How to Attract Luna Moths: A Simple Guide for Enthusiasts

Luna moths are stunning creatures, known for their large size and unique, seafoam green to yellow color. Attracting these beautiful insects to your garden can be a rewarding experience, as they contribute to the overall beauty and ecosystem of your outdoor space.

In order to attract luna moths to your garden, it’s essential to create the right environment for these nocturnal insects. By providing a range of host plants for the moth caterpillars and ensuring proper conditions for mating, you can increase the chances of having these mesmerizing visitors grace your garden.

Understanding Luna Moths

Luna Moth Life Cycle

The Luna Moth (Actias luna) is a beautiful large moth found in North America, particularly in Canada and Saskatchewan. Its life cycle comprises four stages:

  1. Eggs: Female moths lay eggs on host plants.
  2. Larvae: Bright green caterpillars hatch and feed on leaves.
  3. Pupae: After molting, the caterpillars form cocoons inside which they pupate.
  4. Adults: Adult moths emerge and mate, living only for a few days.

The number of generations varies, with one generation in the north, two in the Ohio Valley, and three in the south.

Identifying Male and Female Luna Moths

Male Luna Moths:

  • Have larger, feathery antennae
  • Smaller than females

Female Luna Moths:

  • Have smaller, less feathery antennae
  • Larger than males

Habitat and Distribution

Luna Moths are members of the Saturniidae family and thrive in a variety of habitats ranging from forests to suburban areas. Here’s an overview of their distribution:

  • Found primarily in North America
  • Common in Canada and the United States
  • Occur across eastern North America from Saskatchewan to Nova Scotia in Canada, south to east Texas and northern Florida in the United States

To attract Luna Moths, planting host plants such as walnut, hickory, or sweet gum trees can help. Also, reducing outdoor lighting can make your area more appealing to these nocturnal moths.

Attracting Luna Moths

Creating the Ideal Habitat

To attract luna moths, you need to create a habitat that supports their needs. Luna moths mate and lay eggs, which hatch into caterpillars in about 10 days1. The caterpillars then feed on leaves, grow, and molt1.

To support the moths’ lifecycle:

  • Provide a variety of host plants for caterpillars to feed on
  • Plant flowering plants that adult moths can use as a source of nectar

Host Plant Options2

Common Name Benefits
Birch provides leaves for caterpillars
Walnut nourishes caterpillars with leaves
Sweetgum supports caterpillars’ growth
Hickory suitable for feeding caterpillars
Beech provide leaves for caterpillars

Plants for Attracting Luna Moths

To attract adult luna moths, planting specific flowering plants provide a food source for moths with a proboscis3. Offer a variety of options to increase the chances of moths visiting your garden:

  • Lilac – fragrant and appealing to moths
  • Fuchsia – provides nectar that adult moths prefer
  • Phlox – flowers at night, making it a good attraction for nocturnal moths

Dangers and Survival

Protecting Luna Moths from Predators

Luna moths are large green moths with discal eyespots on their wings and long tails on their hind wings ^. The tailed wings help distract nocturnal predators such as bats, letting the moth escape. Moths use their unique features to camouflage in their surroundings; hence, it’s essential to provide ideal habitat conditions to support their survival:

  • Natural foliage
  • Dimly lit areas
  • Safety from pesticides

Conservation and Threats

Luna moth populations face threats due to habitat destruction, pollution, and pesticides. Human activities have resulted in the loss of essential host plants and natural environments, reducing their breeding and feeding grounds. To conserve the species, conscious efforts should be made to:

  • Plant native host trees like sweet gum and hickories
  • Reduce pollution and light disturbance in their habitat
  • Minimize pesticide usage, especially on host plants

Importance to the Ecosystem

Luna moths play a vital role in their ecosystem, serving as a food source for predators and contributing to the pollination process. Their unique features also make them excellent bioindicators for assessing the ecosystem’s health. However, their exceptional beauty also makes them susceptible to collection by enthusiasts.

Comparison of Luna Moths and other insects

Features Luna Moths Other Insects
Eyespots Present on wings Varies
Long tails On hind wings Rarely found
Nocturnal lifestyle Yes Varies
Role in the ecosystem Pollination and food source Varies (pollination, pest control, etc.)

Preserving luna moths is essential for supporting biodiversity and maintaining a healthy ecosystem. By understanding their dangers and ways to ensure their survival, we can contribute to their conservation and promote a balanced environment for all species.

How to Photograph Luna Moths

Luna moths, part of the Saturniidae family, are great subjects for photography due to their beauty. They have a wingspan of 4-5 inches and display vibrant green coloration; they can be found in forested areas with plenty of alder, red maple, white oak, wild cherry, and hickories.

To photograph Luna moths:

  • Be prepared for their active hours, typically at night since they’re nocturnal insects.
  • Attract moths by setting up a white sheet and illuminating it with a porch light or other artificial lights.
  • Use a tripod and a macro lens to capture stunning close-ups of their unique features like antenna, eyespots, and those impressive, papery wings.

Be mindful not to disturb any Luna moth caterpillars in the area while you’re photographing the adult moths.

Setting Up a Moth Trap

Finding Luna moths can be a bit tricky because of habitat loss, but you can increase your chances by creating a moth garden or setting up a moth trap in your backyard. To set up a moth trap:

  1. Choose an area with plenty of their favorite food plants—they particularly love sumac, pecan, and persimmon.
  2. Get a light trap—this can be a commercially available moth trap or a DIY setup using a bright light and a white sheet.
  3. Secure the trap—if you decide to use a sheet as the base, hang it on a rope between two trees or poles. This makes it easier for moths to land and for you to observe them.

Pros:

  • Easy to set up, even as a DIY project
  • Can attract a variety of moths, not just Luna moths
  • Not harmful to moths or other insects

Cons:

  • Might not work well without the right host plants nearby or in heavily urbanized areas
  • Can attract more common, less vibrant moths like sphinx moths, cecropia moths, and silk moths
Species Wingspan Active Hours Distinct Features
Luna Moth 4-5 inches Night Green wings, eyespots, delicate antennae
Hummingbird Moth 1.5-2 inches Day and Night Resembles a hummingbird, clear wings
Cecropia Moth 6-7 inches Night Huge, with reddish-brown wings and crescent-shaped white spots

Remember that Luna moths are not pests, so enjoy their presence and encourage others, especially children, to appreciate these fascinating creatures. By doing so, you’re contributing to the conservation of the Luna moth population and the incredible biodiversity of Florida and the broader U.S.

Pre-Pupal Luna Moth Caterpillar

Hi Eric,
Many caterpillars change from green to orange, brown or even pink just prior to pupation.  This is a Pre-Pupal Luna Moth Caterpillar.  Here is a similar photo from BugGuide.  In the spring it will emerge into an adult Luna Moth, a beautiful pale green moth with long tails.

I’m still not sure what I was seeing here but it looks to me like a Luna moth that didn’t enclose completely. It was crawling but obviously couldn’t fly. It kept falling over weeds and flipping onto It’s back so I put it on my oak tree and it energetically crawled far up the trunk.
How you want your letter signed:  Elizabeth C.

Newly Eclosed Male Luna Moth

Dear Elizabeth,
This is a newly eclosed male Luna Moth, but we do not believe it is deformed.  Metamorphosis is a process that takes time.  After the adult Luna Moth emerges from the cocoon, it might take several hours for the wings to expand fully and harden.  We suspect your individual eventually flew away to mate.  Because of your kindness, you may have helped this guy survive, so we are tagging your submission with the Bug Humanitarian Award.

My apologies. I inserted the photo instead of attaching it. Hope it finds you this time. Thanx again,
R.G. Marion

Ed. Note: R.G. sent us a very nice letter and no image was attached. We requested that she resend the letter and attach the image as we really wanted to post the mating Luna Moth photo she described. She resent the image, but not with the original letter which has vanished into the black hole of our mailbox system. We are now posting her wonderful photo and are awaiting her to resend her great letter. Sadly, it is nearly impossible, with the the mail volume we receive, to put things together piecemeal. In most cases, we would give up and not make additional requests, but the nature of this particular image warrents the time, frustration, and multiple posting requirements that the piecemeal sending necessitates. Sadly, it now limits the number of letters that will get a response today.

As per your request ~ don’t mean to waste your time!
Hello Bugman,
This photo is a couple of years old, but I still find it intriguing. Not only would it make a nice addition to your “BUG LOVE” page, but I have a nagging question about the photo itself: It looks as if there’s more than one connection between the two moths. Could you tell me if there is actually something, visible, passing between the them? There appears to be… just my imagination? These beauties were suspended over the entrance to my garage (with spider passing by) in Cosby, TN ~ The Great Smoky Mountains. With thanx for your time,
R.G. Marion

Thought you might enjoy these pictures of a pair of luna moths that spent Saturday afternoon snogging on our house. Weirdly, I had just been looking at the many beautiful luna moth pictures on your site last week, and wishing I could see one in person. Someone must have been listening. Great site btw.

After all these years running this website, we are thrilled to finally have photos of North America’s lovliest insects mating.

Letter 6 – Mating Luna Moths

 

Luna Moths Mating
Hello! I was just scrolling the Luna Moth page on your website and saw that you have a couple of pictures of Luna Moths mating. Today we have a pair on our fence and they have been there all day. We saw one on the fence last night by himself and today he was joined by his mate. I have been outside several times to take pictures and thought you might enjoy a few to post on your website if you’d like. I was saddened to read that the Lunas only live a few days. No wonder these two are spending so much time together! Enjoy!

Since I sent these, we have also located the chrysalis/cocoon of what we assume to be the female who was originally on the fence the day beflor, as the females apparently do not fly until after mating.

Letter 11 – NOT Luna Moth Caterpillar but Polyphemus Moth Caterpillar

 

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

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

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

We stand corrected.

Luna Moth in Canada

Good morning Fa[s]cinated in Canada,
Thanks so much for reporting your Canadian sighting of a Luna Moth.  Each year, we enjoy tracking the appearances of Luna Moths beginning with the Southernmost reaches of the range in Texas and Florida, generally in February.  As spring weather conditions move north, the Luna Moth sightings come in subsequent months until they culminate with sightings in Maine and Canada in late May and early June.  In the south, a second generation often flies in the late summer or early autumn with the second generation passing the winter as a pupa.  The individuals from the north also pass the winter as a pupa after the caterpillar forms a cocoon using a leaf that usually falls to the ground where it is covered in fallen leaves and eventually snow.

Hi Chris,
Your colorful subject line caught our attention.  This is a male Luna Moth, and it is most likely a second generation that eclosed from a caterpillar that was produced by Luna Moths that emerged from their cocoons earlier this past spring.  Luna Moths do not feed as adults, and they only survive a few days, long enough to mate and lay eggs for a future generation. 

Letter 15 – Male Luna Moth: sidewalk rescue

 

Subject: Luna Moth
Location: 26 State St., Montpelier VT
June 8, 2014 5:26 am
I live in downtown Montpelier, VT. Returning from walking the dog at about 8 AM today (6/8/14), I found this guy resting on the sidewalk right in front of my door. At first I thought it was a leaf, but when I realized it was a moth I figured I had to move it before someone stepped on it (or my dog tried to eat it). After nudging it a bit, it flapped around for a few feet, but seemed to have trouble flying. It ended up in the well of tree planted in the sidewalk. I thought it might be injured. I gently nudged it a bit more, and it managed to get enough air to clumsily climb into the sky, and then it flapped off above the surrounding buildings. It was quite a sight!

Letter 16 – Pre-Pupal Luna Moth Caterpillar

 

Subject: Orange Grub in woodsy area
Location: Woods in Adirondack Mtns. near Saranac Lake, NY
September 1, 2014 9:50 am
This grub was found while camping in the woods near a pond in the Adirondacks in northern New York a few days ago. It’s color was what stood out the most. Its legs had super suction capabilities and it crawled around the ground at a very fast paced. I almost think it’s a Scarab Beetle Grub but the color doesn’t match most. We watched the grub crawl across the ground, up a dead tree stump and come down the other side. It found it’s way to an area of the ground covered in pine needles, dead leaves, twigs. It looked like it was going into some sleep mode where it began to coil into itself, covering itself with the surroundings on the ground. As time went on it looked as if it cacooned itself in a hard sticky shell covered by the leaves, twigs, and pine needles. Left before seeing what happened after. Thought it was a very interesting little bug.

Male Luna Moth
Male Luna Moth

Like other Giant Silkmoths, Luna Moths do not feed as adults, meaning they must survive off of energy in the form of fat stored while the caterpillar was feeding.  Flying takes tremendous energy.  The female Luna Moth lives as an adult to mate and then lay her eggs.  The male Luna Moth flies to locate a female when he senses her pheromones.  He does not fly around needlessly.  If there is no female nearby, your male Luna may be waiting until he catches the scent of a female before he flies off.  In a previous Cecropia Moth posting, we recommended relocating the female so that she might lay eggs.  There would be no purpose to relocate this male unless it is to place him nearer to a mate.  Adult Giant Silkmoths, including the Luna Moth, only live a few days, perhaps a week at most.  Sadly, if this male does not sense a female soon and fly to mate with her, he may die at your front door.  Our advice is to wait and let nature take its course.

thank you so much for responding , I did relocate him to a tree in my front yard so no stray cats in the area will eat him as a previous posting on your website had mentioned. Im so happy I found your website and was educated about these beautiful moths.

Pre-Pupal Luna Moth Caterpillar

Dear Ryan and Emily,
Distinguishing a Luna Caterpillar from a Polyphemus Caterpillar can be challenging, but we believe your caterpillar is a Luna Caterpillar.  The pink coloration is due to it being pre-pupal, and we have seen numerous images of pink pre-pupal Luna Caterpillars.  Luna Moth caterpillars, according to BugGuide, are:  “Larva lime-green with pink spots and weak subspiracular stripe on abdomen. Yellow lines cross the larva’s back near the back end of each segment (compare Polyphemus moth caterpillars, which have yellow lines crossing at spiracles). Anal proleg edged in yellow. Sparse hairs.”  Your individual is lacking the “yellow lines crossing at spiracles” that are present in Polyphemus Caterpillars.

Thank you so much Daniel.  What a tricky ID!  Much appreciated.
Update:  August 17, 2019
Bugman (Daniel)– our strangely-colored Luna caterpillar has made a cocoon by folding up some birch leaves in its fish tank terrarium.  I’m aware that it should be misted periodically so it doesn’t dry out…how often is that necessary?  How many days can you skip the misting, without it drying out to death?
Thank you again so much for the ID of this creature.  –Ryan
Hi again Ryan,
We do not raise caterpillars in captivity, but the problem with a terrarium is that it is cut off from external conditions.  Outdoors, the cocoon would be exposed to rain and other precipitation.  Another problem with raising caterpillars indoors is the stable temperature that occurs in modern homes, and this can effect emergence time which presents problems when adults emerge at a time of year that prevents release back into the wild (like an indoor emergence in the dead of winter).  The important consideration is not how often you mist, but when you mist.  If the captive conditions get too dry, the pupa might desiccate.  Trying to duplicate outdoor conditions in a protected environment is a goal.  Good luck.

  1. I wanted to post that had a luna moth under my deck today.I live in Lincoln N.B which is just outside of Fredericton N.B. I thought it was a big leaf at first. I don’t know how long it was there but when I checked this evening, it was gone. I have never seen one before.

  2. June 25/11 We saw a luna moth north of Parry Sound in the Franklin Island area washed up on the beach covered in sand. We cleaned it off and put it in a safe place to recover, however the wings were damaged, so it may not have survived.

  3. Today, April 27, 2014, at about 8 AM, on the Eastern Shore of MD., I observed a pair of these moths, side by side, on a support post for one of my trees. They were about 3′ off the ground I photographed them as best I could.

    Perhaps they were mating??? Are they rare in my area? Any other information??

    Regards, Rich

    • They are found in your area. Though they are not considered rare, population numbers may vary from location to location. More information is available on BugGuide.

    • When a Luna Moth Caterpillar changes from green to orange in color, it is nearing pupation. If you provide favorable conditions, it should pupate indoors, but we would urge you to try to duplicate outdoor temperatures and conditions so it emerges on schedule and can be permitted to mate and reproduce.

  6. Dear Sheila,
    I love your picture of the mating Luna Moths.
    I would like your permission to make a painting using the photo as inspiration- I don’t know how it will turn out!
    Best wishes, Jilly.

  8. Luna Moth found clinging to the door of my shed in Pocologan, NB. It may be nearing the end of it’s life cycle, as it is not inclined to move, no matter how often I approach it.
