It is classified under the phylum Arthropoda, which encompasses insects, spiders, and crustaceans. The moth falls under the class Insecta and the order Lepidoptera, sharing this taxon with butterflies.

Here is a brief taxonomic hierarchy of the Spotted Apatelodes:

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Class: Insecta
  • Order: Lepidoptera
  • Family: Apatelodidae
  • Genus: Apatelodes
  • Species: Apatelodes torrefacta

Scientific Synonyms

The Spotted Apatelodes is also classified under the family Apatelodidae and the genus Apatelodes. It is important to note that there are no known scientific synonyms for this species. However, the genus Apatelodes comprises more than half of the known species in the Apatelodidae family.

Physical Attributes

Notable Features

The Spotted Apatelodes is a remarkable moth that stands out due to its distinct characteristics. Its hairy body is covered in a combination of black hairs and neon yellow, creating a unique and vibrant appearance. The forewings have a bright pattern that adds to its attractiveness.

Size and Colors

The size of Spotted Apatelodes varies, but they typically have a wingspan around 3 to 4 inches. As mentioned earlier, the moth is well-known for its striking coloration, which includes the following features:

  • A mix of black and neon yellow hairs on its hairy body
  • Bright patterns on its forewings

Keeping these physical attributes in mind, it’s easy to be captivated by the Spotted Apatelodes moth. Remember to admire these fascinating creatures from a respectful distance, as you enjoy their presence in their natural habitat.

Distribution and Habitat

Geographical Range

The Spotted Apatelodes (Apatelodes torrefacta) moth is a species native to North America. Its distribution spans from the northeastern United States to southeastern Canada, reaching as far as Maine and Ontario. The moth’s range extends southward, including states like Florida and Texas, and even reaching parts of Mexico.

Typical Habitat

Spotted Apatelodes call deciduous forests their home. These forests are characterized by trees that shed their leaves in the fall. You are likely to come across these moths in wooded areas with a mix of deciduous trees, as they provide ideal shelter and food for the larvae. Some common trees found in their habitat include oaks, maples, and hickory, often providing ample resources for the moth population.

Additionally, these moths are commonly attracted to light sources, making them easier to spot during nighttime hours. So, when exploring a deciduous forest during dusk or at night, don’t be surprised to find a Spotted Apatelodes fluttering by a nearby light.

Life Cycle and Generations

Stages of Development

The spotted apatelodes is a unique moth species with an interesting life cycle. The four main stages of development include egg, larva, pupa, and adult.

Egg: The life cycle begins with the female moth laying her eggs on the leaves of host plants. These eggs are typically small and spherical in shape.

Larva: As the eggs hatch, caterpillars emerge, starting the larval stage. During this phase, the spotted apatelodes caterpillars feed on the leaves and grow in size through different instars.

Pupa: After reaching their full size, the caterpillars form a protective cocoon around themselves, transitioning into the pupal stage. Inside the cocoon, the caterpillar transforms into a moth.

Adult: Once the metamorphosis is complete, the adult moth emerges from the cocoon and starts looking for a mate to reproduce and continue the cycle.

Season and Generations

Spotted apatelodes moths typically have one generation per year. The specific timing of these life stages depends on the region and climate.

  • In warmer climates, eggs are laid in late spring, and adult moths emerge in summer.
  • In cooler climates, eggs are laid later in the season, and adult moths may not emerge until early fall.

Due to their unique life cycle and fascinating stages of development, spotted apatelodes moths are a captivating species to observe and study.

Diet and Feeding Habits

Caterpillar Diet

The Spotted Apatelodes caterpillar mainly feeds on the leaves of various deciduous trees. For instance, they can be found munching on the leaves of:

  • Oak trees: Oak leaves are a favorite among caterpillars due to their nutritional value.
  • Maple trees: Another popular choice, maple leaves are rich in nutrients, too.
  • Cherry trees: The caterpillar enjoys cherry tree leaves as well, benefiting from the fruit’s rich nutrients.

You might notice the caterpillar has variety in its diet, allowing it to thrive in different environments with diverse tree species.

Adult Moth Diet

As an Adult Moth, the Spotted Apatelodes changes its feeding habits. Instead of leaves, it now prefers:

  • Floral nectar: Adult moths seek out flowers to feed on the sweet nectar, giving them much-needed energy.
  • Tree sap: Another source of sustenance for the moth, tree sap provides nutrients and sugars for nourishment.
Life Stage Diet
Caterpillar Oak, Maple, and Cherry leaves
Adult Moth Floral nectar and tree sap

Remember to be mindful of the Spotted Apatelodes’ feeding habits when observing them in nature, as their diet differs between life stages.

Identification Guide

Caterpillars Identification

Spotted Apatelodes caterpillars belong to the phylum Arthropoda, under the class Insecta. To identify these larvae, pay attention to these features:

  • Distinct black, gray, and white bands on their body
  • Long, silky, black hairs that extend outward from the bands

These caterpillars are a part of the animal kingdom, and as they grow to maturity, they transform into a beautiful moth.

Moth Identification

The adult Spotted Apatelodes moth exhibits unique characteristics:

  • Distinguishing creamy white wings
  • Velvety appearance
  • Intricate dark brown spots on its wings
  • A robust body with a furry tail

Becoming familiar with these distinct features will make it easy for you to identify Spotted Apatelodes moths in the wild. Enjoy your journey through the fascinating world of these insects!


In summary, the Spotted Apatelodes is a fascinating moth species with its distinctive markings and hairy appearance. As a nocturnal insect, they play a significant role in the ecosystem by helping with pollination during nighttime hours.

Remember to always approach these moths with care and respect, as their presence contributes to a balanced environment. Becoming familiar with the Spotted Apatelodes and other moth species helps raise awareness about the importance of biodiversity in your surroundings.

So next time you spot a Spotted Apatelodes fluttering around, take a moment to appreciate its unique beauty and the diverse world of moths it represents.

Hi Michelle,
The silhouette of the Spotted Apatelodes,

Sphinx Moth of Some Kind?
Hi Bugman;
We live in East Tennessee and my wife Jannett saw this moth on our garage wall. It was over my head, that is the reason for the silly angle of the attached pictures. I did capture it in a clear jar to see if I could get a better shot, but the poor thing just about beat itself to death trying to get out of the jar. So I let it go before getting a ‘head on’ picture. Is it possible for you to identify the critter from the attached pictures? Thanx;

Hi John,
Even though it looks like a Sphinx Moth, the Spotted Apatelodes is really in the family Bombycidae, the Silkworm Moths.

What the heck is this?
Hope you can help us. My sister-in-law found the following "insect" on the siding outside of her house yesterday. None of us have seen anything like it before. It appears to be about an inch or two long. We live in Cape May County, NJ. Any info you have on it would be greatly appreciated.
Maureen Cawley

Ed. Note: The string of family emails also contained the following gems of wisdom.

Does anyone know what the heck this is? It was on the back wall of our house yesterday. He’s kind of cute, provided he doesn’t get bigger and bigger and start devouring us. (Troy, please show pics to Emmett. I told him about it and said I’d take pictures.)

I zoomed the pictures and brightened them a bit so I could more accurately identify this interesting specimen. I came to the conclusion that…I have no friggin’ idea what this is. But it seems you got a great picture of its butt. That’s what you get for moving “off-shore”. The Cape May County Mosquito Commission no doubt exterminated all of these little suckers from the island years ago…It probably had something to do with the clouds of DDT they would spray through the streets. (Which I would subsequently run through with my toy guns playing “army man”…That could explain some things, eh? Like the headaches.) Anna says maybe it’s a baby bat. Katie says a baby butterfly. Emmett’s vote: Some kind of bug (boring). And Maureen says you should alert FEMA and not go outside for 6 months. I think you should have smushed it. That’s a term entomologists use for what they do with bugs that are “icky.”
P.S. I will research this extensively this evening, provided thunderstorms don’t rip through South Jersey and keep me busy with actual work. Yuck.

Dear Maureen, Emmett, Anna, Katie and Troy,
We think this is a Spotted Apatelodes Moth, Apatelodes torrefacta. This moth ranges from Canada to the Southern state and west to the Mississippi River. It is relatively common in the Appalacian region.

Letter 6 – Spotted Apatelodes


Possible Amorpha juglandis?
Dear "What’s That Bug?",
I was walking outside to get the mail this morning, and I noticed this bug on my front door. At first, I didn’t know if it was real or not, due to trick that people in my family like to pull, but when it moved I realized that it wasn’t a fake. At the same time, I had never seen this sort of bug before, and really had no idea what it was. After doing a bit of research, it seems to be quite similar to the Amorpha juglandis, but there are still some differences that make me wonder, and the sites didn’t say that they were found in New York, where I live. No one I’ve asked so far has been able to tell me what it is, and so I was wondering if you could clear things up. Attached to this email is a photo of the bug, and I have a few others posted on my DeviantArt page ( ), if that one doesn’t help, since it’s from the back. If you can identify this, I’d really appreciate it. Thanks a lot! Sincerely,

Hi Jessica,
This is a Spotted Apatelodes, Apatelodes torrefacta. We like checking BugGuide’s Data pages for range information (since they are a much more thorough, organized and scientific site than our own), though their information is based on submissions to their website. There is not a submission from New York, but there are submissions from many adjacent states as well as Canada. If you submit your image to BugGuide, the range information will be more complete.

Thanks! You identified a Spotted Apatelodes Moth for me.  No description or photo would fit it. I kept saying that it looked like bark. I may have seen a butterfly the other day that resembled it, but this morning was cool, and it was tired. I was able to pick it up, and was able to get a close look at it. Still looks like bark, but I noticed the feather antennae, and the curved abdomen. This evening I found your site.  So I am very excited. You will look long and hard for an image of it, because… it looks like bark. I put it onto an arbor vitae, so maybe I’ll be able to get a photo tomorrow, if it is still there. Peace!

This moth bug was sitting on my back patio so I grabbed the camera and took 2 pics of it front and back. It looked like a baby bat at first but I also saw an Indian luna moth as well in the following days. I live in Central Florida but my backyard is next to a nature preserve so it is very lush. Can you help identify it? It resembles the oleander hawkmoth in some features but not exactly.

Thank you for the information! Also, we did some digging and found that it comes from a “saddleback that true? If so, that is a very interesting looking caterpillar!

Where did you do your research?  It is not correct.  The caterpillar of the Spotted Apatelodes is yellow and fuzzy with longer black tufts and it can be viewed on BugGuide, and excellent source for information on North American insects.  The Saddleback Caterpillar develops into a very different Saddleback Caterpillar Moth which we just posted for the first time this week.

Letter 23 – Spotted Apatelodes did not molt into Inverted Y Slug Moth


Subject: Mysterious moth that molted and got smaller?
Location: Pennsylvania
June 19, 2014 5:06 pm
Yesterday when I got to my office, there was a 1.5″ wide brown moth attached to the screen door. It was pretty cool looking, so I took a picture. It stayed there all day as people came and went, without so much as a flutter. The next day when I got to work and looked at the door, I saw the smaller yellow/orange moth attached in the exact same spot. It hung around for a bit, and then was gone; I’m guessing that it got bored and flew off. I’m wondering if they are the same bug that molted or somehow changed from the large brown into the smaller yellow? Or is it just a pure coincidence that they were both at the exact same spot? It’s got me pretty intrigued, and I keep looking around the internet and can’t seem to find any information. Thanks!

Dear Jeremy,
What an interesting question you have posed.  You are under a misconception that moths (and possibly butterflies) will molt.  Molting is a process undergone by the immature caterpillars, and the final molt occurs when the adult moth emerges or ecloses from the pupa.  The large moth you saw originally is a Spotted Apatelodes.  We are not certain of the identity of the smaller orange moth, but it may be in the family Geometridae.

Hi Damisha,
This is a Moth known as the Spotted Apatelodes,
Apatelodes torrefacta, and it is perfectly harmless.  They do not even feed as adults since they do not have working mouth parts.  We are intrigued that they have appeared in such numbers.  According to BugGuide, the caterpillars feed upon the leaves of “ash (Fraxinus), cherry (Prunus), maple (Acer), oak (Quercus).”   Perhaps you had a large caterpillar population last season on your nearby trees, and though you did not notice the caterpillars, they eventually metamorphosed into a new generation that recently emerged as adults.  Here is a link to a photo of the Caterpillar.  Does it look familiar?

Dear John,
We do not believe this is a Prominent Moth in the family Notodontidae.  Your moth reminds us very much of the North American Spotted Apatelodes, one of the Silkmoths in the family Bombycidae, but we have not had any luck locating a matching image on the internet.  We will continue to research your request, and we will also enlist the assistance of our readership. 

Thanks very much. Prominent was just a guess as it looks vaguely similar to the ones we have here in the UK. I would be very interested to know the results of your research.

Julian Donahue responds
Hi Daniel,
Try Mimallonidae.

Despite Julian’s suggestion that we research Sack-Bearer Moths from the family Mimallonidae, a family also represented on BugGuide, we have not had any luck with a species.  The family is well represented on Discover Life, but no images match the submitted image.  We did however locate this pdf  on ttfnc entitled On the Number of Moths (Lepidoptera) that Occur in Trinidad and Tobago by Matthew J. W. Cock, and we suspect we may find the answer there if we hunt more.  We will attempt to contact the author, Matthew J.W. Cock for assistance.

Hi again Daniel
Having just looked up Spotted Apatelodes on the web and seen some pics, it reminds me of a moth pic I took at the same place and time as the one I submitted. I attach a very poor pic of it.  I can’t find any evidence that Spotted Apatelodes is found in Trinidad – but it might be closely related.

Same or Different Species???
Same or Different Species???

Thanks for the update John,
This new image does support our initial impression that your moth may be in the family Bombycidae, and we wonder if both of your images are the same species.  When conditions are right, moths (and other insects) from the same species emerge simultaneously which benefits the species as individuals have a better chance of locating a mate.  Since your two images were taken “at the same place and time” we suspect they are the same species as there are similarities in the overall structure, though the markings are not evident on the second image.  Hopefully Matthew J. W. Cock will respond to our request after we located his contact information on the internet.

Julian Donahue supplies additional information
Mimallonidae used to be called Lacosomidae.
But on second thought, and after reviewing the attached PDF (where you can see images of mimallonids–they all pretty much look alike), I think that this moth is a geometrid (forewing cubitus vein appears to be 3-branched).
Here’s the attachment!  15465-5006-1-PB

Thanks Julian,
I have also written to Matthew J.W. Cock who wrote this article.

Dear Daniel
This is a male of what I am calling Apatelodes nina (Stoll) sp. (Apatelodidae).  However, this is a genus and family that needs revision with many undescribed species, so things may change when further work is done.
Kind regards, Matthew

Thank you for your help.  I’m impressed at the speed of your replies!

  3. My grandson and I found one of these on Oct. 7 and put in in a clear plastic container with leaves and airholes so he could watch it. The next morning it had formed a cacoon.
