The Luna Moth, a fascinating and ethereal creature, has captivated observers with its vibrant colors and unique physical features. Boasting an impressive wingspan of 3-4.5 inches, these moths flaunt a magnificent sea-foam green to yellow hue, making them a sight to behold in North America. Derived from the name of the Roman moon goddess, Luna, these moths are also known as the American Moon Moth and can be commonly found throughout regions such as South Carolina source.
Not only are Luna Moths striking in appearance, but they also exhibit intriguing behaviors that contribute to their symbolism and meaning. For example, the tails on their hindwings serve a unique purpose – they help disrupt the sonar of hunting bats, increasing their chances of survival source. As we delve deeper into the world of Luna Moths, you’ll uncover a wealth of fascinating facts that will shed light on the meaning and significance of these remarkable creatures.
Luna Moth Overview
Appearance and Physical Features
- Wingspan: Luna moths have an impressive wingspan of 3-4.5 inches1.
- Color: Their sea-foam green to yellow color makes them easily recognizable1.
- Antennae: Luna moths possess feathery antennae, particularly in males2.
- Tail: A unique feature of these moths is their long tails on the hindwings2.
Habitat and Range
Luna moths, or Actias luna, are nocturnal insects found mainly in the eastern region of North America3. Their geographic range spans from Canada to eastern Texas and Florida, and as far north as Nova Scotia and Maine3. They commonly inhabit forested areas, thriving in both deciduous and mixed forests4.
Life Cycle of a Luna Moth
Eggs and Larvae
Luna moths begin their life cycle as eggs, which are laid on the leaves of host trees. Female luna moths typically lay around 100-300 eggs in small batches on the underside of leaves. These eggs hatch into tiny larvae, which start to feed on the leaves they were laid on.
As the larvae grow, they turn into bright green caterpillars. Luna moth caterpillars have:
- Convex segments with narrow yellow bands
- Ability to make clicking noises and vomit to deter predators
During this stage, the caterpillars eat a lot to support their rapid growth. They eventually become large, plump caterpillars before moving on to the next stage of their life cycle.
Cocoon and Pupa
When the caterpillar is ready for metamorphosis, it spins a silk cocoon around itself. This cocoon is where the pupa will form and the transformation into an adult luna moth will take place. This pupal stage lasts for about 2-3 weeks in spring and summer.
Adult Luna Moth
Once the metamorphosis is complete, an adult luna moth emerges from the cocoon. Some key features of an adult luna moth include:
- Pale or lime green color
- 3-4.5-inch wingspan
- Long tails and eyespots on all wings
- Feathery antennae, especially on males
At this stage, adult luna moths have a very short lifespan, usually only surviving for about a week. Their main purpose is to mate and lay eggs to continue the species.
|Caterpillar Stage||Adult Luna Moth|
|Purpose||Growth and preparing for metamorphosis||Mating and laying eggs to continue the species|
|Features||Bright green, clicking noises, and vomiting||Pale green, large wingspan, long tails, eyespots|
The life cycle of a luna moth represents new beginnings as it goes through these fascinating transformations from egg to adult.
Survival Strategies and Predators
Eyespots and Tails
Luna moths have fascinating strategies to protect themselves from predators. One method involves the presence of eyespots on all four wings, which confuses predators and misdirects an attack to a less vulnerable part of their body1. Their long tails also serve an essential function – as predators often target them instead of the moth’s head, increasing their chances of survival1.
Another ingenious survival strategy is avoiding predation by bats. Luna moths have tails on their hindwings that disrupt the echolocation signals bats rely on for hunting3. This allows luna moths to remain under the radar and increase their longevity.
Luna moth caterpillars also employ unique defense mechanisms, such as producing a clicking noise and ejecting a distasteful fluid3. These techniques deter predators and significantly contribute to their survival in the wild.
Comparison Table: Luna Moth Defense Strategies
|Eyespots||Confuse predators by appearing like a more significant threat1||Redirects attacks to less vulnerable areas|
|Tails||Distract predators from the moth’s head1||Often targeted, increasing survival chances|
|Echolocation Avoidance||Disrupt sonars of hunting bats, making moths less detectable3||Elude bat predation|
|Caterpillar defense mechanisms||Produce clicking noises and distasteful fluid3||Deter predators|
Symbolism and Spiritual Meanings
Transformation and Renewal
The luna moth symbolizes transformation and renewal due to its life cycle consisting of drastic changes. As a caterpillar, it represents the beginning of a journey and then emerges as a beautiful moth, signifying personal transformation and growth.
- Caterpillar stage represents beginnings
- Moth stage represents transformation
The luna moth acts as a reminder to embrace change and trust the process of personal growth.
Intuition and Lunar Energy
Luna moths are associated with intuition and lunar energy due to their nocturnal nature and connection to the moon. They symbolize trusting your gut and following your own path.
- Nocturnal, connected to the moon
- Represents intuition and trust
Luna moths also symbolize good luck and embracing the unknown, as they are creatures of the night, often appearing during times of change.
Divine Feminine and Duality
The luna moth represents the divine feminine and duality, embodying both the grace and power of the feminine spirit. Their lunar connection ties them to the nurturing and intuitive energies of the moon.
- Associated with grace and power
- Connected to nurturing and intuitive energies
As a totem animal, the luna moth encourages embracing the dual aspects of one’s nature, such as strength and vulnerability, and seeking balance in life.
|Transformation and Renewal||Intuition and Lunar Energy||Divine Feminine and Duality|
|– Personal growth||– Trusting intuition||– Balance in life|
|– Embracing change||– Lunar energy||– Strength and vulnerability|
|– Beginning of a journey||– Good luck||– Grace and power|
Threats and Conservation Status
Endangered Species and Pollution
- Luna moths (Actias luna) are not currently considered an endangered species.
- Pollution can threaten their habitats and food sources.
Pesticides and Other Threats
- Pesticides can harm luna moth caterpillars, which graze on tree vegetation.
- Caterpillars deter predators with clicking noises and vomiting.

Fun Facts and Additional Information
Photographing Luna Moths
Luna moths, also known as moon moths or American moon moths, are a stunning subject for photography due to their vibrant green color and distinct eye-like markings on their wings. Here are some quick tips for capturing their beauty in a photo:
- Take photos at night, as they are nocturnal insects
- Use a gentle flash to illuminate their unique green hue
- Choose an angle that showcases the intricate details, like their long tails and eye-like markings
- Be patient, as they only live as adults for about a week, making these encounters rare and special
Luna Moths and the Butterfly Connection
Luna moths are part of the silk moth family, separate from butterflies. However, they share some intriguing connections:
Luna Moths vs. Butterflies:
|Wings||Large, broad, green, & eye-like markings||Mostly smaller, more colorful patterns|
|Life Cycle||Complete metamorphosis (egg, larva, pupa, adult)||Complete metamorphosis (egg, larva, pupa, adult)|
- Both undergo complete metamorphosis
- Adults have wings covered in tiny scales
- Both are pollinators
- Bright colors and patterns serve as a defense mechanism against predators
While luna moths and butterflies evolve alongside each other, sharing features and ecological roles, they remain distinct in many ways. No matter if you’re photographing them or observing them in nature, these enchanting creatures have much to offer.
Over the years, our website, whatsthatbug.com has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.
Letter 1 – Canadian Luna Moth
i found your site while researching this wonderful wing insect i found attached to the door….I recently moved from the Missouri to Nova Scotia Canada. I am amazed every day with the beautiful, birds, insects, and plant life. i first saw The Luna Moth a week or 2 ago during the full moon. I squeeked like a lil girl at first when i saw it due to the size my mother in law was soooo happy to see it i had to find out more about the luna moth. We have now had 3 here in the last week . I took a couple pics of this beautiful female i believe thanks for all the great info listed on your site
Hi Doffy and Jill,
Your letter is so genuine it touches us. Thanks for adding to our archive as well.
Letter 2 – What is the best season for Luna Moths in Pittsburgh???
Subject: Luna Moths
October 5, 2016 1:50 pm
I’d like to plan an outing this year where we would have a higher likelihood of seeing a Luna Moth. What is the season for the Luna Moth in Pittsburgh, PA?
Ed. Note: Once we learned the lovely, originally submitted image was not taken by David, it was removed and replaced with an image from our archives.
Your Luna Moth image is positively lovely. When did you take it?
We will request our readers who live in Western Pennsylvania and Eastern Ohio within 50 miles of Pittsburgh to write in with any personal Luna Moth sightings. According to BugGuide, Pennsylvania sightings are between April and September, but we are not certain those sightings distinguish between caterpillars and imagos. According to Ohio BugGuide data, May through August, skipping to October are months with sightings. In our own archives, we would stick to images of mating pairs as that seems like peak season, in our minds. This Swarthmore, Pennsylvania sighting is from August 5, 2016. This Pulaski Township sighting is from June 1, 2014. This reintroduction program from Chagrin Falls, Ohio occurs at the end of July to the beginning of August.
I did not take the photo, it was required for a submission. But I do volunteer with Venture Outdoors and we are planning some Citizen Science outings with respect to insects.
We did a wonderful Monarch banding trip last Sunday but did not see a single Monarch. We did see 2 pairs of mating Praying Mantises.
Thanks for your help in planning our Spring moth event!
Thanks for letting us know that you did NOT take the image David. Do you have permission to post the image or was it pilfered from the internet? We are very conscious of internet plagiarism and copyright infringement, and we will have to remove your submitted image and replace it with one from our own archives if you do not have permission. Our standard submission form clearly states: “By submitting an identification request and/or photo(s), you give WhatsThatBug.com permission to use your words and image(s) on their website and other WhatsThatBug.com publications. Also, you swear that you either took the photo(s) yourself or have explicit permission from the photographer or copyright holder to use the image.” We hope folks from the Pittsburgh area write in with any information they might have about sightings from previous years. You might want to check back nearer to your trip planning time to see if there are any comments submitted to this posting.
It’s not my image, and I did not intend to post, just wanted to ask a question
Thanks David. We will remove it and replace it with an image from our own archives.
I’m so happy to discover your website and I will be happy to post REAL pictures in the future. For example I lead a butterfly event every July that participates in the NABA count.
We look forward to future submissions from you David.
Letter 3 – Cocoon: Luna Moth or Polyphemus Moth
Subject: Identifying Large Cocoon
Location: Western Pennsylvania, USA
September 4, 2016 3:59 pm
Hi, My kids & I found this cocoon & we’ve never seen anything like it , it was laying on the ground underneath a large oak tree, looked like a leaf or leaves that are kinda stringy/fuzzy almost rope like, & tightly wrapped/rolled up into a very hard &solid cocoon that’s about 3 & 1/2inches long, & 2inches in diameter, &has 2small holes, each about as big as a pencil, & there appears to be something in it, but I’m not sure what it is, if it’s alive, how to tell, we are always discovering creatures of every kind, occasionally have come across some rare & endangered species, even thought to possible be extinct in our area, & through out all of adventures in exploring I have never seen a cocoon this large or looking anything like this, & the only insect that I could think of even close to this size is a cicada, &tho I’m not certain it’s a cocoon, maybe an eggsack or nest of some sort, we are very interested to learn about what’s around us & what this new discovery beholds, thank you for your time, knowledge, expertise, &information on this matter
This cocoon belongs to either a Luna Moth or a Polyphemus Moth, and the two holes are not a good sign because they may mean the cocoon was parasitized. Gently shaking the cocoon should produce a sound like a heavy marble or something is inside. If it sounds more like a rustle, it probably means that a wasp or fly has parasitized the cocoon.
Letter 4 – artfully shot Luna Moth
Have Never Seen Anything Like This
Attached is a photo I took at my office on May 23, 2006 in Virginia, Minnesota – from looking at your site I have to assume it is a Luna Moth – I have never seen anything like this before and I have been around for awhile – it’s hard to believe something this pretty can be classified as a moth – most of the moths I see around here are not pretty at all! It blends so nicely with the color of the wood it landed on.
Your photo almost looks art directed. The background color is perfect for the lovely Luna Moth.
Letter 5 – Backlit Luna Moth from North Carolina
luna moth pic
love your website! I thought I would send you a picture of our lovely luna moth we found this morning hanging on the edge of a hosta leaf. The color of the moth and hosta matched so perfectly we wondered if it was more than coincidence that he chose to land there?
David & Patricia
Hi David and Patricia,
I must say I feel a twinge of jealousy whenever we receive a new photo of a Luna Moth, and yours was the second today. The backlighting in your photo really reveals the delicate beauty of America’s most beautiful moth. Growing up in Ohio, I never ever saw a living one. Now that I am in California, there is no chance unless I happen to holiday back east when they are flying. Thank you for you kind words.
Letter 6 – damaged goods: Luna Moth
Large green moth in GA
This moth visited my back deck on a warm rainy night this June 11, 2005. One pair if "eyes" on the wings is clearly visible in the photo; there is another pair on the secondary wings, and you can just make them out through the top wings. There appears to be damage to the covered wings in the photo. Is this a type of Satellite Sphinx moth?
Your moth is a Luna Moth, perhaps the lovliest North American Moth.
Letter 7 – Bug of the Month: April 2007 – Luna Moth in Texas
Took a pic of this Luna Moth on February 27, 2007, just north of Houston, Tx
This is the first official Luna Moth photo we have received this year, and it is a gorgeous photo.
Ed. Note: (04/01/2007)
We have been receiving countless letters and images of Luna Moths from the Southern part of their range beginning in February and increasing in March. We suspect it is not too late to make the Luna Moth the Bug of the Month for April since the northern specimens will begin to emerge as springtime weather hits the north. These emergences should continue through May and June for the most northern specimens in Maine and Canada. Luna Moths overwinter in cocoons formed around leaves from the deciduous trees that they feed upon. These cocoons usually drop to the ground where they remain among the leaf litter. The warm spring sun stimulates the metamorphosis of the adult. Adults live only a few days and do not feed. They mate, lay eggs and die if they do not become a food source for birds and other predators first. The caterpillars spend the summer fattening up on leaves before pupating. There are two generations in the southern portion of the range..
Letter 8 – Cecropia Moth
Promethia or Tulip tree?
Sun, Jun 28, 2009 at 6:50 PM
Hello Wonderful Bug People.
Working at a horse farm in Uxbridge Ontario, many mornings provide Moths and Bugs that need ID. I love your site and we now have a group waiting for me to go home and identify, the beautiful and strange things we see. I have my trusty camera at the ready so I can compare with your photos. Thanks for help identifying a Giant Toe Biter, and Luna Moth.
We had this visitor last week. I was hoping it was a Promethia or a Tulip Tree, but thinking it is probably Cecropia?
Thanks for the great site, and helping us appreciate (no longer so icky) bugs.
I’ll send our Luna as well. It was huge.
I hope your camping trip was only buggy in a good way.

Your letter arrived while we were still in Northern California at a wedding, and we are trying desperately to post as many submissions as possible. Mail really piled up in our absence and it continues to arrive in droves daily. We are going through older submissions in search of a subject line we remembered because of an unusual posting of a Purplescent Longhorn we just posted, and we thought, perhaps, that the other letter might also contain an image of a Purplescent Longhorn. Needless to say, we stumbled upon some intriguing subject lines we missed previously, including yours. We were so touched by your kind letter we decided that we needed to take the time to post your letter and photo of a Cecropia Moth. The Luna Moth photo is also quite nice.
Letter 9 – Battered Luna Moth
I never saw anything like this before
August 31, 2009
I saw this bug on August 31 around 2:00 pm while I was at work. It seemed to be resting on the side of a wall next to a doorway. I thought it was a leaf at first but at a second glance I realized it wasn’t. I never saw a flying insect like this before especially around my area so I am curious as to know what it is.
Matthew S. Gremo

This is a very battered Luna Moth that is missing its elegant tails. Though the tails are quite distinctive and lovely, they are not truly necessary for flight or survival. Since Luna Moths are tasty treats for birds and bats, we suspect the life of many a Luna Moth has been spared when a predator made off with a mouthful of wing rather than a fat succulent body. It is our opinion that the wing development of a Luna Moth is a highly evolved survival tactic. Luna Moths do not feed as adults, and die within a few days of emergence from the pupa. If losing the tails on the wings allows the adult moth to survive just a few hours longer, it will have time to mate and lay eggs, securing the production of a new generation.
Letter 10 – First Luna Moth from Maine
June 10, 2010
I got this picture from my niece and I came on to see if it was a Lunar Bug but you had no information for it. So I thought I would send you the picture. This was taken in Maine.
Take care Carol
Your Lunar Bug is a Luna Moth. Each year we like to document the first Luna Moth sighting we get from Maine as an indication of what is happening with the weather. We generally get the first Luna Moth images of the year in February from Florida.
Letter from Tiffany

Luna Moth in WI
I want to thank you for your wonderful website! I have been looking at your pictures of Luna Moths for years and was SO excited when I finally saw one here in Wisconsin last week! It was the most beautiful insect I have ever seen and I knew exactly what it was, thanks to you!!
We are envious Tiffany. Despite growing up in Ohio, we have never seen a living Luna Moth in the wild, and now that we are in California, there is not much chance. Next week we will be in Ohio for a week, and we hope we are lucky enough to see a Luna Moth.
Letter 11 – Bug of the Month March 2011: Luna Moth Swarm in Texas!!!
Luna Moth – Huffman, TX
Luna Moth – Huffman, TX
Location: Huffman, TX
February 28, 2011 9:49 am
Good morning! When I arrived at our warehouse this morning, there were a few dozen of these moths on the north exterior wall. Our warehouse is located in Huffman, TX, which is on the Northeast side of the greater Houston metro area. After searching, they appear to be Luna Moths, but I have never seen them before. We have had relatively dry weather as of late, and these pictures were taken around 8:00 a.m. on Monday, February 28th. They also appear to be quite lethargic. Are they spawning now?
Signature: Thad Fehlis
We are very excited about your email for several different reasons. First, we want to congratulate you on what must be a spectacular sight. We imagine much of our readership as well as our editorial staff are quite envious that you witnessed dozens of Luna Moths at one time. Since it is time for us to select a Bug of the Month for March, we cannot think of a more fitting candidate than the Luna Moth, even though it has received the honor of being Bug of the Month once before, nearly four years ago in April 2007. Luna Moth sightings typically begin in February in the southernmost reaches of their range in Florida, and as spring progresses, sightings appear in the more northern climes, generally peaking in May for Maine and Canada. Luna Moth adults do not feed and they have a very short lifespan. Adults mate and lay eggs and quickly die, so if you have swarming Luna Moths, they must be spawning. Thanks for getting our day off to a wonderful start.
Thank you for the quick response. As I’m sending you this email, two more of them just landed on my window. Having grown up in Austin, TX, I had the good fortune of seeing the annual Monarch butterfly migration. It’s quite a sight to see thousands of Monarchs together. Here in Houston, the Natural Science Museum has a butterfly exhibit, which allows you to see the cocoon hatchery as well as an enormous walk through controlled environment where several species of butterfly and moth fly all around you.
Do you have a good source where I can find out what other “rare” species of moth are in this area? We have also seen some interesting moths in the College Station are which, at first glance, we thought were hummingbirds. Do you happen to know what these might be? They moved very quickly, and were about the same size as the Luna.
Hi again Thad,
Though our category states that the Luna Moth is a rare species, that is not entirely true. Some local populations, like yours, are apparently quite plentiful, though in other parts of their range, Luna Moths are quite rare. The other moths you describe are probably Sphinx Moths in the family Sphingidae. You can try to identify the species you saw on the Sphingidae of Texas webpage.
Letter 12 – Deformed Luna Moth lays Eggs
Location: Central FL
July 9, 2014 8:02 am
this is camped out on my patio in Central Florida. Not really sure what it is
This is a female Luna Moth and she has atrophied wings that for some reason did not develop normally. Many people consider the Luna Moth to be the most beautiful North American moth. Despite the failure of her wings to develop properly, she has laid eggs. If she mated, the eggs will hatch, but if the caterpillars are unable to locate an appropriate food supply, they will surely perish. The caterpillars of Luna Moths feed upon the leaves of “a variety of trees including white birch (Betula papyrifera), persimmon (Diospyros virginiana), sweet gum (Liquidambar styraciflua), hickories (Carya), walnuts (Juglans), pecans, and sumacs (Rhus)” according to BugGuide.
Letter 13 – First Luna Moth of 2016
Subject: Pretty Green Moth
Location: Virginia Beach
April 19, 2016 1:22 pm
Spotted this big guy hanging out in the window of the local grocery store, above some bags of mulch.
It’s wing looks damaged though 🙁
Never seen a moth that color before. Is it even a moth?
Even with damaged wings, this male Luna Moth, our first report of 2016, is a beautiful creature. We suspect an encounter with a predatory bird resulted in the wing damage. Normally we get our first Luna Moth reports of the year in late January or early February from Texas or Florida, and by May we get reports from Maine and Canada.

Happy New Year Bostjan,
Thank you for submitting your beautiful drawing. Argema mittrei is really a beautiful Giant Silkmoth. While we do not have any images on our site of that species, we do have an image of a relative from the African mainland, Argema mimosae, on our site. We also have an image of what we believe to be the Caterpillar of Argema mimosae. Perhaps you can let us know if that identification is correct. Mada Magazine has a nice article on the Madagascar Moon Moth or Comet Moth.
