Ghost moths, also known as Hepialidae, are a fascinating family of insects that remain somewhat elusive, capturing the curiosity of both professional and amateur entomologists. Found globally, these moths are known for their unique characteristics, behavior, and appearance. Interestingly, their name is derived from their peculiar hovering flight patterns, which are quite ghost-like.
There is an incredible diversity of ghost moth species, boasting a wide range of sizes, colors, and patterns. As a result, there is always more to discover and learn about these enigmatic creatures. In addition to their captivating looks, ghost moths exhibit intriguing behaviors, such as their distinct larval feeding habits, which involve living in underground tunnels and feeding on plant roots.
To better understand ghost moths, we can explore aspects like their life cycle, habitat preferences, and their potential impact on agriculture and forestry. By delving into these topics, we gain valuable insights into this remarkable insect family and ultimately deepen our appreciation for the intricacies of the natural world.
Ghost Moth Basics
Classification
The ghost moth (Hepialus humuli) belongs to the family Hepialidae under the order Lepidoptera, which includes butterflies and moths. Members of this family are commonly called swift moths.
Physical Appearance
Ghost moths are known for their white wings, giving them a ghost-like appearance. The wingspan of a ghost moth is typically around 50mm.
Features of Ghost Moths:
- White wings
- Wingspan of around 50mm
- Distinct ghost-like appearance
Range and Distribution
These moths are primarily found in Europe, specifically in Great Britain. They are relatively widespread in these regions.
Distribution:
- Europe
- Great Britain
Habitat
Ghost moths mainly dwell in grassy habitats, as their larvae or caterpillars feed on the roots of grasses. The moth goes through a complete life cycle, including egg, larval, and adult stages.
Ghost Moth Life Cycle:
- Egg
- Larva (caterpillar)
- Adult moth
Comparison Table: Ghost Moth vs. Typical Moth
Feature | Ghost Moth | Typical Moth |
---|---|---|
Family/Order | Hepialidae/Lepidoptera | Lepidoptera |
Wings | White wings | Varied colors |
Wingspan | ~50mm | Varies |
Habitat | Grassy areas | Various habitats |
Main Food Source | Grass roots (in larval stage) | Varied |
Ghost moths are fascinating insects with ghostly white wings and a unique life cycle. Their distinct appearance and preference for grassy habitats make them an interesting subject of study within the Lepidoptera order.
Life Cycle and Reproduction
Mating Behavior and Lekking
Ghost moths, also known as ghost swift moths, are known for their unique mating behavior called lekking. Males gather in groups to perform an elaborate flight display, hovering and releasing pheromones to attract females. This usually occurs at dusk in open areas such as grasslands and woodland clearings.
Eggs and Caterpillars
After mating, female ghost moths lay their eggs on various plants, including grasses and bushes. The caterpillars, or larvae, hatch and feed on these plants and can be found in forests, grasslands, and other woodland habitats across Britain. Caterpillars exhibit some level of sexual dimorphism, with female caterpillars being larger than males.
Predators of the ghost moth caterpillars:
- Birds
- Bats
- Other small mammals
Pupal Stage
When the caterpillars reach their full size, they enter the pupal stage of their life cycle. The pupa is formed within an underground cocoon, usually close to their host plant. This stage can last several weeks before the adult moth emerges.
Adult Moths
Male Ghost Moths | Female Ghost Moths | |
---|---|---|
Size | Smaller than females | Larger than males |
Color | Yellow forewing | Orange markings on forewing |
Flight Range | Larger range during lekking | Lesser range |
Adult ghost moths are characterized by their distinct color patterns and size difference between males and females. Males tend to have a more extensive range during mating season, while females have a more limited flight range. The moths also share common predators, such as bats and birds, in their woodland habitat. Carl Linnaeus, a famous botanist and zoologist, first identified the species in 1758. Ghost moth adults have a relatively short lifespan, living long enough only to reproduce successfully.
Ghost Moth Significance
Folklore and Literature
Ghost moths, belonging to the family Hepialidae, are known for their intriguing role in folklore and literature. In Britain, these moths are associated with Ghost Month, a Taoist tradition also known as the Hungry Ghost Festival. The ghost moth’s English name derives from its appearance at dusk, when its white, translucent wings resemble ethereal spirits.
An example of the ghost moth’s literary significance can be found in Emily Brontë’s Wuthering Heights, where the moth symbolizes the novel’s haunting atmosphere and supernatural themes.
Conservation Status
The conservation status of ghost moths varies depending on the species. These moths are distributed across different woodland habitats and possess unique characteristics:
- Distinctive antennae
- White or translucent wings
- Nocturnal activity at dusk
A comparison table highlighting features and distribution:
Features | Ghost Moth |
---|---|
Antennae | Distinctive |
Wings | White/translucent |
Activity | At dusk |
Distribution | Woodlands |
Despite their fascinating cultural and ecological significance, there is limited information on the conservation status of many ghost moth species. Efforts to study and conserve these moths are vital for preserving the biodiversity of the celestial beings they have come to represent.
Avoiding Conflict
Dealing with Moths in the Home
It’s important to keep Ghost Moths from invading your home, as they might have an impact on the well-being of family members, especially children. Ghost Moths carry a reputation of negative energy, and handling them with care is key to maintaining harmony within the household. Here are a few short tips for managing their presence:
- Offerings: Placing offerings of food in secluded areas encourages good karma and might keep moths at bay. Just ensure these offerings are kept in clean and hygienic conditions.
- Ancestor worship: Displaying photos or amulets of ancestors around the house can create an aura of protection against negative energy.
- Colors: Decorating rooms with dark colors like black might discourage moths from entering, as they prefer lighter environments.
- Rock salt: Placing rock salt at entry points helps deter unwanted presences, moths included.
Here’s a concise comparison table to illustrate the pros and cons of using rock salt for moth prevention:
Method | Pros | Cons |
---|---|---|
Rock salt | All-natural and eco-friendly | Can be messy to handle |
Non-toxic to humans and pets | Might attract other pests |
In summary, maintaining a comfortable home environment without Ghost Moths requires the use of a variety of tactics. Following these methods may help create a balanced, positive space for you and your loved ones.

Try Hepialidae, a lot of Australian ones look like chubby awkward sphinx moths, maybe Abantiades sp.
I’ve seen these before ,its a giant wood boring moth from austrialia cossidae family subspecies
XYLEUTES or ENDOXYLA cant tell. Your moth is female hope this helps
Just as a matter of interest – the moths around Canberra are Bogong (not bogan) moths – Agrotis infusa.
Hi WTB, ROFL -query should have been about a BogonG Moth not a Bogan Moth (would love to see the latter: sporting a mullet, wearing acid-wash stretch denim jeans and uggs driving a clapped-out Commodore…). Moth named after Mt Bogong:
http://australianmuseum.net.au/Bogong-Moth
Bogan is a pejorative social descriptor: http://www.urbandictionary.com/define.php?term=bogan
This moth looks a bit too big to be a Bogong moth. If Ken really is in a bogan migration path he is very unfortunate.
This is prob rather late but only just seen this site. This is definitely a swift moth, and prob is Abantiades. Called rain moths as often come out after rain. Yours prob had just hatched and was still dr ying its wings
This is Sthenopis purpurascens.
Thanks so much Mardikavana. Your identification allowed us to do considerably more research on this fascinating Four Spotted Ghost Moth.
I think it’s most like a tiger morth.
Thanks Cesar,
Karl just sent a correction which identifies it as a Carpenter Moth.
I also found one of these moths in the south of Western Australia. It was lying in the road and actually laying eggs. Put moth and eggs with some vegetation in a jar for protection. She didn’t move but stayed alive for a week or so. Unfortunately the eggs didn’t hatch.
Perhaps she didn’t have an opportunity to mate.
Moth (dead). Brown 90mm long body, 22mm thick body covered in white fur, 120mm overall but ends of wings damaged. Wing span estimated, 200mm plus. I am from the bush I have never seen such a huge moth. I wish I could send photographs.
We wish you could send photographs as well. These large Australian Moths are truly fascinating creatures.
G’day cobber…
“Ghost moth” and “Swift moth” are common names for the Hepialidae in Australia.
The Cossidae (this sighting) are commonly called “Wood moths” or “Goat moths” because of the associated smell 🙂
Thanks for this clarification. Common names can be helpful when trying to make information on the natural world accessible to more people, but they are often deceptive regarding true identifications. We have changed the subject line of the posting.

So excited i found this page. I came across one this morning at the train station it was sitting on the steps so i got some photos of it. I’d love to send them. Such a pretty moth. Cute little face. Reminds me of a flying fox
Where Leiden? Where did you find it, London, Paris, New York. I found mine in Rockhampton Queensland. I would very much like to post a photo. Why can’t we post photos on this page? I am on f/b.
You may post images by clicking on the Ask What’s That Bug? link on our home page.
This moth is also in humboldt Saskatchewan , and seemed to have disappeared considerably , when the fire was thick by p.a these moths showed up basically covering walls completely , over the next three or four days they coated (the stems of tall grass and even electrical cords outlets and basically anything really ) in a thick black tar like substance , if you squish one they have black inside them also but attached are white blobls , looks like eggs honesty so it’s obviously it’s hatching process, what I’m curios to know is how in hello half acre is a guy supposed to get it off ? I work at an industrial wash bay , our water is 140 degrees celcius all day , doesn’t touch the tar , I have tried multiple cleaners , spray nine, citrus solve, pansolve ( can take practically anything off , tar from roadways comes off with pan solve but no not this moth tar ? It be cool to know what the heck it is , or made up of ? Is it harmful ?
Thanks so much. Clearly I need to figure out how to search better, I really did spend a lot of time looking. I wasn’t convinced that it was a sphinx moth, but that seemed closest. Now I know. In any case, I thought you might like the picture of both colors.
Yes, we are quite excited. This is a new species for our site.
Well, that head is really strange, but because of the body and horns, I am quite sure that this is a moth exuvia…

Thanks for those wonderful links Cesar. These images make if abundantly clear how little we really know about the world around us. We will change the subject line of the posting.
Thank you Cesar for the links and all the info. After looking at your images and additional links to your pages, I see many similarities with my molt. Your expertise is most welcome.

Wow, wow! Eric Eaton, I have your field guide! Along with a bunch more….. Thanks for your input. Here’s more pics. https://www.facebook.com/media/set/?set=a.10154138024641539.1073741837.720886538&type=1&l=2fa331e9bd
Cesar Crash who runs our sister site in Brazil, Insetologia, believes this to be a Moth Exuvia.
i just found one of these Moths on the NSW SOUTH COAST ..she was on the ground i picked her up and put her in a tree she started laying eggs ..i just came on to see if i could find what type of moth ,and found this site thank you ..
Congratulations on your sighting of this gorgeous Ghost Moth or Swift Moth in the family Hepialidae.
Just found one in Sydney, she’s laid her eggs, I don’t know what to do with them. Anyone? Such a beautiful thing.
Kevin,
I have the final answer! This is Carpenterworm Moth (Prionoxystus robiniae)
http://bugguide.net/node/view/283123
Marius Aurelian on BugGuide said “This is definitely a carpentermoth (family Cossidae) exuvium and i would bet it is Prionoxystus robiniae. Acossus populi seems to be less frequent and restricted to poplars, according to the U of A Strickland Entomological Museum page for this species. The other cossids are either much smaller or they do not feed on poplars or willows. I checked the link you posted and i noticed the 4th photo you took (lower right) is of a pupa about to emerge. Had you waited 15 more minutes you would have seen the adult coming out of the pupal skin. Amazing process! Of course, many times they fail to emerge and the pupal skin becomes their casket.”
I found one too in Maryland a week later last year, http://www.inaturalist.org/observations/5788894
Thanks so much for helping to solve this mystery.
I’m happy I could get to the family 🙂

Thanks Cesar.
I have a video of what I think may be a hawk or ghost moth laying her eggs. Please let me know your email address so I can send to you. Do you know if the larvae damage trees when they bore into them. Worried about my tree now I know how many eggs there are!
Just photographed one in the Blue Mountains NSW.
I saw one in blue mountains too, on the 24th after dark. Maybe the same one…all green no markings on the wing. Peach/ orange under wings or 2nd set of wings.
Do they eat one specific tree leaf? Found one on our deck, coastal Newcastle NSW.
