Luna Moth - Actias luna

I think these are beautiful and so interesting!

I think these are beautiful and so interesting!

Luna Moths, Actias Luna

I recall the first time I saw a Luna Moth, and I was so amazed. It was such an interesting color, and had such unique markings, and the size alone was eyecatching. I was able to capture it in a picture, and I was so glad. It got me curious to learn more about the Luna moth, which is also known as the American Moon Moth.

This beautiful and exotic moth is large. It ranges from 3 to 4.5 inches and the name is technically Actias Luna (Linnaeus). Its wings are a pale green, and has delicate tail streamers. The wings are broad, and have a reddish rust color along the edges of both the fore wings and hind wings. Depending on the region, the colors can vary from more bluish green to a yellow in the background coloring. Along the fore wings in the very front you will see a darker purplish gray color. From a distance however, it is primarily a beautiful lime green, and the very distinctive "eye spots" are just fascinating to observe. This surely helps to protect from would be predators, that would rather move on than mess around with something that has eyes that appear to be that big!

In the United States, these moths are actually fairly common in the Eastern United States, and some states, like Missouri, Arkansas and others. You can sometimes see them in Southern Canada. Luna moths are large enough, that you would see the shadow of them flying by, or could darken a room if they landed on a light bulb!

The Beautiful, Green, Luna Moth

Luna Moth Larva and Life Cycle

The larva of the Luna moth are bright green (see video below) and have narrow yellow lines on them. There is a band of yellowish spiracles, and some reddish colored tubercles on each side. some have observed raised pink spots, and this can vary from region to region. The head of the caterpillar is a brownish color. When the time comes for it to spin its cocoon it will do so in areas where there is a lot of leaves on the ground, among the leaves. Its cocoon is thin and silken.

The habitat you will most often find the Luna moth is deciduous woodland in North America, although there are fewer in Canada. The foliage of trees like birch, willow and alder, walnut (or juglans nigra), persimmon (or diospyros virginiana), and sweet gum (liquidambar stryaciflua) are the food the larva feed off of. Luna Moths like broad leaved forests, including ones with hickory trees. So if you hope to attract these beauties to your area, those would be good choices to plant. The adults will be attracted to areas with these trees, so their young have the right food to eat when they "hatch" from their eggs.

The adults will emerge from their cocoons in April, usually. Their cocoon is often found in leaf litter. The eggs will be laid on hickory, walnut, and possibly a few other trees, as was covered before. When the caterpillar is ready to make its cocoon, it uses silk and leaves to do so. It emerges as a second generation adult in late July, and may even have a third generation.

As far as the second or third generation possibility, this is the case for the United States, more than it is true for the more Northern areas like in Canada. In those areas, it is usually just one generation. The more southern the area, you can move up to a third generation. Maybe that is why I got lucky and saw one in Arkansas. It was the first time I saw one in person.

Basically, for the multiple generations, they are spaced every eight to ten weeks apart, and often start in March.

The female lays 4-600 eggs on the underside of leaves. These incubate for 8-13 days.

I just love the distinctive color of the luna moth, along with its long tails. It definitely stand out among other moths, especially for North American Moths. In the Midwest states, the luna moth flies from early April, to the end of August.

Both of the sexes of the Lunar moth look very similar, though the males antennae are more "feathered" looking. 

They have their "calling time" around the midnight hour. The calling time for the luna moth (and for many moths) is when pheromones are released. The time frame for luna moths is two to three hours long. This is the time that most males are active. In the Saturniidae family, you will see the pheromone activity the most active compared to the other "families" of butterflies and moths. Once in a mating position, they can stay there for up to 20 hours.

The life span is fairly short for these moths, about two weeks or less. They overwinter in the pupal stage.

I wish you could see the one picture more close up, as it shows the luna moths feathery antennae. These moths are just amazing creatures to behold, and I felt very lucky that day in Arkansas when I saw the moth. It was just resting among the rocks as you can see in my picture.

Seeing Less and Less of the Luna Moths

In some areas where there has been a lot of spraying with pesticides, it could be very rare you see one of these beautiful Luna Moths. They are simply becoming harder and harder to find. Evidently, even in the best of conditions, the number of Luna Moths are rather small. A single planeload of pesticides can supposedly wipe out the species for decades! When I heard this, I was so sad. I understand the need for pesticides, but if this species was totally wiped out, I think I may have rather gone with the lack of pesticides. I suppose it depends on the survival of humanity, but we are not at a point where this seems to be a critical concern. So it is something worth thinking about, or possibly limiting.

Gregory on August 20, 2020:

Found 3 on my back porch a few years ago. 2 were mating the 3rd was trying to get in on the action! That seemed to be all they cared about nothing fazed them even when i moved them so my dogs wouldn't eat them. They are really beautiful to see glowing in the night. I still have pictures on my phone.

Jessie8709 on July 11, 2020:

I found a Luna moth tonight (in CT 7/11/20 10:40pm) in my driveway. It has lost a wing and can’t fly. So I brought it in my house. It’s so beautiful I can’t leave it out there to be eaten. I let it crawl up onto my finger and it’s just been sitting here for the past hour. Idk what to do, I don’t want to release it. I’m sure it’ll die. But I’m not sure how to care for it. Wish I could add photos, it’s stunning.

Amanda Benedict on July 10, 2020:

Maureen on June 21, 2020:

Found one very large one, in my house this morning!! Thought the dogs had brought in a garden ornament, but no, it was alive. Was able to grab it by the hind wings and bring outside. I flew away after about a minute or two on the deck!!

marty on June 19, 2020:

I saw one earlyyesterday morning in the Berkshires wiggling into a vertical

position face down on about 4 inch high grass so that it was the same height as the grass. Looking down at the grass you could only see its

edge. It looked just like the recently cut field grass. I thought it had left

but then it started to shake vigorously. Above another moth flew from

a nearby eave to a yound branch directly overhead

Lynn Reid on June 17, 2020:

I saw one today on a window screen, Pictou Nova Scotia. It was about 2-3 inches.

Lynne Thies on June 16, 2020:

Marie T on June 15, 2020:

At 9:00AM 6/15/2020, in Highlands NC, I saw three Luna Moths in a pile on the Window sill about 8ft from the ground. Suddenly, one was thrown off the pile. He landed on his back at my feet. He tried and tried to flip over I used a leaf to flip him and I moved away. When I came back he was getting very weak and small flies were settling on him. I used a clear dish to move him into the sun and covered him with the plate Five minutes later he was trying to fly. I removed the plate and put him on my fist and threw him into the air At first he struggled, then he caught a breeze and went off above the tree line. Amazing.

I saw two Luna Moths in separate gardens in Augusta GA in 2018

Columbia maryland on June 15, 2020:

Shannon Stoughton on June 14, 2020:

My husband and I found 2 caterpillars yesterday (6-13-20) within the first 30mins of the find they had started to cocoon. We are in Everetts, NC. We currently have then set up in a 20gal tank. I’m hoping we’re south enough that I have a 2nd gen, otherwise they’ll be cocooned for 9mons

Tiffany Seifert on June 13, 2020:

I found one floating on the water, I thought it was dead. I brought it back to the cabin and it is starting to move . I am not sure but it may be drying it’s wings. One of his front legs is either missing or hasn’t come out yet. She or he is resting here on my arm right now.

Linda Pepin on June 12, 2020:

I found one clinging to the siding of my house yesterday (June 11, 2020). This is the first time I have ever seen one. I live in Prince Edward Island, Canada.

Chris L on June 11, 2020:

5 years ago was my first experience seeing a Luna Moth. I had dozens around my house and even 3 dead I picked up and saved as you would a butterfly. The last 5 years has been filled with tragedy, trauma and much craziness and emotions.

Today I looked up and in a rather odd location, on a rainy day, there is a huge male Luna on my window!! I cannot take another 5 years like the past! Anybody have any experience with multiple sightings over the years?

Sungsook Yang on June 11, 2020:

I saw a male Luna moth in May 2019 and June 2020 on a different hike trail. - What a delightful treat!

Was fortunate to discover one on the front porch of our home this afternoon. Incredibly beautiful, actually thought it was a few bright green leaves until I got a closer look. Wing tip to wing tip it is every bit of 4” wide. Never saw one before, but very glad I did. Actually got a few pic’s with my iPad that I would be more than happy to post. Toms River, NJ 6/10/20

Cheryl on March 30, 2020:

I'm looking at one right now, on my front porch. It was attracted to the light in my DynaTrap insect trap. I turned off my trap, and the gorgeous luna moth is resting on the ceiling of our porch. I'm not sure if its a male or female, but one of its long tails is torn. I'm praying that it has a chance to mate, so I will wait. This moth is stunning! Thank you for posting this information.

Russ on December 31, 2019:

I was fortunate enough to have seen a Luna Moth once when i was 14, which was 30 years ago! I'm hoping that this is because of their rarity and not from pesticides. Unfortunately i havent seen one since and their sea foam coloring is a favorite of mine too.

Paula (author) from The Midwest, USA on November 11, 2019:

Luna Moths are so lovely to see, aren't they? They are big enough to be noticed as well, so I am not too surprised your dog was curious. At least you got to see it's beauty before it flew away! Paula

Paula (author) from The Midwest, USA on November 11, 2019:

Hello Jenny, I am so glad you found the information helpful! As for leaving the cocoon alone, you may have saved it's life! Many people are beginning to take caterpillars and cocoons indoors in an effort to save the moth or butterfly from the elements. Sadly, what often happens is they emerge indoors and die anyway because they are now confused with the sunlight and temperature changes. Nature's way is best, and these critters are tough little guys! Thank you for sharing.

Paula (author) from The Midwest, USA on November 11, 2019:

Thanks for sharing! Sometimes they do that if they are cold. I learned that about moths from one of my favorite entomologists. Was it a bit chilly or cold by chance?

Jenny on October 08, 2019:

We have a Luna caterpillar cocooned above our front door in Newburgh, IN. We first saw the beautiful lime green (huge!) caterpillar on Sept 6 as it was beginning to spin it's cocoon. It was fully cocooned by Sept 8th. We had read where they only cocoon for 3 weeks and I was beginning to get nervous that it had died in the cocoon. Thank you for setting my mind at ease with this article (it says they can overwinter in the cocoon- whew!) We are so blessed to have this beautiful creature cocooned on our front door and my family and our friends are looking forward to watching it emerge! Thank you for the helpful information!

James on September 21, 2019:

I just saw my first. I live in central Texas.

Chris on September 10, 2019:

I had two Luna Moths on a Oak tree in my yard yesterday. I live in SE Kansas

Sandy on September 06, 2019:

I actually found the luna moth in its caterpillar state-and I took him to a nature center- where 2 weeks later he is in his cocoon. So neat to have found him and I am excited to see him emerge in the Spring into a luna moth!

Sharon on September 01, 2019:

I found my first Luna Moth . It was so beautiful. I thought it was a big green butterfly. I live in Tyler Texas. Wow it was so beautiful. My friends told me it was rare to see them. It only stayed about a day.

Anonymous on August 24, 2019:

Saw my first Luna moth two years ago, shortly followed by my second a few days later. I was surprised at how fast they flew! Knocking around into my porch light like a madman before whizzing off before I could get a real good look at them.

gordon kohl on August 22, 2019:

I have had a luna moth here for several days, however it appears to be dying. It keeps flipping on it's back and can't move it's legs. It just flops around. Can anyone tell me what is going on?

Kevin on August 20, 2019:

Im 32. Saw my first one a year ago in woodbury heights nj... definitely amazing to see..

Joan on August 17, 2019:

I have a large Luna Moth on an outside wall near my front door, it arrived 3 days ago and is still there. First time to ever see a Luna Moth and was in awe of the size and color and took pictures of it to show my family. A beautiful moth with a pretty color. I live in Millville, NJ

Wendy on August 09, 2019:

I just brought one in that was lying on the grass, in full shape. Will it

come to life sometime thru the day, or once it's in the grass it's life

is over? Judy, I'm in Maryland, too, Gaithersburg.

Judy on August 08, 2019:

I have one taking a break near my garage door. It has been there for 2 days. I think it laid eggs last night. It's August in Maryland. It is a lovely color.

Ann on August 06, 2019:

I saw one and photographed it! Very beautiful!

Chelsea on August 02, 2019:

I live in central Michigan a Luna moth caterpillar was in my yard, it has now turned into a cacoon. Just waiting for it to emerge from that stage to see it. I'm so excited! This is my first time seeing one.

Amy Stone on July 31, 2019:

I just found 5 of them in my front yard

Robin on July 26, 2019:

We had one land on our door under our large front porch. It's been there for two days. What a beauty!

LeAnn on July 24, 2019:

Had one land on me last night and stay for a half hour. He was so cool. Beautiful! I wish I could post pictures because I was able to get some really nice ones!! I live in central Alabama. They are everywhere here!

Alisa Pisarski on July 19, 2019:

I live in south west Michigan and had never seen a Luna moth until the 7 th of July. Crazy story! That morning while mowing I had hit small rock that went straight through my living room window leaving a 3-4 inch hole. Later that night about 11pm my 2 granddaughters and I heard somthing behind the blinds I had pulled down over the unfortunate hole in the window. To our amazement a Luna moth had come through the hole and began to fly around the room! at first the size startled us and we ran for cover

Margo s on July 18, 2019:

Just saw a Luna Moth on the kitchen window. Came calling just after midnight 19 July 2019 in Big Pond, Cape Breton, Nova Scotia.

Diane on July 16, 2019:

I get a Luna Moth almost every year on the building where I work, in Maryland. I always thought it was the same moth coming back year after year, not knowing the life span. I look forward to seeing this moth! I also have a pretty large brown and yellow one, along with a yellow and pink one and a brown smaller brown & yellow one each year. The larger brown & yellow one is here now along with the yellow and pink one. They are on the office window. The yellow and pink one has been here since Friday and the other one came yesterday. Your article was very informative. Thank you!

Becca on July 16, 2019:

I saw a huge Luna Moth at our boat dock in KY last month (June). I often wonder how they get so large, so fast.... And it is so sad that they only live a few weeks before dying. It seems like such a cruel existence after all the effort and struggle they go thru to be the beautiful amazing thing that they are !

Angela Berry on July 15, 2019:

Just saw one outside my apartment..i had to find out what is was..its huge..very warm tonight..i live in yukon oklahoma..

Cheryl on July 11, 2019:

We have a cabin in Murphy, North Carolina. We were there in April of this year and I have 3 Luna Moths on our covered deck. They hung out there most of the day. From what I have read, we were fortunate to see them.

Jett Scarlett on July 11, 2019:

I've seen a Luna moth 3 times that I can remember. All were in the city or suburbs in Cincinnati, Ohio. The first time was during the day. The moth was resting in the corner of a concrete window outside a record store in downtown Cincinnati, and I inadvertently disturbed it. The second time was about 6 years later. I was in the Clifton neighborhood of Cincinnati, sitting at a table with friends in a well-lit room, and a Luna Moth flew in the open window and landed on me. The third time was shortly after I moved back to Cincinnati. I was taking out the trash. There was a Luna Moth on the foundation of our house right behind the trash cans. The last time I saw a Luna Moth was over 30 years ago, and I would love to see another one. Like Eastern Bluebirds, Luna Moths seem to have gotten very rare.

Linda on July 10, 2019:

I just saw one on the side walk in Hampton, NB Canada I didn't want to see it get walked on so I took it over to the bushes and put it on the ground. Beautiful species.

Carla on July 09, 2019:

I had a few around my porch every summer until I accidently killed one and none have returned since. Luckily, I took some beautiful pictures of them while they were still visiting.

I on July 09, 2019:

I have one on my kitchen window right now in Glenfield NY.
