Antennae Hairless, with a gradual change in width

In summary, the Lime Hawk Moth has a striking appearance with unique physical characteristics, including a diverse color palette and hairless antennae.

Distribution and Habitat

Geographical Range

The Lime Hawk Moth (Mimas tiliae) is native to England, Wales, and other parts of the UK. It is also widespread across Europe, including regions like France, Germany, and Italy.

Urban and Rural Habitats

The Lime Hawk Moth can be found in various habitats, such as:

  • Parks: These moths often inhabit green spaces in urban areas.
  • Gardens: They can be found in both public and private gardens, benefiting from the abundance of food sources in these environments.
  • Woodlands: Lime Hawk Moths are also present in rural areas, thriving in woodlands where they can find ample shelter and food.

Naturally, these moths are attracted to tree trunks as they provide an ideal resting place for camouflage purposes. In urban areas, they are known to adapt well, often residing in gardens and parks. Although their main habitat consists of woodlands in rural areas, these adaptable moths can live comfortably in urban settings as long as there is an adequate presence of trees and foliage.

Habitat Examples Pros Cons
Parks Green spaces in urban environments Plenty of food sources Human disturbances
Gardens Public and private gardens Diverse vegetation Pesticide exposure
Woodlands Wooded areas in rural regions Ideal shelter Limited food variety

Lime Hawk Moth Life Cycle

Eggs

The Lime Hawk Moth begins its life cycle as an egg laid on the leaves of its host plants. The female moth can lay hundreds of eggs during her lifespan. These eggs are:

  • Small and spherical in shape
  • Yellow-green in color, turning brownish as they mature

Caterpillar Stage

After 7-10 days, the eggs hatch into larvae, also known as caterpillars. Lime Hawk Moth caterpillars have specific features:

  • Green body with white, purple, and reddish markings
  • A pronounced “horn” on their rear end
  • Host plants: lime, birch, elm, and other trees

The caterpillars actively feed on the leaves of their host plants and molt several times throughout their growth.

Pupa Stage

Once the caterpillar reaches its full size, it pupates in the soil. It forms a brown, tough chrysalis during this stage. Lime Hawk Moths overwinter in the pupal stage, ensuring they survive cold months in a protected state.

Adult Moth

In spring, the adult Lime Hawk Moths emerge from the chrysalis. As adults, they have certain characteristics:

  • Green and pinkish-brown wings with intricate patterns
  • Wingspan of 70-80 mm
  • Long proboscis to feed on nectar

Adult moths are most active at night and have a relatively short lifespan of a few weeks. This life cycle then starts anew with mating and egg-laying, usually producing one generation per year.

Feeding and Host Plants

Larval Foodplants

The Lime Hawk Moth (Mimas tiliae) is known for its preference of larval foodplants. As the name suggests, its primary host plant is:

  • Lime (Tilia spp.): Lime foliage provides the main source of nutrition for the larvae.

However, these caterpillars can also be found feeding on a variety of other trees:

  • Elm (Ulmus spp.)
  • Birch (Betula spp.)
  • Alder (Alnus spp.)
  • Plane (Platanus spp.)

These host plants offer the essential nutrients necessary for the larval growth and development.

Adults Feeding on Nectar

Adult Lime Hawk Moths rely on nectar as their primary source of nourishment. Their feeding habits revolve around flowers that provide an abundant supply of nectar. Some examples of flowers they commonly feed on include:

  • Honeysuckle
  • Evening primrose
  • Valerian

The Lime Hawk Moth’s long proboscis is well-adapted to reach deep into these flowers, efficiently extracting nectar. This method of feeding contributes to their role as pollinators, an essential aspect of maintaining ecosystem health.

Behavior and Mating

Nocturnal Activity

Lime Hawk Moths are nocturnal creatures, which means they are active at night. They are part of the sphinx moths family and are known for their fast and agile flight capabilities.

  • Sphinx moths can maintain high body temperatures to fly on cool nights.
  • They shiver to warm up for night-time activities.

Mating Rituals

Mating in Lime Hawk Moths involves a fascinating dance between the males and females.

  • Males detect female pheromones in the air to locate a potential mate.
  • Mating usually occurs during their nocturnal activity.

A comparison between male and female Lime Hawk Moths:

Male Female
Detects pheromones Releases pheromones
Flies fast to locate mate Waits for a mate to approach

In summary, Lime Hawk Moths showcase unique nocturnal behaviors and an interesting mating ritual. These fascinating creatures never cease to amaze with their agility and unique adaptations for survival.

Predators and Threats

The Lime Hawk Moth, like many other insects, faces various predators in its natural environment. One of the main predators of this moth are birds. Birds tend to prey on different life stages of the Lime Hawk Moth, including eggs, larvae, and adult moths1.

Hovering around flowers for nectar, Lime Hawk Moths participate in pollination2. This crucial role helps maintain a healthy ecosystem. However, habitat loss and human activities can negatively impact their population, leading to a decline in pollination services.

The conservation status of the Lime Hawk Moth is currently not a primary concern3. However, it’s essential to monitor their populations and ensure that their habitats remain protected to maintain a stable ecological balance.

Interesting Facts and Features

The Lime Hawk Moth (Mimas tiliae) is an intriguing and visually striking creature. Here are some interesting facts about these moths:

  • They belong to the family Sphingidae, which includes other hawk moth species.
  • Lime Hawk Moths are native to Europe and parts of Asia, including Yorkshire in the UK.

The appearance of Lime Hawk Moths is quite unique, with some features including:

  • Their caterpillars have a distinctive blue horn at the rear end.
  • Adult moths possess long, pointed forewings with attractive patterns.
  • They have bright green patches and yellow stripes on their wings, making them easily recognizable.

Carl Linnaeus, the famous naturalist, formally described Lime Hawk Moths in his 1758 work, Systema Naturae. As for their behavior and other characteristics:

  • Lime Hawk Moth caterpillars feed primarily on lime tree leaves but can also consume other tree species leaves.
  • Adult moths are nocturnal and are often drawn to artificial light sources.

When comparing Lime Hawk Moths to other butterflies and moths, some differences and similarities become apparent:

Feature Lime Hawk Moth Other Butterflies & Moths
Size Medium to large Varies from small to very large
Wings Long, pointed forewings Varies, often with rounded or irregular edges
Horn Blue horn on caterpillar Not present in most caterpillars

In summary, Lime Hawk Moths are unique, colorful creatures with fascinating features and behaviors.

Letter 1 – Lime Hawkmoth in Pennsylvania: Exotic Introduction or Hoax???

 

what kind of moth is this please

We had this moth at work 2 days ago sitting on the concrete most of the day and then hanging on the building for most of the night, then it was gone.

Lime Hawk Moth
Lime Hawkmoth

Dear Curious,
This sure looks like a Lime Hawkmoth, Mimas tiliae, to us. The problem with this identification is that the Lime Hawkmoth is a European species and this sighting could indicate an accidental introduction. We are copying Bill Oehlke who does comprehensive species data on the family Sphingidae, as well as the United States Department of Agriculture new pest advisory group at npag@aphis.usda.gov because the introduction of a new species to an area outside of its typical range can have significant environmental consequences and it should be treated seriously. The ease with which new species can be introduced by humans to distant locations can have dire impacts on local indigenous populations. Thanks for your cooperation in this potentially seriously matter.

Confirmation of Identification
Sat, Jul 4, 2009 at 4:52 AM
Daniel,
I agree that your id of the western PA moth is M. tiliae, and that it does not belong there.
Bill Oehlke

Ed. Note:
Now that Bill Oehlke, and expert in Sphingidae, has established that this is in fact a Lime Hawkmoth, there are several additional questions raised. First there is the possibility that this is a hoax. Though we like to believe that our readership is ethical, the possibility always exists that someone out there has “gone rogue” and is playing a joke. Once we establish that that is not the case here, the next question is whether this is an isolated individual that somehow got introduced, or if it is part of a brood or the beginning of an actual, viable introduction. More sightings would be necessary to establish that. Since the climate of northwest Pennsylvania is not dissimilar to that of the UK, and since the food tree, Linden, is grown ornamentally in northeast Ohio, and probably also in northwest Pennsylvania, the possibility exists that a population of Lime Hawk Moths may become established and spread in North America. We hope our friends at the USDA are checking their email during the holiday weekend since we just received a request to notify them of any suspected introductions. If you see a Lime Hawkmoth in the eastern portion of North America, please contact us immediately and put the name Lime Hawkmoth in the subject line of your email. More importantly, please contact the USDA at
npag@aphis.usda.gov so the authorities will know of the sighting.

Update from Doug Yanega from the Entomology Research Museum at UC Riverside
Monday, July 13, 2009
Last Friday, while we were without a computer, Doug Yanega was kind enough to leave us a voice message regarding the Lime Hawk Moth sighting.  This is a paraphrase of the message he left:  The Lime Hawkmoth is already known from eastern canada so Pennsylvania is just the first time it has been sighted across the US border. Probably introduced carelessly or intentionally from someone has imported and was rearing Sphinx Moths from overseas.

Update from the USDA
Wednesday, August 5, 2009
Hi again Daniel,
I just wanted you to know that we are still receiving emails concerning the Lime Hawk Moth and I’m enjoying how excited people are about this.
Can you post a short note that we at USDA need an actual specimen to submit it for official identification, not just a photo (although I have been enjoying the wonderful photos)? If someone is able to catch a specimen, they can email us at npag@aphis.usda.gov for the address to send it.
That would help us so much.

UPDATE: New Pest Advisory Group – Insects new to the United States
September 15, 2009
Hi Daniel,
I am once again hoping you can do one last update to the Mimas tiliae posting on your website (the one where it was found in Pennsylvania). I have finally been able to get ahold of someone in USDA that told me the official procedure:
If you have found a specimen (dead or still alive, any life stage, must be a specimen, not photos) the first step is to take the specimen to your state’s land grant university entomology department, cooperative extension office, or the state’s department of agriculture, who will then forward it to the appropriate authorities.
Can you please add this to your website? We are getting so many photos, but no one has found a specimen and now we know what the official procedure is if some are found.
Thanks so much and keep up the good work!

UPDATE FROM APHIS: Procedure for alerting APHIS about new pests
July 8, 2010
Hi Daniel,
I think there has been some confusion  as to the correct procedure of alerting APHIS to potential invasive pests.  I know Stephanie Dubon asked you to contact her in the past, but she no longer works for the USDA.  Right now the best thing for people to do is to try and get the actual specimen and submit it to their state department of agriculture or to contact their county extension agency. They will then send the specimen on to APHIS.
Is it possible to remove Stephanie Dubon’s contact information from your website?  (See Lime Hawk Moth in PA postings).  We really appreciate the vigilance of everyone out there looking for potential invasive pests,  but unfortunately, there is very little we can do in our office.  Stephanie’s position was not filled and so there is no one to handle these kinds of emails anymore.  By far, the best thing to do, as I mentioned, is to go through the proper channels (i.e., through the state departments of agriculture and/or the county extension offices).
Thank you for your consideration.  We just don’t want people to become frustrated waiting for a response.
Sincerely,
The New Pest Advisory Group

Letter 2 – One Eyed Sphinx Caterpillar, NOT Lime Hawkmoth Caterpillar in Washington State???

 

Subject:  Green Worm?
Geographic location of the bug:  Spokane, WA
Date: 08/14/2021
Time: 02:11 PM EDT
Your letter to the bugman:  found this little guy hiding in the lower crevice underneath my sliding door to the backyard. small enough to fit under the door entirely. i couldn’t see any legs and it seems to only move by flexing its body like a worm. thicker (and greener) than a worm, however. reacted a little to simply blowing in it but it didn’t react when i tapped it with a toothpick (not the sharp sides, i don’t wanna hurt it). no bigger than my index finger in length
How you want your letter signed:  Connor S.

One Eyed Sphinx Caterpillar

Dear Connor,
This is not a Worm.  It is a Caterpillar, more specifically a Hornworm, a caterpillar of a Sphinx Moth or Hawkmoth in the family Sphingidae.  Now comes the interesting part.  It sure looks like the caterpillar of a Lime Hawkmoth,
Mimas tiliae, but that is a European species that is pictured on Wildlife Insight.  12 years ago we posted a sighting of a Lime Hawkmoth in Pennsylvania and through that posting we learned that Lime Hawkmoths have already been reported in eastern Canada.  Doug Yanega, an entomologist at UC Riverside informed us:  “The Lime Hawkmoth is already known from eastern canada so Pennsylvania is just the first time it has been sighted across the US border. Probably introduced carelessly or intentionally from someone who has imported and was rearing Sphinx Moths from overseas.”  According to iNaturalist:  ” the lime hawk-moth, is a moth of the family Sphingidae. It is found throughout the Palearctic region and the Near East, and has also been identified in eastern Canada and in northern Spain (Europe).”  Twelve years have passed since that posting and it is entirely possible that the Lime Hawkmoth has either expanded its North American range across the continent or that it hitched across the country with tourists.  We might be wrong in our identification.  Perhaps Dr. Bostjan Dvorak or another specialist in the family Sphingidae will either confirm or correct our tentative identification.  If we are correct, this might be a first sighting in Washington as we are unable to locate any information on its presence there.

Update:  August 22, 2021
Thanks to a comment from Bostjan Dvorak, we have been informed that this is a One Eyed Sphinx Caterpillar, not a Lime Hawkmoth Caterpillar.

Letter 3 – Mating Lime Hawkmoths from Switzerland

 

Moth ID
Hi guys, My daughter Rosie and son Sam saw these moths on our door today…initially we thought they were leaves. We have tried to find a similar image on your site, and although it looks a little like a Pandora Sphinx moth we are not sure. This photo is from Duillier in Switzerland. We hope you can help with the ID. Thanks
Duncan, Switzerland

Hi Duncan,
The Pandora Sphinx does not range into Europe. These mating Sphinxes are Mimas tiliae commonly called Lime Hawk-moths. More information and images can be found on Moths and Butterflies of Europe and North Africa and the UK Moths page. Lime refers to a favored larval food plant, the Linden Tree which is commonly called a Lime Tree.

Hello Bugman,
Can you help me identify this moth which I found in my garden, I live in the UK.
Thanks
Simon

Hi Simon,
A little web research and we located your lovely Sphinx Moth, the Lime Hawk Moth. Lime is probably a reference to the color since the food plants are listed as “Tilia ,Prunus ,Betula ,B. verrucosa ,Alnus glutinosa ,A. incana ,Ulmus glabra” on this site with nice images. We located an additional site with much information.

Update (04/11/2006) Anita and the Sphinx!!!
lime sphinx additional note, and an image for fun! Dear Bugman
What a gift you are to us all, and to bugs and the buggable everywhere! I have a quick comment to add to your ID on Jan 03 of this year of a Lime Sphinx seen by a UK resident. Actually, the “lime” in the name IS a reference to the food plant: Tilia cordata, what we in US call Little-leaf Linden, is native to the UK, where it is a Little Leaf Lime. All the Lindens are called “Limes” on the other side of the pond, I have no idea why since no relation to the citrus fruit that I can figure out… may be an interesting story behind that! And for fun, here is me (on a bad hair day!) on my father’s front deck in Cecil County, Maryland with a sphinx moth, prob. Eumorpha pandorus, freshly emerged with nice color tho you can’t see much detail in this shot…
Best,
Anita

Hi Tom,
We believe this is the second time we have received a photo of the Lime Hawkmoth, Mimas tiliae.  The common name is derived from the food tree, the Linden, which is called the Lime Tree in England.  According to UK Moths, According to that website it is:  “A reasonably common species in the southern half of Britain, it was most frequent in the London area, where there are still extensive tree-lined avenues. In recent years its distribution has spread northwards and is now regularly found well into North Yorkshire and beyond. ”  We believe the range expansion is due to global warming.

In recent years its distribution has spread northwards and is now regularly found well into North Yorkshire and beyond. ”  The larvae, which are known as Hornworms, feed on lime, alder, birch and elm tree leaves.  We do not believe you should have put it in a jar and kept it.  Though we are not opposed to keeping insects in jars long enough to observe them, we believe they are best when left in the wild.  We have had other members of the Sphinx or Hawk Moth family Sphingidae referred to as stealth bombers because of their appearance.

Hi Alan,
This is a Lime Hawkmoth, Mimas tiliae.  According to UKMoths, it is a common species in the southern half of Britain.  We recently had a sighting in Pennsylvania, and there is documentation that the species has been sighted in Canada as well.  This probably represents an accidental introduction or possibly an intentional release from captivity raised specimens.  When we asked our readership to notify us of any additional North American sightings, we began to receive letters with photos of a similar appearing species  without the scalloped wing edges, the Pandora Sphinx, Eumorpha pandorus, which were mistaken for the Lime Hawkmoth.

Hi Joaquim,
You encountered a Lime Hawkmoth, Mimas tiliae, a species that has an extensive profile on the Sphingidae of the Western Palaearctic website which states:  “On the Iberian Peninsula this species is recorded from northern Spain and northern Portugal, with a small population in the mountains of central Spain (Pérez De-Gregorio et al., 2001). However, Rambur (1942) records a single individual from Malaga, Spain, but it’s status in this area requires confirmation.

Pandora Sphinx

Hi Joyce,
We have gotten several emails inquiring if a native Pandora Sphinx,
Eumorpha pandorus, like the one in your photo might be a nonnative Lime Hawk Moth.  The coloration of the two species is similar, but the markings are quite different.  You can read more about the Pandora Sphinx on Bill Oehlke’s excellent website, and you can see our own report of a Lime Hawkmoth in Pennsylvania from last year.  We suspect that APHIS is also getting emails from our readership, because the following request just came our way.

Lime Hawkmoth

Dear Gideon,
This is a common European moth known as the Lime Hawkmoth,
Mimas tiliae, and you may read about it on the UK Moths website.  Several years ago we reported a sighting of a Lime Hawkmoth in Pennsylvania that created quite a stir.

Wow! you responded so quickly. Thank you very much for you answer. I must say I’m a bit upset, I thought maybe it was new creature that only I had ever seen….
Pretty non the less. Thank you again!

Hi again Gideon,
There is no need to be upset.  Sometimes very common species are rare locally.  If you have never seen a Lime Hawkmoth before, it may be because its food plant did not exist in your vicinity, but that recently linden trees (called lime trees in the UK)  have been planted.  We feel it is wonderful to have common insects we have never seen before appear in our garden, provided they are not exotic introduces species that might wreak havoc on our local ecosystem.

Pandorus Sphinx

Dear Sharon,
The Lime Hawkmoth is a European species.  We did receive a report once of a Lime Hawkmoth in Pennsylvania, but your individual is a Pandorus Sphinx, a native species.

Letter 18 – Virginia Creeper Sphinx, NOT Lime Hawkmoth

 

Subject:  Lime hawk moth sighting?

Your letter to the bugman:  I found this moth resting on a trash can outside of a mall after a big storm this evening. I think it looks like a lime hawk moth though they are supposed to be just in the UK. What do you think?

Virginia Creeper Sphinx

Dear Laura,
The Lime Hawkmoth is native to Europe, and though there has been at least one North American sighting, we do not believe the species has naturalized.  This is a native Virginia Creeper Sphinx.

  1. Hello, I was on my porch today and seen a strange Moth, It was on the brick of my house it looks just like the pictures of the Lime Hawk Moth. I looked at pictures all day on line of differant moths and this is the only one that looks like it. I have a Picture of it and have keep the moth in a container to show. It looks camouflaged if you place it near a leaf or tree. Quiet unique indeed.

    • Hi Teena,
      Without seeing a photo, we are reluctant to say you have a Lime Hawk Moth. We are more inclined to believe you saw a Pandora Sphinx.

  3. We saw one of these this summer in New Philadelphia Ohio.
    Never had seen one before either. Now I wish I had taken a pic for proof!
    It was VERY large. Id guess 5″ long and 3 wide
    This bug is NO HOAX

    • Thanks for your input. The Pandora Sphinx is easy to confuse with the Lime Hawkmoth, but they have ranges that do not overlap. We do not believe the Lime Hawkmoth has been established in North America.

  4. Hi, there. I’m Tom with the Chester Co., PA Master Gardener program. We received an email with attached photo suggesting that this is a Lime Hawkmoth. It was captured here in Chester Co.

    To what email address should I send this photo in order to get a positive identification and record the presence of the moth to those interested?

  7. Saw and identified and photographed a Lime Hark moth in Mamaroneck, N.Y. which is in lower Westchester County. It seems that they have been moving north from P.A.

    This morning I found this beautiful moth. I of course seen it before when I was younger. I live in a very small town between Leesport Pa and Hamburg Pa. I was very interested in knowing what this was exactly and I am glad to have found this site and just wanted to let anyone know that yes they are in Berks County.

  10. Found this month on Couer D Alene Lake in Idaho on August 8th, 2015. It was sitting on wood railing all day and was gone by morning. Willing to send the pictures taken, if desired.

  11. The huge moth that hung on our screen door yesterday for a few hours was exactly like the one the man saw at the gas station. The amazing thing was that he was so naturally cammo
    colored. I took pics on my cell phone but have no idea of how to transfer it to the computer! His head looked like the British airplane looked head-on. Looking down it looked like he had horns on the back of his wings. Never saw anything like it.

  14. I found one just yesterday in Washington too! I was sitting under a willow tree when I heard a plop and saw it on the ground. Now I wish I took a better picture of it…

  15. Dear Bugman, dear Connor, dear Colleen, dear Sprig,

    Thank You very much for sharing this fascinating observation and all the information about similar findings, on this great site! – Whatsthatbug has essentially contributed and greatly contributes to the knowledge about autochthonous and introduced insect species.
    The Lime Hawkmoth (Mimas tiliae) has indeed been reported from several places of the northern New World as an introduced species in the last decennies, mainly from a few cities in USA and Canada; as many imported organisms, it is most likely to be found in rather urban biotopes – which can also be assumed for its homeland, where it preferably follows avenues planted with lime trees within urban centres (as a synanthropic species), a tendency observed in the last centuries in European cities (eg. Berlin) – besides its natural occurrence in “undisturbed” landscapes.
    The caterpillar on the photo shows quite some similarity with that of the Lime Hawkmoth indeed (the water green ground color, the lateral stripes and the bluish horn); however, in the genus Mimas, the rear end of the caterpillar is marked by a characteristic group of prominent colorful tubercles (as on my added photo of a larva found on Potsdamer Platz in Berlin some years ago), which are missing in this individual (smooth anal part); additionally, this caterpillar’s white pattern is adorned with two straight dorso-lateral lines – completely missing in Mimas as well, but typically occurring in caterpillars of the Nearctic branch of the genus Smerinthus – indicating that the caterpillar in question belongs to that genus; as the palaearctic species Smerinthus ocellata (European One-Eyed Sphinx) lacks those lines, and these are less intensive in the eastern nearctic species, the photo shows an individual of Smerinthus ophthalmica, the Western One-Eyed Sphinx (on its pupating march, with the colors already changed). This also correlates with the information about records on willow trees (Salix) in Washington. – Pupating Mimas tiliae larvae are of a rather greyish (ventrally rosy) base color, much smaller (contracted) and strongly rounded – and very difficult to see on paved (asphalted) ground…

    Thus, the bluish-green caterpillar on the photo is of the Western One-Eyed Sphinx, Smerinthus ophthalmica. It is part of the rich natural fauna of Your region – together with other species from 4 authochthone genera of the Smerinthinae tribe – Smerinthus, Paonias, Amorpha and Pachysphinx – from which the last three are only represented in the New World, whereas Mimas was originally only represented in the Old World…

    Best regards over the sea,
    Bostjan

  21. I just found one today, 9/23/22, Longbranch, WA. In my back yard trying to crawl up one of my tall evergreens. I wish I took photos, but my cat was trying to play with it so I had to move it to another location.
