az.   Thanks,
Norma



Hi Norma,
There are at least three distinct color variations of the White Lined Sphinx Caterpillar, Hyles lineata, and this is one of them.

American Dagger Moth Caterpillar
(08/20/2007) Hi I found this catipillar on my porch. Can you tell me what it is and what to feed it? from,

Hi Hank,
According to BugGuide, the American Dagger Moth Caterpillar, Acronicta americana, feeds " on leaves of alder, ash, birch, elm, hickory, maple, oak, poplar, walnut, willow and other deciduous trees "

Oleander Caterpillar: Do Not Eat Them until there is a detailed study of toxicity
(08/19/2007) they are everywhere!
Hi! We just moved into this house and we have these orange catepillars, with black tufts of hair crawling everywhere on our house.  We have searched and cannot figure out what type they are, what they eat, etc...  Their cocoons are black and thin because you can see straight through them.  We believe that they turn into a black moth with white spots, with an orange butt. Are these poisonous? Please what can you tell us about them.  They already had one set of caterpillars that cocooned and now we have a second set. Thank you,
Shereen



Hi Shereen,
This is an Oleander Caterpillar, Syntomeida epilais, which, as you know, matures into the Polka Dot Wasp Moth. They are probably feeding on your oleander plants, a flowering shrub that might be more likely to harm your children than these caterpillars are. Oleander contains Neriin, Oleondroside and Oleandrin and ingestion of leaves or stems of oleander can be deadly. Reportedly, even a single leaf might cause death. While oleander is a deadly poison for mammals, the Oleander Caterpillars are not affected. Quite possibly they store the poisons in their bodies and this might protect them. We do not recommend eating the caterpillars nor the adult moths.

Spotted Apatelodes Caterpillar
(08/19/2007) mystery caterpillar
I spotted this caterpillar on the underside of a leaf in the woods in central Kentucky.  It was about three inches long.  You can see some stripes under all the "fur" if you look closely.  If you can help me identify it, I would really appreciate it.  I teach biology at George Rogers Clark High School in Winchester, KY. Thanks,
Catherine Underwood
Lexington, KY



Hi Catherine,
We are suckers when a querent pulls the teacher card on us. Your caterpillar superficially resembles the American Dagger Moth, Acronicta americana, which can be viewed on BugGuide. The true identity of your caterpillar is the larva of the Spotted Apatelodes, Apatelodes torrefacta, which can also be viewed on BugGuide.

First Devil of the Season: Hickory Horned Devil

Brachonid Parasitized Tobacco Hornworm
(08/18/2007) what kind of caterpiller is this ???????
i found this catapiller on a bell pepper plant in my yard in jacksonville NC..was wondering what are the white  things on it and what type is it and does it turn into a butterfly??
julie -  jacksonville nc



Hi Julie,
Your Tobacco Hornworm Caterpillar, Manduca sexta, has been parasitized by a Brachonid Wasp that laid her eggs inside the caterpillar. The larval wasps fed on non-vital tissues and have now formed pupae of the surface of the caterpillar. The pupae will hatch into adult wasps and the caterpillar will die, never maturing into an adult Hawkmoth, the Carolina Sphinx. According to BugGuide: "Larva: large green body; dorsal "horn" (usually curved and orange, pink or red) on terminal abdominal segment; up to seven oblique whitish lateral lines, edged with black on upper borders. The similar Tomato Hornworm, Maduca quinquemaculata, has eight v-shaped stripes and a straight blue-black horn. These caterpillars are often confused and misidentified." Growing up, we referred to this as a Tomato Hornworm or Tomato Bug. We have received numerous images of Brachonid parasitized caterpillars recently, and are posting your letter and image as an excellent example.

Monarch Project: Caterpillar, Crysalids, and Butterfly
(08/18/2007) Monarch Project
Dear Bugman,
I thought I'd share with you this photo of my 6-year-old grandson's butterfly project.  The monarch emerged this morning from the first of 46 chrysalises (with more to come).  Thanks for your great website!
Nancy Codere
Cumberland, ME



Hi Nancy,
We only wish your letter had included a more detailed description of what the Monarch Project is. We are guessing your grandson collected Monarch Caterpillars off of milkweed plants and kept them in a cage to observe the metamorphosis.


Dear Daniel,
I thought I'd share with you this photo of my 6-year-old grandson's butterfly project.  He collects the caterpillars from a stand of milkweed in back of our house and keeps them in a 10-gal. terrarium with screen cover.  Everyday 3 to 4 fresh milkweed stalks are added as food.  When the caterpillars are ready, most crawl to the cover to begin their metamorphosis (an occasional one will hang from a milkweed stalk and make his transformation there).  When a chrysalis turns black (it's actually clear but the unborn butterfly's coloring shows through), we suspend the screen cover from a hook on the ceiling to observe the critter's emergence.  The monarch in this picture emerged this morning from the first of 46 chrysalises (with more to come).  Thanks for your great website!

Mantis eats American Dagger Moth Caterpillar
(08/16/2007) EATING Preying Mantis PIC AWESOME
Dear Bugman,
Our garden is always chock full of Preying Mantis'. It took me three years, but I finally saw one eating something! Looks like he caught some sort of caterpillar and was sucking out the inners while holding him in his grasp. Quite an awesome show, I must say!

Hi Rich,
We have been meaning to post your wonderful image for several days, but we are constantly barraged by new emails and you got lost in the shuffle. We believe this is a Chinese Mantid, Tenodera aridifolia, but would welcome an expert opinion regarding the identification. The caterpillar is an American Dagger Moth Caterpillar.

NOT Imperial Moth Eggs Hatch
(08/14/2007)
Well its only been about 4 hours since I took a photo of them and sent it. But checking on them at lunch time gave us a surprise, they were hatching. So I grabbed 4 or 5 different types of tree leaves to put in the cage. Do they need water?? or is the leaves enough. I really want the little guys to have a chance or turning into those beautiful Imperial moths.
Karen Maier
PS let me know if u want any more photos as they grow or if you have enough of that type. dont want to send any you cant use.



Hi Karen,
These are not Imperial Moth caterpillars. We fear you misidentified your original moth. BugGuide has an image of a newly hatched Imperial Moth, and it does not look at all like your caterpillars. We cannot identify your specimen from this hatchling image. We suspect this is still one of the Giant Silk Moths. If you describe the moth, we may be able to identify it. It would be great if you could take a photo at each stage of development, known as instars. Each time a caterpillar molts, there is a new instar. There are five instars before pupation. You caterpillars will fulfull their water needs through the leaves they eat. Thank you for noting in your photo title that the eggs hatched after four days.


Sad Update
(08/16/2007)
Im sorry to say that all of our babies died. Im not sure why, I gave them the leaves from the tree they came from and a few others too. but they just sat around and didnt seem interested in them. and by today they were all gone. I wish we could of found out just what kind they were.

Saddleback Caterpillars
(08/13/2007)
Dear bugman,
We found four of these bugs in Southern New Jersey on August 13 on a Burning Bush (it was not actually on fire, thats the name of the bush)! Whats that bug? Please reply if it is not too much trouble!
Josh Gager & Lindsey Williams



Hi Josh and Lindsey
These are Saddleback Caterpillars, Sibine stimulea. Handle with care since those are stinging spines that will cause local irritation, but no lasting effects.

Monarch Caterpillar Metamorphosis and Tachinid Fly Parasites
(08/12/2007) Monarch Bodysnatchers
Hello, Bugman,
I recently placed 2 large monarch caterpillars in an terrarium with some milkweed, so I could watch them go through metamorphosis.  All was well... at first.  One morning, I found one of the caterpillars hanging from under a branch, as though ready to pupate, but it was dead, shriveled, and and clear strands hanging from it.  There were two small, yellow maggots in the tank, as well as a red pupa.  After a bit of searching, I found this site http://www.monarchlab.umn.edu /research/PNE/creasey.aspx .  Apparently, an introduced tachinid fly, Lespesia archippivora, was brought over to control cutworms, but attacks non-target species like monarchs as well.  Fortunately, the other caterpillar seems to have dodged the bullet, and has formed a lovely chrysalis. Regards,
Emily

Hi Emily,
Thank you for your wonderful letter, excellent photos, precise documentation, and technical research. Though we approve of biological control methods over pesticides, we always question the introduction of biological agents before the total ramifications of the actions are made apparent.

Leafy Spurge Hawkmoth Caterpillar
(08/11/2007) hornworm
Can you help me identify this beautiful hornworm ( I think)?  There were 3 of them in the woods in Calgary, Alberta on a euphorbia plant.  I couldn't find them on anything else.  I did search the links on your site and had no luck. Thanks,
Ingrid Christensen



Hi Ingrid,
We do have other images of the Leafy Spurge Hawkmoth Caterpillar, Hyles euphorbiae, posted in our archives on our 10 caterpillar pages. This species was introduced from Europe to help control the spread of its food plant, the Leafy Spurge.

Polyphemus Moth Caterpillar
(08/11/2007) Caterpillar
Hello,
Our daughter found this crawling in our backyard in Dripping Springs, Texas (Central Texas).  We thought it might be a type of Luna Moth caterpillar...can you identify?  Notice the patch of blue (both sides). Thanks,
Chip and Nancy Beebe



Hi Chip and Nancy,
It is easy to confuse the Luna Moth Caterpillar with the Polyphemus Moth Caterpillar. This is actually the Polyphemus Moth Caterpillar.

Imperial Moth Caterpillar
(08/11/2007) what is this thing?
we saw this bug/caterpillar today near our pond. it seems almost prehistoric. do you know what kind of caterpillar this is or what it will become? thanks,
jj



Hi JJ,
We have identified so many adult Imperial Moths this year, that it stands to reason we will be seeing plenty of Imperial Moth Caterpillars as well. Your image is the first to arrive. We currently have a photo of the adult Imperial Moth, Eacles imperialis, on our homepage.

Four Horned Sphinx Caterpillar
(08/11/2007) What is this
Hello.
I found this at the Road America race track in Elkhart WI. It is about three inches long.
Thank you for your help.
Paul Gehrman



Hi Paul,
This is a Four Horned Sphinx Caterpillar, Ceratomia amyntor. It is also known as the Elm Sphinx since the caterpillar has a preference for elm tree leaves. They also eat birch, basswood and cherry.

Viceroy Caterpillar
(08/08/2007) Strange Caterpillar
Hello,
First of all I know you've heard this a million times but I love your website, it is more encompassing than any bug identification book. Anyway, I ran across this little caterpillar today and don't know what it is, I would be thankful if you could identify it for me. I may keep it and see what it turns into if you can't. Its about an inch long and was found on a wild willow tree near my pond. Thanks in advance.
Eric M.



Hi Eric,
Your caterpillar is most definitely in the genus Limenitis. It is a dead ringer for a Viceroy Caterpillar image on BugGuide. The Viceroy Butterfly is best known for being a mimic of the Monarch. In human society, that would be termed an imposter.

Cinnabar Moth Caterpillar
(07/31/2007) Caterpillar
Hi Bugman,
We saw these caterpillars on Prince Edward Island (Canada) recently & assumed they' be in our Audubon guides but are not. Have just found your web-site and love it !  Can you tell us what these are? Thanks.
Christine & Norman



Hi Christine and Norman,
Though your photo is blurry, this looks to us like a Cinnabar Moth Caterpillar, Tyria jacobaeae. According to BugGuide: "Introduced from Europe as a control for introduced weedy Ragwort, the host plant for its caterpillars, which is toxic to livestock." The interesting thing is that BugGuide only reports this species from California, Oregon and Western Canada, as does the Butterfies and Moths of North America site. You might want to check with your local department of agriculture to see if the species has been introduced to your area.

Milkweed Tussock Moth Caterpillar
(07/30/2007) help!!!!
Just happened on to your site a couple months ago, and have been raving abt. it to anyone that will listen!!!  Great job and service you do.  Now, for my bug, er, caterpillar...I found him eating my butterfly weed the other day, and I'm thinking he must be a pest.  I brought one of the larvae in when I first found it and it immmediately spun a cocoon...now I'm wondering if I should get rid of it....can you tell me what this is going to be?   Thanks, in advance, for your great service!
Pat, St. Louis



Hi Pat,
This is a Milkweed Tussock Moth Caterpillar or Milkweed Tiger Moth Caterpillar, Euchaetes egle. If the caterpillars are plentiful, they may defoliate the host plant. The adult moth has unmarked grey wings and yellow spots on the body.

Pandora Sphinx Caterpillar
(07/29/2007) caterpillar?
Hello! We live in Iowa and came across this bug yesterday along a bike trail. Could you tell me what it is? Thank you!!
Elizabeth



Hi Elizabeth,
This is a Pandora Sphinx Caterpillar. Judging by the number of adult moth photos we received this year, we expect your photo to the the first of numerous requests for the caterpillar identification this season. Grape is one of the food plants for the larva and your specimen appears to be be feeding on grape.

Stinging Caterpillar from Belize
(07/25/2007) caterpillar
Hello, Let me start by saying I love your website. I often pull it up and browse through all the new bugs posted. I found a caterpillar in Belize on a jungle hike. It was in the beginning of July and the little guy, about an inch long, was on the ground. I hope you can identify this caterpillar and tell me what it will turn into. ... Thanks-
Amber
SLC, UT



Hi Amber,
Though we don't know the exact species of your caterpillar, we can tell you it is a Stinging Caterpillar in the family Limacodidae, the Slug Caterpillar Moths.

Hickory Horned Devil: Early Instar
(07/24/2007) Large spiny caterpillar with horns?
Hi
We found this in our back yard and were unable to find it in any of our guide books. Then we searched online and found nothing. Can you tell us what it is? More curious about what it is going to be?? Thanks so much Sincerely
the Braun family in Fredericksburg Virginia



Hi Braun Family,
This is an early instar of the Hickory Horned Devil. What it will be after a few more molts is North America's largest and quite possibly most impressive caterpillar. It will become a bright blue-green behemoth with red horns that resembles a Chinese dragon. The adult moth is also quite striking. It is known as the Royal Walnut Moth or Regal Moth, Citheronia regalis.

American Lady Caterpillar
(07/23/2007) American Lady Caterpillar?
Hi,
I think I've identified this caterpillar from your site as an American Lady (post from S. Texas, May 2007).  The description in my Peterson's Eastern Butterflies seems to confirm it.  They are feeding on licorice plant (Helichrysum petiolare) in a window box outside our living room window in Kansas City.  We've planted Helichrysum many times, but first time we've seen these caterpillars on them.  Can you confirm the ID as an American Lady for me? Great site!  Keep up the good work.
Brett



Hi Brett,
We concur that this is an American Lady Caterpillar, Vanessa virginiensis, and it exactly matches an image on BugGuide. Your high resolution, excellent quality photograph is a welcome addition to our site.
