Life Cycle
Eggs
The life cycle of the Bedstraw Hawk Moth (Gallium Sphinx) begins with the eggs. These eggs are tiny and typically laid either singly or in small groups on the leaves of their host plants. Some common host plants for the Bedstraw Hawk Moth include:
- Bedstraw (Galium)
- Willowherb (Epilobium)
Caterpillars
Once the eggs hatch, the larvae, or caterpillars, emerge. These caterpillars have several distinct stages of growth, called instars, with each stage having a specific appearance. During their larval stage, Bedstraw Hawk Moth caterpillars feed on the leaves of their host plants to grow and develop.
As the caterpillars mature, they may display one of two different color forms:
- Green
- Brown
Pupa
After the caterpillars have reached full growth, they enter the pupa stage. During this stage, they transform into a chrysalis, which is a protective casing that encloses them while they undergo metamorphosis. The pupa stage is typically spent in the soil or under leaf litter, providing camouflage from predators.
Adults
Once the metamorphosis is complete, the adult Bedstraw Hawk Moths emerge from their pupae. Adult moths have a few notable features:
- Long, pointed forewings
- Large, heavy bodies
- Long proboscis (mouth tube) for feeding on nectar
Some common predators of Bedstraw Hawk Moths in their various life stages include:
- Bats
- Birds
- Wasps
- Spiders
- Shrews
Adult moths are important pollinators, as they feed on nectar from flowers, aiding in the process of pollination.
Distribution and Habitat
Europe and North America
Bedstraw Hawk Moths (Hyles gallii) have a widespread distribution, spanning across Europe, North America, and Asia. In Europe, they can be found from the Arctic Circle down to the Mediterranean, while in North America, their range extends from Alaska to Quebec.
Asia and Africa
In Asia, their distribution stretches from Japan and Central Asia to parts of western Africa. These moths prefer warm forest edges, sandy heaths, and calcareous places where they can find an abundance of flowering plants during dusk and night.
Forest Edges and Sandy Heath
Some typical habitats for Bedstraw Hawk Moths include:
- Warm forest edges
- Sandy heathlands
- Open areas near sea level
These habitats provide plenty of flowers for the moths to feed on, such as catchweed bedstraw, which can be found in shady, moist conditions.
Plantations and Calcareous Places
In addition to forest edges and sandy heaths, Bedstraw Hawk Moths can also be found in:
- Plantations
- Calcareous environments
These environments offer a diverse range of flowers and plants for the moths to feed on.
Comparison of Bedstraw Hawk Moth Habitats:
Habitat | Environment | Example Locations |
---|---|---|
Forest edges | Warm, open areas with abundant flora | Europe, North America, Asia |
Sandy heaths | Open sandy areas with heathland vegetation | Central Asia, Japan |
Plantations | Human-created habitats with diverse plant life | Europe, North America |
Calcareous places | Habitats rich in calcium carbonate soils | Mediterranean, parts of western Africa |
Overall, the Bedstraw Hawk Moth can adapt to a variety of habitats, making it a versatile and widespread insect species.
Diet and Host Plants
Feeding Habits
The Bedstraw Hawk Moth (Hyles gallii) is a species of Sphingidae, known for its beautiful appearance and fascinating feeding habits. These moths primarily feed on nectar from various plant species. As caterpillars, they consume the leaves of host plants, which can include various species within the Galium, Fuchsia, and others.
Galium and Fuchsia
Two primary host plants for the Bedstraw Hawk Moth caterpillars are the Galium (bedstraws) and Fuchsia plant species. For example, they may feed on:
- Galium verum (yellow bedstraw)
- Galium mollugo (white bedstraw)
- Fuchsia species
These plants provide essential nutrients to the developing caterpillars, allowing them to grow and eventually transform into adult moths.
Other Plant Species
In addition to Galium and Fuchsia, Bedstraw Hawk Moth caterpillars can also feed on a variety of other plant species, such as:
- Rosebay Willowherb (Epilobium angustifolium)
- Madders (Rubia spp.)
- Clarkia (Clarkia spp.)
- Enchanter’s Nightshade (Circaea spp.)
- Plantago major (Broadleaf plantain)
Here is a comparison table of some host plants:
Host Plant | Plant Family | Caterpillar Preference |
---|---|---|
Galium verum | Rubiaceae | High |
Galium mollugo | Rubiaceae | High |
Fuchsia | Onagraceae | High |
Rosebay Willowherb | Onagraceae | Moderate |
Clarkia | Onagraceae | Moderate |
Circaea | Onagraceae | Moderate |
Plantago major | Plantaginaceae | Low |
Understanding the diet and host plants of Bedstraw Hawk Moths is essential for conservation efforts and helps gardeners create an optimal environment for these fascinating creatures.
Behavior and Flight Period
Daily Activity Patterns
Bedstraw hawk-moths (Gallium Sphinx) are most active during summer months such as June, July, and August. These moths are known to be crepuscular, meaning they are most active during dusk and dawn. They exhibit a hummingbird-like behavior, using their long proboscis to feed on nectar from flowers.
Seasonal Flight Patterns
During the summer season, Bedstraw hawk-moths have a specific flight period that generally lasts from June to September. This flight period can be divided into two generations:
- First generation: June to July
- Second generation: August to September
These generations are essential for the moth’s life cycle, as they involve the laying of eggs and the development of larvae. The larvae feed on bedstraw plants, which is how they receive their name.
Table: Bedstraw Hawk-Moth Seasonal Flight Pattern
Generation | Flight Period |
---|---|
First | June – July |
Second | August – September |
Bedstraw Hawk-Moth features:
- Crepuscular activity pattern
- Hummingbird-like behavior
- Long proboscis for feeding on nectar
- Two distinct generations during the summer season
- Larvae feed on bedstraw plants
In comparison, hummingbird moths are similar in appearance and behavior to Bedstraw hawk-moths, as they both hover while feeding on flower nectar and exhibit a rich reddish brown color. However, hummingbird moths have shorter tail ends that open up into a fan, distinguishing them from Bedstraw hawk-moths.

Ok I live in fairbanks Alaska it’s almost fall/our winter so you don’t really see all that many bugs around. But we found this guy he’s about 3in long brown with yellow spots and a spine tail thing and his head was the little thing.
Signature: ~Tif
Hi Tif,
Your caterpillar is a Hornworm, the common name given to the caterpillars of the Hawkmoths or Sphinx Moths in the family Sphingidae. Hornworm is a reference to the caudal horn which most all members of the family possess. When we are trying to identify New World Sphingiids, we generally turn to the easily searchable Sphingidae of the Americas Website where you can search by country and state. There are only five species reported in Alaska, which makes the search quite simple. This is the Bedstraw Hawkmoth Caterpillar, Hyles gallii, and the Sphingidae of the Americas site indicates: “Hyles gallii ranges coast to coast in Canada (into the Yukon) and southward along the Rocky Mountains into Mexico. It is also widely distributed throughout Europe and Asia.” One might think that with only five species of Sphinx Moths in Alaska, identification of this caterpillar would be easy, but the identification is complicated by the variations in color among caterpillars, including a green variation and a black morph. You can see a photo of the adult Bedstraw Hawkmoth from our archives.
Letter 2 – Bedstraw Hawkmoth Caterpillar
Strange Caterpillar from the woodpile
Location: Northeastern Pensylvania
February 25, 2011 10:26 am
Hi! Firstly, I LOVE wtb, I just found it a few days ago, and I’m practically obsessed with learning about the different kinds of bugs. I’ve always been a bug lover, and this past fall when I was helping my dad stack wood in the woodshed, when I found two awesome bugs in the course of one day. The first is a beetle looking thing, I thought he was just awesome, So I took him inside and snapped some pictures before I let it back on the woodpile. I’ve lived here my whole life and never seen anything like this! It did pinch ahold of my dad when he was poking it (silly man) and apparently it hurt pretty bad. But he just pulled it off and put it back on the wood, laughing at how dumb of an idea it was to poke it. The second little guy came crawling off one of the logs. It made me a little nervous, as I was ”stung” by a big green spiky caterpillar when I was younger, but all in all he was only concerned with munching on the leaf I put in the bowl for him. He was really cool, and I took him inside the house to photograph him, then let him go back were he was on the woodpile. I never saw what he hatched into though. Any idea what this guy is, and what he may have turned into?
Signature: Liz
Dear Liz,
Thank you for your highly entertaining and very sweet email. Your caterpillar is a Bedstraw Hawkmoth Caterpillar or Gallium Sphinx, Hyles gallii, which we confirmed on the Sphingidae of the Americas website. There you may read a lengthy account of the caterpillar and adult moth including details of its life cycle.
Thanks! 🙂 Mystery solved!

I saw this guy in late July in a shrubby area in the boreal forest while working. He was about 2.5-3 inches long with a distinct red stinger. I have no idea what species this is…
Signature: Chebb
Dear Chebb,
Your speculation that because this caterpillar has a horn, it is capable of stinging is incorrect. This is the perfectly harmless caterpillar of the Bedstraw Hawkmoth, a member of the family Sphingidae that has caterpillars commonly called Hornworms. There are several different color variations to the Bedstraw Hawkmoth Caterpillar including black with spots and green with spots as well as your olive drab example. The Bedstraw Hawkmoth Caterpillar feeds on the leaves of Bedstraw in the genus Gallium and Fireweed in the genus Epilobium. You can read more about the Bedstraw Hawkmoth on the Sphingidae of the Americas website.

Hi Lisa,
This is the first photo we have received of the adult Bedstraw Hawk Moth, Hyles gallii. We have received images of the caterpillar in the past. Bill Oehlke has information on this moth on his wonderful Sphingidae site.
Wow! My photos made the front page of WHAT’S THAT BUG! There’s a wildflower called “Our Lady’s Bedstraw” which when I looked it up, also had the word “galium” in the Latin name, just like the moth does. Matresses must have been filled with this material, which was clearly particularly attractive to this moth… I found these two articles:

Letter 5 – Bedstraw Hawkmoth
Hello Mr. Bugman!
Here are a couple of shots of a moth we discovered in our front yard, in Moose Jaw, Saskatchewan, Canada. There were several of them, seen at dusk, sucking nectar from our petunias. None of us have ever seen a moth such as these, and we are wondering if they are uncommon on the prairies. We have had a very long hot spell this summer – about 6 weeks above 35C, so are wondering if this may have made a difference to the expansion of their range? ‘Would appreciate any comments you might like to send. We have checked your site, and believe these are Striped Morning Sphinx moths. They move exactly like a hummingbird – very intriguing, and anybody we have talked to has never seen such an insect in these parts.
Debbie Thompson
Hi Debbie,
You have correctly identified only one of your moths as a Striped Morning Sphinx, Hyles lineata, a native species. Your other moth is a related species, the Bedstraw Hawkmoth, Hyles gallii. The Bedstraw Hawkmoth is found in North America and Europe. It might be an introduced species.

black horned caterpillar
Hi there,
I ran across this crazy looking specimen today fly- fishing in south-western Alberta on the HIGHWOOD river. It was approximately 2.5 inches long. I thought it was weird that it was sunning itself on a rock a couple of feet from the river. I saw on the site that another person encountered one in British Columbia, but you couldn’t identify it. Have you had any luck since?
Mark
Hi Mark,
Thanks to your letter we did more research and turned to Bill Oehlke’s site. We located what we are 99% sure is your caterpillar, the Bedstraw Hawkmoth. Caterpillars are very variable in coloration. The Bedstraw Hawkmoth or Gallium Sphinx, Sphinx gallii ranges throughout Canada as well as much of Europe. Oehlke writes: “Larvae, which were smooth, shiny, and predominantly black, grew extremely rapidly. They reminded me of warm, black licorice strips in that they were shiny, long and thin, and did not seem to have or exercise much longitudinal muscle strength. “

Hi Daniel,
I sent in the photos of the Giant Ichneumon last week that you are using for the September Bug of the Month. (Thanks, again!)
I thought you might like these two photos I took of a White Lined Sphinx Moth. It was on my phlox one evening. The interesting thing about these moths is, they are not the least bit bothered by having a camera stuck in their faces as they fly about, quite unlike most moths!
KT
Hi KT,
Your action photos are wonderful, but we believe you have misidentified your moth. Rather than the White Lined Sphinx, we believe this to be the closely related Bedstraw Hawkmoth, Hyles gallii. You can compare your images to the photos posted on Bill Oehlke’s excellent website that allows you to search by state or country to try to identify moths in the family Sphingidae. The Bedstraw Hawkmoth is quite common coast to coast in the northern portions of North America throughout Canada and into Alaska as well as the northern portions of Europe and Asia. Bill Oehlke indicates that along the Rocky Mountains it is also reported as far south as Mexico.
Hi Daniel,
Thanks very much for that clarification. I was going by another moth that I saw on your site, which is the stock photo that was posted on August 17. Interesting that they are so similar. The photographs on Bill Oehlke’s site certainly do look like ‘my’ moth. Just for fun, I sent him the same two shots.
KT
Hi again KT,
We should probably have clarified that the Bedstraw Hawkmoth and the White Lined Sphinx are closely related moths in the same genus, hence your understandable confusion.
Hi Daniel,
Yes, they sure are very similar! I did send the photos to Bill Oehlke and this was the result! Very cool!! http://www.silkmoths.bizland.com/Sphinx/vtWindhamsph.htm
It’s nice to know there are others out there who are as interested in these creatures.
Have a great day,

I was wondering what kind of caterpillar this is? What will it turn into? I found it in the grass, what do I feed it?
Signature: Carol
Hi Carol,
In trying to correctly identify your Hornworm, we have also made a correction to our archives. Many years ago we received a photo of a caterpillar with identical markings from Montana, and at that time, we narrowed the possibilities to two species in the same genus, the White Lined Sphinx and the Bedstraw Hawkmoth. At that time the Sphingidae of the Americas did not have an image of a Bedstraw Hawkmoth Caterpillar, Hyles gallii, with this particular color variation, but now it does. We suspect this is the prepupal coloration since many caterpillars change colors just prior to metamorphosis.

Hi Jessica,
We needed to research the initials in your location in order to learn that the Canadian Forces Base (CFB) is located in Wainwright, Alberta, Canada. This harmless caterpillar is a Bedstraw Hawkmoth Caterpillar, Hyles gallii, and you can find wonderful information regarding the species on the Sphingidae of the Americas website. Larvae of the Sphinx Moths or Hawkmoths in the family Sphingidae are known as Hornworms.

Letter 1 – Bedstraw Hawkmoth Caterpillar from Alaska
Whaterpiller?
Location: Fairbanks, Alaska
August 13, 2011 5:03 pm
Ok I live in fairbanks Alaska it’s almost fall/our winter so you don’t really see all that many bugs around. But we found this guy he’s about 3in long brown with yellow spots and a spine tail thing and his head was the little thing.

Hi Tif,
Your caterpillar is a Hornworm, the common name given to the caterpillars of the Hawkmoths or Sphinx Moths in the family Sphingidae. Hornworm is a reference to the caudal horn which most all members of the family possess. When we are trying to identify New World Sphingiids, we generally turn to the easily searchable Sphingidae of the Americas Website where you can search by country and state. There are only five species reported in Alaska, which makes the search quite simple. This is the Bedstraw Hawkmoth Caterpillar, Hyles gallii, and the Sphingidae of the Americas site indicates: “Hyles gallii ranges coast to coast in Canada (into the Yukon) and southward along the Rocky Mountains into Mexico. It is also widely distributed throughout Europe and Asia.” One might think that with only five species of Sphinx Moths in Alaska, identification of this caterpillar would be easy, but the identification is complicated by the variations in color among caterpillars, including a green variation and a black morph. You can see a photo of the adult Bedstraw Hawkmoth from our archives.
Letter 2 – Bedstraw Hawkmoth Caterpillar
Strange Caterpillar from the woodpile
Location: Northeastern Pensylvania
February 25, 2011 10:26 am
Hi! Firstly, I LOVE wtb, I just found it a few days ago, and I’m practically obsessed with learning about the different kinds of bugs. I’ve always been a bug lover, and this past fall when I was helping my dad stack wood in the woodshed, when I found two awesome bugs in the course of one day. The first is a beetle looking thing, I thought he was just awesome, So I took him inside and snapped some pictures before I let it back on the woodpile. I’ve lived here my whole life and never seen anything like this! It did pinch ahold of my dad when he was poking it (silly man) and apparently it hurt pretty bad. But he just pulled it off and put it back on the wood, laughing at how dumb of an idea it was to poke it. The second little guy came crawling off one of the logs. It made me a little nervous, as I was ”stung” by a big green spiky caterpillar when I was younger, but all in all he was only concerned with munching on the leaf I put in the bowl for him. He was really cool, and I took him inside the house to photograph him, then let him go back were he was on the woodpile. I never saw what he hatched into though. Any idea what this guy is, and what he may have turned into?

Dear Liz,
Thank you for your highly entertaining and very sweet email. Your caterpillar is a Bedstraw Hawkmoth Caterpillar or Gallium Sphinx, Hyles gallii, which we confirmed on the Sphingidae of the Americas website. There you may read a lengthy account of the caterpillar and adult moth including details of its life cycle.
Thanks! 🙂 Mystery solved!

Letter 3 – Bedstraw Hawkmoth Caterpillar from Canada
Subject: Stinging Catepillar
Location: 70 km north of Fort McMurray, Alberta
July 30, 2012 11:38 am
I saw this guy in late July in a shrubby area in the boreal forest while working. He was about 2.5-3 inches long with a distinct red stinger. I have no idea what species this is…
Signature: Chebb
Dear Chebb,
Your speculation that because this caterpillar has a horn, it is capable of stinging is incorrect. This is the perfectly harmless caterpillar of the Bedstraw Hawkmoth, a member of the family Sphingidae that has caterpillars commonly called Hornworms. There are several different color variations to the Bedstraw Hawkmoth Caterpillar including black with spots and green with spots as well as your olive drab example. The Bedstraw Hawkmoth Caterpillar feeds on the leaves of Bedstraw in the genus Gallium and Fireweed in the genus Epilobium. You can read more about the Bedstraw Hawkmoth on the Sphingidae of the Americas website.

moth love!
I wonder if you might tell me about this amorous pair. I photographed them in July in Cooperstown New York. Love the website!
Thanks

Hi Lisa,
This is the first photo we have received of the adult Bedstraw Hawk Moth, Hyles gallii. We have received images of the caterpillar in the past. Bill Oehlke has information on this moth on his wonderful Sphingidae site.
Wow! My photos made the front page of WHAT’S THAT BUG! There’s a wildflower called “Our Lady’s Bedstraw” which when I looked it up, also had the word “galium” in the Latin name, just like the moth does. Matresses must have been filled with this material, which was clearly particularly attractive to this moth… I found these two articles:

Letter 5 – Bedstraw Hawkmoth
Hello Mr. Bugman!
Here are a couple of shots of a moth we discovered in our front yard, in Moose Jaw, Saskatchewan, Canada. There were several of them, seen at dusk, sucking nectar from our petunias. None of us have ever seen a moth such as these, and we are wondering if they are uncommon on the prairies. We have had a very long hot spell this summer – about 6 weeks above 35C, so are wondering if this may have made a difference to the expansion of their range? ‘Would appreciate any comments you might like to send. We have checked your site, and believe these are Striped Morning Sphinx moths. They move exactly like a hummingbird – very intriguing, and anybody we have talked to has never seen such an insect in these parts.
Debbie Thompson
Hi Debbie,
You have correctly identified only one of your moths as a Striped Morning Sphinx, Hyles lineata, a native species. Your other moth is a related species, the Bedstraw Hawkmoth, Hyles gallii. The Bedstraw Hawkmoth is found in North America and Europe. It might be an introduced species.
Letter 6 – Another Bedstraw Hawkmoth Caterpillar
My two sons and I found this amazing caterpillar
Hello there, how are ya?
My two sons and I found this amazing caterpillar in the City of Red Deer, Alberta the other week. We are extremely interested in discovering what is called. Would you be able to help us out with this? Thanks & God bless!
William, Kyle & Daddy
Dear William, Kyle and Daddy,
This is the second Bedstraw Hawkmoth Caterpillar photo we received this week. The other was from Alaska.
Letter 7 – Bedstraw Hawkmoth Caterpillar
I live in Anchorage, AK and found this one rainy day on the flightline. We tried to search the internet to find out what it was but had no luck. Can you help?Meghan
Hi Meghan,
The Bedstraw Hawkmoth Caterpillar, or Gallium Sphinx, Hyles gallii , is one of the few Sphinx Moths found in Alaska. It ranges through much of Canada and Northern Europe. More information can be located on Bill Oehlke’s excellent website.
Letter 8 – Bedstraw Hawkmoth Caterpillar
black horned caterpillar
Hi there,
I ran across this crazy looking specimen today fly- fishing in south-western Alberta on the HIGHWOOD river. It was approximately 2.5 inches long. I thought it was weird that it was sunning itself on a rock a couple of feet from the river. I saw on the site that another person encountered one in British Columbia, but you couldn’t identify it. Have you had any luck since?
Mark
Hi Mark,
Thanks to your letter we did more research and turned to Bill Oehlke’s site. We located what we are 99% sure is your caterpillar, the Bedstraw Hawkmoth. Caterpillars are very variable in coloration. The Bedstraw Hawkmoth or Gallium Sphinx, Sphinx gallii ranges throughout Canada as well as much of Europe. Oehlke writes: “Larvae, which were smooth, shiny, and predominantly black, grew extremely rapidly. They reminded me of warm, black licorice strips in that they were shiny, long and thin, and did not seem to have or exercise much longitudinal muscle strength. “
Letter 9 – Bedstraw Hawkmoth
White Lined Sphinx Moth
Location: Saxtons River, VT
September 1, 2010 7:31 am
Hi Daniel,
I sent in the photos of the Giant Ichneumon last week that you are using for the September Bug of the Month. (Thanks, again!)
I thought you might like these two photos I took of a White Lined Sphinx Moth. It was on my phlox one evening. The interesting thing about these moths is, they are not the least bit bothered by having a camera stuck in their faces as they fly about, quite unlike most moths!
KT
Hi KT,
Your action photos are wonderful, but we believe you have misidentified your moth. Rather than the White Lined Sphinx, we believe this to be the closely related Bedstraw Hawkmoth, Hyles gallii. You can compare your images to the photos posted on Bill Oehlke’s excellent website that allows you to search by state or country to try to identify moths in the family Sphingidae. The Bedstraw Hawkmoth is quite common coast to coast in the northern portions of North America throughout Canada and into Alaska as well as the northern portions of Europe and Asia. Bill Oehlke indicates that along the Rocky Mountains it is also reported as far south as Mexico.
Hi Daniel,
Thanks very much for that clarification. I was going by another moth that I saw on your site, which is the stock photo that was posted on August 17. Interesting that they are so similar. The photographs on Bill Oehlke’s site certainly do look like ‘my’ moth. Just for fun, I sent him the same two shots.
KT
Hi again KT,
We should probably have clarified that the Bedstraw Hawkmoth and the White Lined Sphinx are closely related moths in the same genus, hence your understandable confusion.
Hi Daniel,
Yes, they sure are very similar! I did send the photos to Bill Oehlke and this was the result! Very cool!! http://www.silkmoths.bizland.com/Sphinx/vtWindhamsph.htm
It’s nice to know there are others out there who are as interested in these creatures.
Have a great day,
KT
Letter 10 – Bedstraw Hawkmoth Caterpillar
Subject: what kind of caterpillar is this
Location: walnutport pa
July 7, 2012 1:02 pm
I was wondering what kind of caterpillar this is? What will it turn into? I found it in the grass, what do I feed it?
Signature: Carol
Hi Carol,
In trying to correctly identify your Hornworm, we have also made a correction to our archives. Many years ago we received a photo of a caterpillar with identical markings from Montana, and at that time, we narrowed the possibilities to two species in the same genus, the White Lined Sphinx and the Bedstraw Hawkmoth. At that time the Sphingidae of the Americas did not have an image of a Bedstraw Hawkmoth Caterpillar, Hyles gallii, with this particular color variation, but now it does. We suspect this is the prepupal coloration since many caterpillars change colors just prior to metamorphosis.
Letter 11 – Bedstraw Hawkmoth Caterpillar
Subject: unknown Armed Caterpillar
Location: CFB/ASU Wainwright
August 7, 2012 10:39 am
A coworker of mine came across this lovely specimen the other day and I have been unable to identify it. He reported that when he got close the caterpillar began thrashing his spike around as though trying to stab him with his knife and then scurried away suprisingly fast. Any clues as to what this may be would be greatly appreciated!
Signature: Jessica
Hi Jessica,
We needed to research the initials in your location in order to learn that the Canadian Forces Base (CFB) is located in Wainwright, Alberta, Canada. This harmless caterpillar is a Bedstraw Hawkmoth Caterpillar, Hyles gallii, and you can find wonderful information regarding the species on the Sphingidae of the Americas website. Larvae of the Sphinx Moths or Hawkmoths in the family Sphingidae are known as Hornworms. They often have caudal horns and they have developed elaborate defense tactics in an effort to intimidate predators. Your coworker must have been perceived as a predator.

Hi,
Found this caterpillar on some fireweed in my front yard.
Signature: Karelle
Dear Karelle,
This is the caterpillar of the Bedstraw Hawkmoth or Gallium Sphinx, Hyles gallii. You may read all about the life cycle of the Bedstraw Hawkmoth as well as its food plant, fireweed, on the Sphingidae of the Americas website. There are several different color variations for the caterpillar in addition to the olive color you have submitted. Other colors include black and green. Since a family matter requires that we be away from the office this weekend, we are postdating this submission to go live on Friday during our absence.
Thanks Daniel for your prompt and informative reply. I’ve seen the moth here, so I’m glad to recognize the caterpillar stage too.

Dear T. Smith,
This is a Hornworm in the family Sphingidae, and according to the Sphingidae of the Americas site, there are only five species found in Alaska. This is a Bedstraw Hawkmoth Caterpillar, Hyles gallii, and according to the Sphingidae of the Americas site: “Hyles gallii ranges coast to coast in Canada (into the Yukon) and southward along the Rocky Mountains into Mexico. It is also widely distributed throughout Europe and Asia. Ken Philip reports it in Alaska from early June until mid July in the Haines Region and also in Ivotuk Hills near Otuk Creek on the North Slope.”

Insects do not obey any human laws when it comes to crossing borders. The range of the Bedstraw Hawkmoth, according to BugGuide, includes Pennsylvania. The Pennsylvania sightings page of the Sphingidae of the Americas website we cited in our original posted response also indicates that the Bedstraw Hawkmoth is found in Pennsylvania.

Found this one in backyard, but with dark magenta colouring on his body. Genetic mutation or cross-breeding between a different species of caterpillar such as the Pandorus Sphinx?
Most likely a color variation.
My friend sent me a photo of this caterpillar today. It was very pink/purple as it has been feeding on a profusely growing plant called Fireweed.

Why do bedstraw hawk moths have something that resembles a stinger on their behind?? I have one that my daughter found in our driveway.
Are you talking about the caterpillar or the moth? Caterpillars have a caudal horn that is not a stinger.
It is solely a defense mechanism for predators. Kind of like our fake cameras outside our home lol.
