Achemon Sphinx Moth: Essential Facts for Enthusiasts

The Achemon Sphinx Moth (Eumorpha achemon) is a fascinating and fairly uncommon creature found in various habitats worldwide.

As a nocturnal moth, it can be quite a sight to behold during its active period, which typically occurs from late spring to midsummer.

These moths are known for their captivating appearance, sometimes showcasing a wingspan of 3 to 4 inches.

Besides, their wings have striking shades of light brown, pinkish, and gray. There are elegant dark colors on their forewings 1.

Achemon Sphinx

These moths feed on grapevines and Virginia creeper during their larval stage. As adults, the Achemon Sphinx Moth feeds on nectar from flowers, using its long proboscis to hover and slurp up this sweet treat 2.

In the natural world, these moths play a crucial role as pollinators while going about their nightly feeding routines.

Identification of the Achemon Sphinx Moth

Physical Features

The Achemon Sphinx Moth, also known as Eumorpha achemon, is a fascinating species. They possess:

  • Furry legs: Adults have noticeably hairy legs which help in their movement.
  • Wings: Their unique wing patterns contribute to their identification.
  • Color: They exhibit a range of colors, primarily pink and brown hues.

Color and Markings

An adult Achemon Sphinx Moth displays varied coloration and markings:

  • Light brown to dark brown: Their colors can range from light to dark brown shades.
  • Pink hue: Some individuals may exhibit a pinkish hue across their wings.

Wingspan and Size

Achemon Sphinx Moths have sizeable wingspans and distinct features:

  • Wingspan: Their wingspan ranges between 3.5 to 4 inches (9 to 10 cm).
  • Forewings: The adults possess elongated and rectangular forewings.
  • Hindwings: The hindwings are shorter and rounded.
  • Dark brown patches: Both forewings and hindwings can display dark brown patches that help with camouflage.

Below is a table showing the physical features of the moth.

Wing markingsDark brown patches on both forewings and hindwings

Lifecycle and Behavior

Egg Stage

The Achemon Sphinx Moth (Eumorpha achemon) begins its life as a tiny, round egg, usually laid on host leaves such as wild grape or woodbine. The eggs hatch after just a few days.

Caterpillars and Larvae

The larvae of the Achemon Sphinx Moth, also known as hornworms, go through several growth stages:

  • First instar: Bright green, small, and highly active
  • Later instars: Develops distinct color variations, ranging from green to orange to brown

Caterpillars mainly feed on leaves of grapevines and woodbine. Although they’re not considered a significant pest, they can cause minor damage to host plants.

Pupa Stage

When caterpillars reach full size, they pupate in the soil. Pupa is a resting stage where the transformation into an adult moth occurs.

Achemon Sphinx Caterpillar

Adult Moth and Mating

Adult Achemon Sphinx Moths have a large wingspan (3 to 4 inches) and are characterized by:

  • A large, stout body, up to 2 inches long
  • Primarily nocturnal and crepuscular behavior
  • Active mostly during late spring and midsummer

During their short adult lifespan, they mate, lay eggs, and continue the lifecycle.

Feeding Habits and Flight Pattern

The Achemon Sphinx Moth feeds on nectar from various flowers, using its long proboscis.

They also feed on grapevine leaves, but they are not considered garden-destroyers since their populations don’t usually reach pest levels3. Some key aspects of their flight pattern include:

  • Fast and agile flying, resembling hummingbirds
  • Hovering while feeding, making them efficient pollinators

Habitat and Distribution

North America

The Achemon sphinx moth (Eumorpha achemon) is a member of the Sphingidae family, commonly known as sphinx or hawk moths.

They are found throughout North America, including the United States, Mexico, and Southern Canada, and are most active between June and August.

Mexico and United States

The distribution of Achemon sphinx moths spans across Mexico and the United States2.

In the US, they are prevalent in states like Florida and California, where grapevines are abundant.

Southern Canada

In Southern Canada, Achemon sphinx moths are part of the more than two dozen native sphinx moth species.

Though not as common as the white-lined sphinx moth (Hyles lineata), they can be found spanning the North American continent4.

Characteristics of Achemon Sphinx Moths:

  • Family: Sphingidae
  • Pollinators
  • Most active between June and August
  • Caterpillars feed on grapevine leaves

Host Plants and Impact on Agriculture

Virginia Creeper

Achemon sphinx moth larvae have been known to feed on Virginia creeper, a common plant that provides valuable nectar for various species.

These plants provide a substantial food source for achemon sphinx moth larvae.

However, this relationship doesn’t necessarily have a negative impact on Virginia creeper population, as the plants can tolerate some feeding by the larvae.

Vineyards and Grapes

Achemon sphinx moth larvae also feed on grapevines (genus Vitis) found in vineyards.

In viculture, controlling pests like the achemon sphinx moth is essential for grape production. A few notable impacts on grapes include:

  • Larval feeding causes damage to grape leaves and vines
  • Torn leaves can affect overall plant health and grape yields

Although this species may cause some detrimental effects on vineyards, they are not typically considered a severe agricultural pest.

Honeysuckle and Other Plants

Besides Virginia creepers and grapevines, achemon sphinx moth larvae are known to consume other plants such as honeysuckle and some orchid species in the Eumorpha genus.

Conservation Status and Threats of Achemon Sphinx Moth

NatureServe Conservation Status

Regarding its conservation status, the Achemon sphinx moth is currently considered:

  • Secure in terms of its population and range
  • Not classified as an endangered or threatened species

Predators and Threats

Achemon sphinx moths face a few natural predators, and one of the well-known ones is birds. Here are some features of these moths, that make them potential prey:

  • Their size and fat content make them an appealing meal for birds
  • Markings and colors, along with their stripes, make them more visible to predators

However, the Achemon sphinx moth uses some defensive mechanisms to deter these predators, such as:

  • Rapid and erratic flight patterns
  • Feeding at night, reducing the likelihood of encountering bird predators

Conclusion

The Achemon Sphinx Moth (Eumorpha achemon) is a captivating and relatively rare species found in various habitats worldwide.

With its striking appearance and nocturnal habits, it provides a fascinating sight during its active period. These moths play a crucial role as pollinators, contributing to the natural ecosystem.

Although they may feed on grapevines and other plants, their impact on agriculture is generally considered moderate, and they are not classified as a severe agricultural pest.

It’s important to understand their conservation status and potential threats and ensure their preservation in the ecosystem.

Achemon Sphinx Moth – Letters from Readers

The Achemon Sphinx Moth is one of the most famous insects that our readers talk about and ask to know about. Over the last two decades, we have received dozens of emails from our readers asking us to identify this beautiful insect.

We have reproduced some of the best ones with some beautiful images for you to have a look.

Letter 1 – Achemon Sphinx

Subject: Dead leaf moth
Location: Albuquerque, New Mexico
June 30, 2012 4:13 pm
First of all, thank you for your labor of love in maintaining this site. I don’t visit regularly – just every time I see something unusual and want to learn about it.
I found this moth clinging to the door frame of the house, middle of the afternoon (June 30, 2012) about 12-inches above the ground. The wingspan, side to side, is 2.75 inches. I would suspect it just pupated and is drying its wings, except there is only concrete below – no dirt. It could have crawled there but I don’t see an empty case hanging anywhere.
Camouflage is so good I actually thought it was a dead leaf snagged in a spider web. The seeming appearance of openings and curled texture at the ends of the wings is all done with color shading. Structurally, the wings are flat and smooth.
It is very calm and has not moved when we put a camera within 4 inches of it, a ruler just below to measure, or closed the door. Perhaps an instinctive behavior to avoid attention, or maybe it is nocturnal – waiting for night.

What is this? Is it a butterfly?
July 31, 2009
I have been wondering if this is just some kind of butterfly. I found this in my backyard. I thought it was just a leaf, but the only tree I have in my yard is a pine tree. It is summer time as well, so there are not many dead leaves around right now, which is what this looks like.
Do you have any ideas what this could be?

Hi Brooks,
This is actually an  Achemon Sphinx, not a Pandora Sphinx, but your confusion is understandable since both are in the same genus
Eumorpha.  Also, the Achemon Sphinx is in the same family as the Tomato Hornworm, but they feed on different plants, and the mature caterpillar of the Achemon Sphinx lacks a horn, as you can see in this image from our archives.

I think this is a Achemon Sphinx catapiller. It’s very large! I live in Regina, Saskatchewan. When I first found it, it was a very pale beige. Within an hour it turned dark beige, by morning it was reddish.
It has a fake ”eye” on it’s back end with white markings along it’s sides.
If this is indeed what I think it is, is this common in Saskatchewan? I’ve never seen one before.

Hi Darlean,
We agree that this is an Achemon Sphinx Caterpillar, and the fact that it darkened most likely indicates that it is preparing to pupate.  The Sphingidae of the Americas Saskatchewan page lists the Achemon Sphinx, but there is no information on its local population.  On the Sphingidae of the Americas species page, Bill Oehlke writes:  “This species is not often seen in Manitoba, but can be quite common further to the south in most of the United States.”  We are speculating that the same might apply to Saskatchewan.  There must be a larval food plant nearby, and providing a source of food is a good way to ensure that a species will proliferate in a given area.  According to the Sphingidae of the Americas:  “Eumorpha achemon larvae feed upon Grape (Vitis), Virginia Creeper (Parthenocissus quinquefolia) and other vines and ivies (Ampelopsis).”  Since the species is not common in Manitoba, Bill Oehlke might be interested in your Saskatchewan sighting, so we are copying him on this response.

He was found on a grape vine but there are many trees nearby as well – including Cottonwood and Aspen. I don’t see a horn, but it looks like he’s thinking of making a cocoon so I don’t know if they pull their horns back as they prepare for that. I don’t see any hair – he’s very smooth.

Sphinx moth??
Hello,
We found a large chrysalis (3″ long) in the wood mulch in my back yard in Fort Collins, CO two weeks ago. We brought it indoors where it laid for two weeks in my five-year-old daughter’s butterfly habitat. Yesterday, this moth emerged (just when we’d about given up hope that it was actually alive) and tonight we released it where it was found. We’re certain that it is some sort of sphinx moth, but we’re not sure what kind. We’re hopeful that you will tell us it is not going to lay eggs on our nearby tomato plants! The moth’s wingspan is 2.5-3 inches, and when it flies, you can see pink beneath the wings. Thanks for your great website and for your help in identifying our lovely friend!

Sphinx Moth?
Hi, great site.
This is Mike from the panhandle of Nebraska, i went outside to smoke and saw this on the door jam to the outside door. When I caught him I thought he was yellow and black, than put him in a freezer for two days. He some how lived through it and allowed me to take photos. Is it possible that freezing him took the color out, or did I think he was yellow? Anyway the funniest part of the story is letting him go wild again…he flew 10 ft, than turned around, and landed on my pant leg. As soon as I let him go again he flew off about 50 ft. to have a robin swoop down and get him.
Thanks much,
Mike

Hi Mike
The colors on your photo are very consistant with the Achemon Sphinx, Eumorpha achemon. The underwings do have some pink coloration. Many wildlife photographers cool insects by refrigeration before taking photographs.

large moth
June 6, 2010
This insect was clinging to a woody stem that I clipped. There is a lot of leaf litter and mulch in this area, and the camouflage is very good. This was on 6/4/10 about mid-day. The insect never attempted to fly away, and it looks as though part of the cocoon is still on it’s head. It was about 2 inches long, though I did not measure it. I plant lots of natives in my yard and often find interesting insects.

Achemon Sphinx

Dear R. Lee,
Your moth is an Achemon Sphinx and you may read more about this species on Bill Oehlke’s excellent website where he indicates:  “
Those who first published descriptions and assigned scientific names to many insects, simply chose names of biblical or mythological origin without any real descriptive qualities. Their purpose was simply to set a standard for purposes of identification by assigned name. On some occasions, names, mostly of Latin or Greek origin, were chosen to signify a particular character of the genus or of an individual species.  The genus name ‘Eumorpha’ means well-formed.In Greek mythology, Achemon and his brother Basalas were two Cercopes who were constantly arguing. One day they insulted Hercules, who tied them by their feet to his club and marched off with them like a brace of hares.

Achemon Sphinx

Hi Jeremy,
Your observations that your moth looked like a Pandora Sphinx,
Eumorpha pandora, was a good hunch since your moth, the Achemon Sphinx, Eumorpha achemon, is in the same genus.  Though they are different species, the two members of the genus Eumorpha share many physical similarities and they also share a portion of their ranges.  You can read more about the Achemon Sphinx on Bill Oehlke’s excellent website.  Your shot showing the underwings is wonderful for identification purposes.

Thank you for your help in identifying the moth and for the extra knowledge with it. I really do appreciate it.

Dear Sandersons,
This is the caterpillar of an Achemon Sphinx.  According to The Sphingidae of the Americas website, it is rare in Manitoba.  We will contact Bill Oehlke so that he can record your sighting.
  The behavior you describe indicates this individual is preparing to pupate, which they do underground.  Caterpillars lose interest in eating prior to metamorphosis and they search for a suitable location.  Pupating underground enables the Achemon Sphinx to survive the harsh northern winters.

Hi Randy,
You are correct that this is a Sphinx Moth Caterpillar even though the Achemon Sphinx Caterpillar lacks the typical feature distinguishing the larvae of the Sphinx Moths, a caudal horn.  In its earlier instars, the Achemon Sphinx does possess a caudal horn, but it is shed prior to the final instar and instead of a horn, the Achemon Sphinx has a caudal bump.  It appears that might be a few unripe grapes on the ground next to your caterpillar.  Grape leaves are a favored food of the Achemon Sphinx Caterpillar.  You can read more about the Achemon Sphinx on the Sphingidae of the United States website.

Hey  Daniel,
Thanks, that’s great to know. We see those Sphinx moths around the yard. We found this little feller under the  grape vines on the pergola.  (Knocked down by the raccoons.). The read they are partial to grape vines.  I put him back up there.

September 19, 2013 4:26 pm
I saw this large grub thing on my patio with a stick in its moth and not moving much. I called to my children to see this amazing creature. My oldest son pics up the end of the stick and there were these beak like jaws wrapped around this stick. As I look closer the stick was very long and had splintered through a segment of its belly (ouch!) So my sun held the grub and pulled the stick up and out of this poor creatures body. We then released it into the ivy in our yard. I had no explanation for my children, what kind of creature it was, why it has one eye on top of its head and what the few long ”hairs” on the body are for? So I ask you Bug Man what kind of bug is it. I had seen a similar creature on the same patio but last year. It had no eye on its head but it was white as snow and about as large as a garden hose in diameter and about 8 or 9 in long. Are they similar species? My kids love them and they are an amazing testament to nature. There are so many beautiful creatures that are over looked too often. My children love to find ”new” creatures and name them. They believe they have found many new species of insects. Bug Man if you could give me a lot of info on these creatures I would appreciate it. My son is going to do a report on the creature he saved of course once he knows what it is. Thank you for your time.

Achemon Sphinx Caterpillar
Achemon Sphinx Caterpillar

Dear Mom with no answers,
One Eyed Jake is an Achemon Sphinx Caterpillar in the moth family Sphingidae.  Like other caterpillars in the family, it begins its life with a caudal horn.  Like several other relatives, it loses its horn prior to its final molt and what you have mistaken for an eye on its head is actually a caudal bump on the tip of the abdomen.  The caudal bump might fool a predator like a bird into thinking an otherwise tasty caterpillar was a predator like a snake.  Additional information for your son’s report can be found on BugGuide and the Sphingidae of the Americas websites.

Dear Schonemans,
The folks around there who told you these are Hornworms are correct, but they are atypical Hornworms known as Achemon Sphinxes that loose the caudal horn during the final molt between the fourth and fifth instars, and instead of a caudal horn, they are left with a caudal bump or caudal eye.
  Prior to shedding the horn, the Achemon Sphinx Caterpillar sports a prominent, curved horn that is significantly longer and thinner than the horn of most Hornworms.  According to the Sphingidae of the Americas site:  “Eumorpha achemon larvae feed upon Grape (Vitis), Virginia Creeper (Parthenocissus quinquefolia) and other vines and ivies (Ampelopsis).  Larvae get quite large and occur in both a light (green) form, a reddish-orange form, and a darker (tan/brown) form.”

Very unusual insect, and quite large, I’ve never seen anything like it.

Achemon Sphinx Caterpillar
Achemon Sphinx Caterpillar

Dear Tracy,
The Achemon Sphinx Caterpillar,
Eumorpha achemon, in your image is the only member of its genus found in Oregon.  It is a member of the Hawkmoth or Sphinx Moth family Sphingidae, and the caterpillars from this family are called Hornworms.  The Achemon Sphinx Caterpillar is a little unusual among hornworms because it loses its horn as the caterpillar grows and molts, and all that remains is a caudal bump which you likened to an eye.  This may serve as protective mimicry, and its ability to retract its head, which you also observed, is a defense mechanism as well.  According to the Sphingidae of the Americas site, food plants include:  “Parthenocissus quinquefolia Virginia creeper, Vitis Grape, Ampelopsis Vines and Ivies” so we are guessing there is one of those plants near where the sighting occurred.

Hello~
I live in Northern California (Redding –Shasta County)
I’m in need of assistance identifying this caterpillar/worm.
He looks similar to a tomato worm with the exception of his color and no horn on his rump.
My SO claims he is indeed a tomato worm but has a pinkish color because he’s been eating our purple grapes. I say no. If that was so… tomato worms would be red 😉
Please help me be right!! He hates that… 🙂

Dear Little T,
You were right to notice the similarities between your caterpillar and that of the Carolina Sphinx or Tobacco Hornworm, one of two species that feed on the leaves of the tomato, because they are in the same family.  Your caterpillar is that of an Achemon Sphinx,
Eumorpha achemon, a species that feeds on the leaves of grapes.  Caterpillars often have coloration that camouflages them while they feed, but the color is not a result of the pigment in the food.  So, you win.  Go rub it in.

Hello!
I was hiking in the northern side of Mt Diablo State Park (San Francisco Bay Area) in late April when I came across this fellow on the Eagle Peak trail near some oak and pine trees (~1000 feet elevation). Its head end was light red, its body mostly grayish brown with subtle horizontal bands and two symmetrical vertical yellow stripes, and its rear end had a distinct yellow and black “eye” marking. About as big as my pointer finger (see photo with shoe for scale). I’ve never seen anything like it; it’s definitely not a swallowtail, and I’m pretty sure it’s not a moth. Any ideas?

Achemon Sphinx Caterpillar

Dear Kitty,
This is a Hornworm in the family Sphingidae, and most caterpillars from this family have a caudal horn.  The genus
Eumorpha is unusual in that many species in the genus lose the caudal horn as fourth or fifth instar caterpillars.  A common California species is the Achemon Sphinx, Eumorpha achemon, but your aerial view does not reveal features that generally help us to identify the species.  That stated, we did find an aerial view posted to BugGuide, so we are relatively confident our identification is correct.  The Sphingidae of the Americas site may provide additional information you find interesting.  We also learned of Sphingidae of the Americas that the Vine Sphinx, Eumorpha fasciatas is a rare stray in California, and it has a variably colored caterpillar that also lacks a caudal horn, but we are still leaning toward the Achemon Sphinx.

Hi Daniel-
Thank you for the information! This is very helpful. What a beautiful moth! Maybe I will get to see one of those in the coming weeks. Thanks again!

Achemon Sphinx Caterpillar

Dear Jay,
Your Hornworm in the family Sphingidae is somewhat unique in that it is lacking a caudal horn, and has instead a caudal bump where the horn has been shed during molting.  Most members of the genus
Eumorpha share the trait of having a caudal bump instead of a caudal horn.  Your individual is the Pandorus Sphinx, Eumorpha pandorus, and you can read more about it on Sphingidae of the Americas where it states:  “In mature larvae the abdomen has a small white to yellow spot on the anal segment and a single small dot on each of the first two abdominal segmenst and large oval spots around each spiracle on segments three through seven. The whiplike horn of early instars is replaced with a button in the last instar. There is black speckling on the dorsal surface of the thorax and anterior abdominal segments.  When disturbed, the larva quickly retracts the head and first two segments of the thorax into the swollen, third thoracic segment.  There are tan to orangey-brown to almost black as well as green larval forms.”  The Pandorus Sphinx Caterpillar is perfectly harmless, and the adult Pandorus Sphinx is a beautiful moth.

Achemon Sphinx Caterpillar

Dear Keyes fam,
We especially love your aerial or dorsal view of this Achemon Sphinx Caterpillar because it shows how effectively the caudal bump resembles an eye, making this harmless caterpillar take on the appearance of a threatening snake, at least to birds or other predators that might find this fat, mature caterpillar to be a toothsome feast.  According to Sphingidae of the Americas:  “Immature larvae have the characteristic horn-like tail which drops off (i.e., does not develop) after the fourth instar.  Feeding lasts for three to four weeks and full grown larvae leave the host to pupate in undeground [sic] burrows.”  The big mystery to us is how it ended up on the beach.  Perhaps a nearby garden is growing grapes or another preferred food plant and it left the plant to pupate, when it was snatched by a bird that began to carry it over the sand.  The caterpillar then thrashed about and perhaps the false eye startled the bird and it dropped dinner in the dunes.

Achemon Sphinx Caterpillar
This is great! Thank you very much. We were surprised by the size, color, and that it was on the beach. Our theory was also that a bird may have dropped it there. We appreciate your help with the identification!
Oh, we have another question. What are the white squiggly things that run the length on each side? And do they serve a purpose? Thank you!!!!!
 
The markings on the side may help camouflage the caterpillar while it is feeding in dappled light.

Dear Sue,
This is an Achemon Sphinx Caterpillar, a member of the family with caterpillars commonly called Hornworms.  Your particular species, in fact many members of that genus, shed their horn before attaining full size, and there is a caudal bump where the caudal horn was located.  The caudal bump does resemble an eye.

Hi Daniel – thanks so much!  I discovered the retractable head ( how weird ) when it started to move. I had it’s ends mixed up…  I hope it sticks around when it morphs.

Large Caterpillar on our grapevine
Hello Bugman.
My daughter found this large Caterpillar, munching the leaves on our grapevine, at the side of the house. We live in Southern California. We believe it is a species of Hawk Moth; however we are struggling to find the correct ID within our insect book. It has a ‘false’ eye on it’s tail end. Please help us with our mystery. Thanks.

Some type of sphinx moth caterpillar?
Ridgecrest, CA (Mojave Desert), found exactly as pictured, today, in graveled area next to house. It doesn’t fit the White-Lined Sphinx Moth, which I know we have in the area. About 3.5 in long, 0.5 in diameter. I perused a couple of pages on your site and did not find any match, especially that central eye-like marking. Thanks,
Jean

Hi Jean,
This is an Achemon Sphinx Caterpillar, Eumorpha achemon. The caterpillars feed on grape leaves, Virginia creeper and other vines.

Ed. Note:

While subclassifying our caterpillar archive, we realize we did not link to Bill Oehlke’s page on the Achemon Sphinx, nor mention the unusual coloration of this specimen.  This species usually has a brown, orange or green caterpillar, and this pink specimen is a bit unusual.

Achemon Sphinx Caterpillar

Hi Pat,
Just last week we posted another photo of this particular color morph of the caterpillar of an Achemon Sphinx,
Eumorpha achemon, which we had identified on Bill Oehlke’s website Sphingidae of the Americas.  Your caterpillar will metamorphose into a lovely Hawkmoth. Your photo nicely illustrates the caudal bump where typically the caudal horn is situated on most Hornworms, a common name given to the caterpillar of Hawkmoths.  Many of the species in the genus Eumorpha shed their caudal horns in the early instar stages of the caterpillar so the mature caterpillar is hornless.

Thank YOU sooo much for YOUR response.
I got several shots of this caterpillar and even got a movie of it on my camera. It was moving rather quickly across the road.
Now I will look up the Hawkmoth and see what it looks like.
Again thank you.

Achemon Sphinx Caterpillar

Dear Puzzled bug observer,
Your caterpillar is an Achemon Sphinx, a variably colored hornworm that is unusual in that the later instar caterpillar loses its namesake horn.  Your individual is a match to several images on BugGuide, though the Sphingidae of the Americas website does not picture this color variation.  Rosemary is not listed as a food plant.  Grape and other vines are typical food plants for caterpillars, so we can’t help but wonder if a grape vine was growing near the rosemary.

Yes, the rosemary is growing directly next to a Thompson seeless grape vine!!  Thank you for the references and name so we can further research him.
We appreciate your quick response.  Sincerely,  no-longer-puzzled bug observer

Achemon Sphinx Caterpillar

Dear Mark,
This is the caterpillar of an Achemon Sphinx.  In addition to Virginia Creeper, they feed on the leaves of Grape and a few other vines.  The caterpillars of Sphinx Moths are known as Hornworms, however, a few species, including the Achemon Sphinx, lose the horn in an early molt.  All that remains of the caudal horn in the Achemon Sphinx Caterpillar is a Caudal Bump that might be mistaken for an eye by a predator.  You may read more about the Achemon Sphinx on the excellent Sphingidae of the Americas Website.

Daniel,
Thank you very much!!!!  I really appreciate your knowledge and you taking the time to make me smarter!

Achemon Sphinx Caterpillar

Dear Bu Girl,
Though your photo does not show the markings on the side of this individual very well, we believe you have photographed the caterpillar of the Achemon Sphinx.  Sphinx Moth caterpillars are called Hornworms because they usually have a caudal horn, however, the Achemon Sphinx sheds its caudal horn as a young caterpillar, leaving a caudal spot or “eye” that is barely visible on the right side of your photo.  According to the Sphingidae of the Americas website, the caterpillar of the Achemon Sphinx feeds upon:  “Grape (Vitis), Virginia Creeper (Parthenocissus quinquefolia) and other vines and ivies (Ampelopsis).”

Achemon Sphinx Caterpillar

Hi Karen,
We believe this is an Achemon Sphinx Caterpillar, and it appears that it may have left its food plant and begun to hunt for a likely spot to dig into the earth and pupate.  The Sphingidae of the Americas website indicates that there are no reported sightings of the Achemon Sphinx in Saskatchewan, though it is suspected to range in the region.  Because of that, we are copying Bill Oehlke on this reply and he may request permission to use your photograph as well as to include your sighting data so he can update the status of the Achemon Sphinx in Saskatchewan.  You can read about the Achemon Sphinx on the Sphingidae of the Americas website.

Hi Daniel,
Yes, that one is Eumorpha achemon. Thanks for referral.

Here is a bunch of pictures of the same caterpillar I found on a path near Snow on the mountain and woodbine. Is it a pandora sphinx caterpillar? Should I let it live?
Tara

Tara,
Why do you want to kill the Achemon Sphinx Caterpillar? Was the path in your garden or a public park? Most public parks have laws about destroying wildlife. Your letter has filled us with anxiety.

I put it back near the woodbine and saw it about 1/2 hour later on a different part of the path going in the opposite direction toward my backyard. This was early this morning, haven’t seen it since but I am pretty sure it is alive and well. It absolutely freaked me out and made me feel a bit nauseated but be calm and sleep well…it didn’t meet it’s maker at my hands. My woodbine needs trimming back anyway. Unfortunately it didn’t stay there. It seemed either headed to the apple tree or my primrose and columbines. Does it like hostas? If it does like hostas, it’s destiny, if I ever seen it again, may change. Thanks for identifying it.
Tara

Hi again Tara,
We beg you to reconsider. We just posted a photo of a beautiful adult moth and they help pollinate your garden.

Thanks for your humor, I am just teasing, it won’t die by my hands and I warned my neighbor not to squash it. The adult moth is neat looking. I looked it up and found some data from ND about being beneficial. I’m in Rapid City, SD, lived here 8 years and never seen anything like it on the woodbine before. What’s the art project? Are you collecting the photos or just weird human responses? I enjoyed the unnecessary carnage link.
Tara

The art project deals with interaction (much like this exchange) and about global community. The world wide web brings people together, and we don’t just mean online dating, in ways that were never possible before.

  6. One more distinctive characteristic I forgot to mention yesterday: there are six pairs of lateral ornaments in this species’ caterpillar (Eumorpha achemon, as pictured on the photo) instead of five (E. pandorus); and the latter one might rather be restricted to the eastern parts of the continent, but I am not sure whether it could be spread to the western areas as synanthropic species in the meantime… They cooccur in the eastern half of the territory. – A fascinating genus of hawkmoths with the larvae pupating in underground chambers, which is typical for many Sphinginae, but quite unusual for the Macroglossinae…
