Prominent Moth: All You Need to Know in a Nutshell

folder_openInsecta, Lepidoptera
comment34 Comments

Prominent moths are a group of fascinating insects that can be found throughout North America. These creatures have chunky bodies and are often camouflaged in gray or brownish colorations. Their heavy covering of scales gives them a fuzzy appearance, while their heads and thoraxes often showcase contrasting colors. When at rest, they display unique behaviors including holding their wings over their body like a roof or curling their wings around their abdomens, which are lifted at an angle to the substrate they’re on [1].

There are 14 species of prominent moths belonging to the genus Datana in North America, and each is distinct in its own way. All of these species resemble dried leaves and have fuzzy, dark, rusty heads [3]. Some prominent moths, such as hawk moths or sphinx moths, belong to the Sphingid family, which includes some of the largest moths in the world. These amazing creatures have long, narrow wings and thick bodies, allowing them to be fast flyers and highly aerobatic [4].

Moth Classification

Kingdom Animalia

Moths belong under the Kingdom Animalia, which consists of multicellular organisms possessing traits like mobility and heterotrophy. Moth’s are closely related to butterflies, although there are distinct differences in features and behavior.

Phylum Arthropoda

Arthropods are characterized by their exoskeleton, segmented body, and jointed appendages. Both moths and butterflies fall under this category due to sharing these traits.

Subphylum Hexapoda

Hexapoda is a group containing all insects, including moths and butterflies. They possess three pairs of legs, which is a common characteristic of insects.

Class Insecta

Moths, as insects, belong to Class Insecta. Insects have three distinct body regions: head, thorax, and abdomen.

Order Lepidoptera

Lepidoptera refers to the group containing moths and butterflies, characterized by their scaled wings. However, there are subtle differences between them:

Feature Moths Butterflies
Antennae Feathery or saw-edged Club-shaped with a long shaft and a bulb at the end
Flight Active at night (nocturnal) or day Primarily diurnal
Wing position Hold wings over their bodies or curl around abdomen when at rest Fold wings vertically over their backs when at rest

Superfamily Noctuoidea

Moths fall under the Noctuoidea superfamily, whereas butterflies are classified under the Papilionoidea superfamily. The main difference is the families included under their respective superfamily.

Family Notodontidae

Prominent Moths belong to the family Notodontidae, which consists of moths with:

  • Chunky bodies
  • Camouflaged, gray or brownish colorations
  • Heavy covering of scales for a fuzzy appearance
  • Contrasting head and thorax colors

Examples of prominent moths include the spotted datana, gray furcula, and walnut caterpillar moth (source).

Main Characteristics


Prominent moths have a wide range of wingspans depending on the species. However, they are known for their long wings, which can be seen in many of the 3,800 species within the family Notodontidae 1. Some examples of prominent moths with distinctive wingspans include:

  • Spotted datana
  • Gray furcula
  • Variable oakleaf caterpillar moth
  • Walnut caterpillar moth

Nocturnal versus Diurnal

Moths can be classified as either nocturnal (active during night) or diurnal (active during day). Most moths, including prominent moths, are nocturnal and play a crucial role in pollination during the night 2.

However, there are exceptions as some moths are also active during the day. Different species of moths adapt their behavior and preferences according to their environments and food sources. This variety contributes to their vast diversity and prevalence across the globe.

Life Cycle and Habitat


Prominent moths begin their life cycle as eggs, laid by females on host plants. These eggs are often hidden on the underside of leaves, providing protection from predators and harsh weather. Example host plants where eggs are laid include:

  • Oak trees
  • Maple trees
  • Huckleberry plants


Once the eggs hatch, the larvae (or caterpillars) emerge and begin to feed on the host plant’s leaves. As they grow, they go through several stages (called instars) and shed their skin to accommodate their increasing size. Some larvae have a unique relationship with ants, which provide them protection in exchange for sugary secretions. This mutualism between larvae and ants can be beneficial in the garden, as ants may help control other pests.

Range and Distribution

Prominent moths are found in various habitats across North America, including forests, meadows, and gardens. Their range spans from Canada down to Mexico, making them a common sight in many environments across the continent. Despite this broad range, the distribution of specific species within the prominent moth group may be more limited due to their differing host plant preferences.

Location Common Prominent Moth Species
Canada Actias luna, Cerura vinula
United States Datana integerrima, Nerice bidentata
Mexico Euchaetes egle, Syntomeida epilais

Overall, the life cycle and habitat of prominent moths are diverse, with different species demonstrating unique adaptations to thrive in various environments across North America.

Notable Species

Nadata Gibbosa

Nadata gibbosa, also known as the rough prominent, belongs to the Notodontidae family of moths. These moths are characterized by:

  • Chunky bodies
  • Generally gray or brownish colorations
  • Fuzzy appearance due to heavy scales

This species is commonly found in North America, with adults having a wingspan of 35-50mm. They can be spotted around hardwood trees, particularly oak, where their caterpillars feed on leaves.

Other Prominent Moths

Apart from Nadata gibbosa, there are many other species of prominent moths, such as:

  • Spotted datana (Datana perspicua): Commonly found in deciduous forests, the caterpillar feeds on various types of trees.
  • Gray furcula (Furcula cinerea): Inhabits mixed hardwood forests, the caterpillar feeds on willow and poplar trees.
  • Variable oakleaf caterpillar moth (Lochmaeus manteo): Distributed throughout North America, the caterpillar feeds on oak and sometimes other deciduous trees.
  • Walnut caterpillar moth (Datana integerrima): Commonly found in eastern North America, the caterpillar feeds on hickory and walnut trees.

Comparison between rough prominent and other species:

Feature Nadata Gibbosa (Rough Prominent) Other Prominent Moths
Habitat North America, hardwood forests Varies, mainly deciduous forests
Size 35-50mm wingspan Varies depending on the species
Host plants Oak trees Different types of deciduous trees

In summary, prominent moths are a diverse group, and species like Nadata gibbosa have distinct characteristics and host plants. These moths are essential for maintaining the ecological balance in their habitats.

Food and Pest Management

Dietary Preferences

Prominent moths are known to feed on a variety of plants and materials. Some common food plants include:

  • Flowers
  • Nuts
  • Pears
  • Other fruits and vegetation

In some cases, prominent moths can cause damage to wool, as their larvae feed on the fibers.

Companions and Pests

Moths can co-exist with other insects or even potentially benefit from companion plants. Some examples of companions for moth-infested areas are:

  • Lacewings: predators that feed on moth eggs and larvae
  • Parasitic wasps: these wasps lay their eggs within moth larvae, eventually killing them

Prominent moths can also be considered pests, depending on the species and situation. For example, the Spongy Moth is a significant pest that poses a threat to North American forests, while the Indian Meal Moth is a common pantry pest.

Companion Benefit Pest Problem
Lacewing Feeds on moth eggs and larvae Spongy Moth Threat to forests
Parasitic Wasp Kills moth larvae Indian Meal Moth Spoils food in pantries

One effective way to manage moth populations is by using Integrated Pest Management (IPM), a combination of common sense practices and pest control methods that reduces reliance on pesticides.

Identification and Resources

Genera and Synonyms

Prominent moths belong to various genera within the family Notodontidae. Some common genera include Furcula, Nadata, and Datana. It’s essential to learn about the genera and synonyms to facilitate the identification process. Here are a few features to help identify prominent moths:

  • Chunky, camouflaged bodies
  • Gray or brownish colorations
  • Fuzzy appearance due to scales

Taxonomic Changes

Over time, taxonomic changes may occur as experts discover more information about moth species. Keep updated on these changes to maintain accurate identification and improve understanding of prominent moths.

Internet References

There are numerous internet resources available to help you identify prominent moths and learn more about their biology. Some reliable websites are:

  • Moth Photographers Group — Plates Series: Offers a large collection of moth images to study their appearance and characteristics.
  • PNW Moths: Contains information on more than 1,200 species of moths found in the Pacific Northwest, along with high-resolution photographs and an interactive identification key.

Utilizing these resources and observing prominent moths under various conditions, such as different lights and environments, will help you in the identification process.

Letter 1 – Prominent Caterpillar


Bright Pink Caterpillar/Worm?
Location:  Caneyville KY
August 28, 2010 2:39 pm
This little guy was found in Caneyville Kentucky. He is approximately 1-2 inches long, bright pink in color, an orangish face with two little black eyes very close together. I cannot see any legs, so I suppose this could be some sort of grub worm? Any ideas?

Prominent Caterpillar

Hi Ashlee,
We knew immediately that this was a Prominent Moth Caterpillar in the genus
Heterocampa, but we needed to browse BugGuide to determine the species.  We are quite confident that this is the Caterpillar of the White Blotched Heterocampa, Heterocampa umbrata, and we even found an identical color match on BugGuide.  The normally green caterpillar changes color just prior to pupation.

Signature: Blu caterpillar

Unknown Blue Caterpillar

We cannot provide a conclusive identification.  We did locate this very different looking blue caterpillar on BugGuide, and it is unidentified.  We suspect this is some type of Cutworm, the caterpillar of a moth in the family Noctuidae.

Karl Provides an Identification:  White Dotted Prominent Caterpillar
Hello Daniel and Blu caterpillar:
By any chance, was this caterpillar found on an oak tree? If so, I believe it may be White-dotted Prominent moth caterpillar (Notodontidae: Nadata gibbosa). The description according to ‘Caterpillars of Eastern North America’ (Wagner 2005), includes “Sea-green to waxy blue-green, stocky caterpillar, with weakly developed subdorsal stripe; densely salted with white dots. Head enlarged, pale green; mandibles yellow with black tips. Anal plate edged with yellow.” The angle of the shot makes it difficult to make out with certainty, but I think I can make out a hint of yellow at both the front and back end.
Regards, Karl

Thanks Karl,
Before cropping the image, our editorial staff can attest to the leaf in the image being an oak leaf.  This BugGuide posting looks like a perfect match.

Letter 3 – Two Caterpillars from Puerto Rico: Silverking Butterfly Caterpillar and Prominent Moth


Caterpillars from Puerto Rico (moths?) Sun, Jan 25, 2009 at 7:18 AM
These caterpillars were photographed in the humid karstic forest of northern Puerto Rico. The one with the “horns” is huge. I found it on a Piper shrub (Piperaceae), and the several I’ve seen are always out at night. At first I thought it would be a species of Heraclides (Papilionidae) but after checking some pictures, I decided it can’t be. I was photographed in summer (though seasons i Puerto Rico are not well defined, except rainy/dry).
The other caterpillar was shot by day, in the same general habitat. I was photographed just a couple of weeks ago.
I have a lot of unidentified insects in my website on Caribbean Natural History ( ). If it is OK with you, perhaps you can pay it a visit and provide me with any corrections/information you might think is relevant.
Thanks a lot for your kind help.

Unidentified Puerto Rican Caterpillar:  Prominent Moth???
Silverking Butterfly Caterpillar

Hello again Alejandro,
We fear we are not really being of much assistance to you today. In our humble opinion, we would guess that these might be Prominent Moth Caterpillars in the family Notodontidae. You can see some North American specimens on BugGuide. Many Prominent Moth Caterpillars have unusual projections on their bodies similar to the ones on both of your specimens. We will post your photos in the hope someone can assist in the identification. We will also link to your marvelous website and hope your site doesn’t crash from the additional traffic.

Hi Daniel:
I haven’t been able to identify the first image but I believe the second one is of a Prominent moth in the genus Nystalea, probably N. collaris. The web site for Area de Conservación Guanacaste (ACG) has a huge searchable database of moth (adult and caterpillar) images, including many for the various instars and color phases of N. collaris. The species ranges from southern Texas to Costa Rica, and the Antilles. Regards.

Update: February 13, 2009
Greetings Father Sánchez,
Since my research is limited to the early stages of butterflies (not enough hours in a day to add moths), I can only identify your first photo. It is a caterpillar of the Silverking butterfly, *Archaeoprepona demophoon* (Nymphalidae, Charaxinae), which feeds on several genera in the Lauraceae, its presence on *Piper* a result of wandering. As you discovered, *Heraclides* swallowtail larvae look entirely different and more or less like this:
Best wishes,
Keith Wolfe

Update: Sat, Feb 14, 2009 at 8:05 AM
The caterpillar in the first image is not a Prominent moth, but a Leafwing butterfly (Nymphalidae : Charaxinae). It is a Two-Spotted Prepona (Archaeoprepona demophoon); not to be confused with the One-Spotted Prepona (A. demophon). The name Silverking may be more common in the Antilles. The distribution of A. demophoon is from Mexico to northern Argentina, including the Caribbean. Within that area the genus is broken down into at least 10 sub-species, each with its own fairly distinct distribution. The variety found in Puerto Rico (and apparently nowhere else) is A. d. ramorosum. The ACG site mentioned above has numerous images of A. demophoon caterpillars and adults. Regards.

Letter 4 – Black Rimmed Prominent


Subject: Black Rimmed Prominent

This distinctly-patterned moth is the Black Rimmed Prominent (Pheosia rimosa). It can be found throughout North America. Evidently there’s another color morph, with a darker pattern, that was formerly considered a different species–you can see it on Bugguide. The young feed on aspen and willows. This adult showed up on a window after a warm late-June night.

Black Spotted Prominent Caterpillar

Dear Rebecca,
We started by searching the Owlet Moth Caterpillars on BugGuide, and then progressed to the Prominent Caterpillars.  Eventually we identified your Black Spotted Prominent Caterpillar, Dasylophia anguina, on BugGuide.  Distinguishing features according to Craig Biegler on BugGuide
include:  “the black ‘shoulder’ spot, shiny black ‘button’ on A8, raised rear end, elongated anal prolegs.”  The Caterpillars of the Eastern Forests website indicates:  “Splendidly rendered in shiny lavender, orange (or red), yellow, and black; both color and pattern variable. Head orange and unmarked. Middorsal and 2 or 3 subdorsal and supraspiracular stripes, these thin, broken, and black; subdorsal stripe orange, broad; spiracular stripe lemon, broad. Eighth abdominal segment with black dorsal button. Subventer with line of raised shiny black spots just above legs. Food: lead plant, locusts, and other legumes. Caterpillar: June to October; apparently 2 generations.”

Drexel's Datana Caterpillars

Dear Angela,
The defensive posture you have described and photographed is consistent with the Prominent Caterpillars in the genus
Datana, and the food plant and the coloration indicate that your specimens are Drexel’s Datana, Datana drexelii, which is described on BugGuide.

Thank you!!  I’ve been trying to find out what tese are ever since I first saw them!  I really appreciate your help.

Mottled Prominent Caterpillar

Dear L. Jones,
We really must commend you on figuring out that this is a Prominent Moth Caterpillar from the family Notodontidae.  We believe it resembles this Mottled Prominent,
Macrurocampa marthesia, that is pictured on BugGuide.  According to BugGuide:  “larvae feed on leaves of beech, maple, oak, and other deciduous trees” so the trees you observed most likely have provided a food source for your individual.

Wow. Exactly! A bit embarrassed I missed that. Thanks a bunch!

The Oval-based prominent moth (Peridea basitriens) is overall a rather dull gray. What makes it stand out are the oval/almond shaped rings/patches that surround its fluffy ruff. It almost makes it look like a stained-glass window. Thus says Bugguide: it has a wingspan of 3-3.5 cm, and it appears to occur here and there throughout the Easter US. I saw several last night, so moth-hunters here in Michigan, keep an eye out for this nifty moth!

Pre-Pupal Drab Prominent Caterpillar

Dear Molly,
Your caterpillar bears an uncanny resemblance to a Mottled Prominent Moth Caterpillar we just posted, except that individual is green and yours is pink.  Many caterpillars change color just prior to pupation, and that pre-pupal state is often a change in color from green to pink.  We located this image of a pink Mottled Prominent Caterpillar on BugGuide and we consider that an anfirmation of our suspicion, but, closer inspection has us doubting that since your individual is lacking the rear-end projections visible in this BugGuide image and our own image. We still believe this is a Prominent Moth Caterpillar from the family Notodontidae.  We now believe, based on this BugGuide image, that it is a Drab Prominent Caterpillar,
Misogada unicolor.  According to BugGuide, the:  “larvae feed on cottonwood and sycamore” and “larvae can be found on the underside of cottonwood and sycamore leaves April-September.”

Probably Prominent Moth Caterpillar

Dear Andrew,
We have yet to find an image that we can use as an identification, but our suspicion is that this is the Caterpillar of a Prominent Moth in the family Notodontidae.  Perhaps one of our readers will have more luck than we have had.

Thanks so much for the efforts. I am trying to get a few more pictures to ease identification.

caterpillar ID
Hi, we need a little help identifying this caterpillar. We found it moseying across our driveway this afternoon (we live in mid-Missouri). My daughter wants to keep it to see it transform, but I told her we can’t unless we can find out what it is and what it needs to eat! thanks for any help,

Hi Ramona,
You have one of the Prominent Caterpillars, probably from the genus Heterocampa. They have a distinct saddle pattern on the back which your photo illustrates nicely. There is some variability in coloration. I would recommend looking at the site Caterpillars of the Eastern Forests. If I were to try an exact identification, I would say the Oblique Heterocampa (Heterocampa obliqua) . The caterpillar feeds on oak.

My wife found this walking on paving in our back yard in Vancouver, British Columbia. May have arrived on new plants brought from nursery. We have looked at every single caterpillar pic on the web (feels like) but have failed to see anything even close. It doesn’t want to eat or spin a cocoon, but we’re hoping it will pupate so that we can see what emerges. But in case it doesn’t, we’re hoping you can tell us what it is.

Good Morning Pierre,
This is a Prominent Moth Caterpillar in the family Notodontidae, probably in the subfamily Heterocampinae.  We have not had a chance to do a more thorough search for its species identity, but we are posting the image in the meanwhile.  Many caterpillars turn pink just prior to pupation, and the color is not necessarily diagnostic.  See BugGuide for possibly genera in the subfamily.

Prominent Caterpillar

Dear Kate in Texas,
This is a Prominent Caterpillar in the family Notodontidae, and we spent a considerable amount of time trying to get a species identification for you.  The closest visual match we found on The Moth Photographers Group is
Schizura badia, though we are not certain that is correct.  According to Discover Life, the common name is the Chestnut Schizera, and the same common name is used on BugGuide where it states “The larvae feed on Northern Wild-Raisin and other Viburnum species.”  The Red Humped Caterpillar, another member of the genus, is known to feed on redbud, but your caterpillar is most definitely not that species.  Scientists and naturalists don’t always have comprehensive knowledge of the feeding habits of caterpillars.  Leaf loss due to caterpillar feeding is rarely a concern for a healthy tree.

Hi Jennifer,
Your caterpillar is one of the Prominent Moth Caterpillars in the genus

Prominent Caterpillar: Lirimiris truncata

Dear Len,
One of your newly attached images is a much nicer image of the “Arizona Devil” you sent earlier and we will be adding that image to the previous posting.  We are really excited about the yellow and orange caterpillar images you submitted.  We quickly identified them as
Lirimiris truncata thanks to The Firefly Forest site where it states:  “Lirimiris truncata caterpillars are bright yellow and tiger-striped with black and white, and they have a few patches of white bristles, a red head, and an even larger red tail hump. This large tail hump might function as a false head meant to divert predators’ attacks away from the more vulnerable actual head.  The garish coloration of Lirimiris truncata caterpillars makes them highly visible to birds and other predators, but these caterpillars’ bold yellow, red, and black colors are actually a universally recognized type of aposematic (warning) coloration meant to warn away potential predators. I don’t know if these caterpillars are actually poisonous or noxious, but many caterpillars in the same family have chemical defenses and can spray foul-smelling, irritating, or toxic fluids if disturbed. Noting this caterpillar’s bright warning colors, I didn’t try handling it.”  We verified that identification on BugGuide where it states:  “The placement of this species is Notodontidae is uncertain. Lafontaine and Schmidt listed it as incertae sedis in their 2010 checklist (1). BOLD places it under Dicranurinae.”

Prominent Caterpillar: Datana perspicua

Hi Marilyn,
We apologize for not responding to your original email.  We are totally swamped with identification requests at this time of year and our small staff cannot handle every identification request.  This is a Prominent Caterpillar in the genus Datana, and the behavior you describe of raising their heads and rear ends is typical of this genus.  We believe we have correctly identified your species as Datana perspicua thanks to this image on BugGuide which shows a group of caterpillars feeding on Sumac.  Thank you for your patience.

Prominent Caterpillar: Datana perspicua

Daniel, thank you for the confirmation of my caterpillar ID. I was conflicted when I cross referenced other images of this species on the Bug Guide. Some images showed images of Datana perspicua being black and yellow and labeled as final or penultimate instar. Other images with the coloration my caterpillar were labeled as 25mm, mid-instar. Mine was twice that size and I have several in a jar that have burrowed into the dirt to pupate, so they were the final instar. That conflicts with labels of the black and yellow caterpillars. Could those have been mis-labeled or mis-identified? Considering the time of year, are my pupating caterpillars likely to emerge this year for a second brood? Any guess on how long they will pupate if they do emerge this year? It will be good to have the adults to submit with the caterpillars when I submit any photos.
Thanks so much for your time, I realize you are overwhelmed at this time of year. I have now registered with the site and will contribute some $ to it, because it is AWESOME! Thanks again.

Hi again Marilyn,
Thanks for the donation.  Wow, where to begin with your questions.  We are going to take license and just speculate without researching for now.  Actually, reheated homemade ravioli sounds like just the thing needed before we begin. …

…  We have an opinion on the coloration discrepancy you describe.  We believe these Datana perspicua have a documented color match on BugGuide.  We believe the species is most likely variable in coloration between races and perhaps within the same brood as well, though we cannot recall having ever seen a photograph where a single Datana individual was differently colored than its siblings.  We also believe that caterpillars that bury themselves to pupate often have longer periods of dormancy and most likely more climate specific eclosion requirements.  We do not believe this Datana Caterpillar has multiple generations per year so we would expect a winter pupation, but we may be wrong.  The homemade spinach and ricotta ravioli in garden fresh pesto was yummy.

My 6 year old daughter, Ocean Rose, had this very special find in our backyard on September 2, 2012. I’m thinking they may be Gulf Fritillary Caterpillars (because we have alot of those butterflies around here) but wasnt quite sure.

Prominent Caterpillars: Datana species

Dear Heather,
Gulf Fritillary Caterpillars only feed on Passionflower vines.  These are Prominent Moth Caterpillars in the genus
Datana, but the different species in the genus have similar looking caterpillars and there is also much variability within each species with regard to markings and coloration.  The posture they assume, with both head and tail end arched above the middle is typical of Datana caterpillars when they are disturbed.  If we knew what plant they were feeding upon, we might be able to determine the species.  See BugGuide for additional information on the genus Datana.

Prominent Moth
September 2, 2009
Hi bugman–
Since you recently posted a prominent moth caterpillar, I thought you might like this image of an adult (albeit a different species). Using Bugguide, I believe I have identified it as a Sigmoid Prominent Moth, Clostera albosigma.
I found this moth on the wall of an outhouse at Huntington Lake, in the Sierras east of Fresno, CA. The date was mid or early July. Unfortunately, the lighting in the outhouse was not designed for great photography.
This moth was holding very still, and was in the same position two days in a row. I actually thought it was a cocoon. Then on the third day it moved to different wall in the same restroom, and I caught a glimpse of its legs. When I poked it to see if it would move, I found that the knob on the back end of its body is soft, like a brush. I’m wondering if this protrusion acts as a false head to deceive predators.

unidentified caterpillar
Hello What’s That Bug:
Some months ago, I was photographing bugs and stumbled upon two odd looking caterpillars. At first they appeared to be a chrysalis, but they were moving and when I looked closer they were caterpillars. I was wondering if you could identify the caterpillar for me. Here is a link to the picture I took:Thanks in advance for any information,
Michael Thompson

Hi Michael,
Where in the world was the photo taken?

In south Texas near San Antonio…it was just crawling around in my backyard. There were two of them eating on the same plant. I don’t know what the plant was, but it’s some kind of weed, with large, serrated-looking leaves. The caterpillars were about an inch and a half long at most, gray in color, and had humps on their backs which appeared to be tipped with stingers of some sort. The photograph was taken just Northeast of San Antonio Texas in late summer.

Hi again Michael,
This is a Prominent Moth Caterpillar in the genus Schizura, probably Schizura ipomoeae, the Morning Glory Prominent.

Hi Amanda,
This Prominent Moth Caterpillar in the genus
Heterocampa is most likely the White Blotched Heterocampa, Heterocampa umbrata.  You can see many examples on BugGuide of similarly colored purple individuals.  This species, like many caterpillars, changes color right before pupation, and the green camouflage coloration is replaced by this stunning purple and magenta coloration.

Yellow Necked Caterpillar

Dear Dave,
The posture of your caterpillar is a characteristic of the Prominent Moth Caterpillars in the genus Datana.  Your individual looks exactly like this Yellow Necked Caterpillar,
Datana ministra, that is pictured on BugGuide.  According to BugGuide:  “Early instars feed gregariously and skeletonize leaves.  The larvae feed on Malus, Quercus, Betula and Salix species. Young larvae skeletonise the leaves of their host plant. Later, they feed on all of the leaf except the leaf stalk. They feed in groups.”  BugGuide also indicates:  “A common pest in orchards.”  Crabapple is a Malus species.

Dear Daniel Marlos,
Many thanks for the ID and natural history of the yellow necked caterpillar!  We sincerely appreciate you and your group providing this service to us, the general public.  I will share this lep information.

Dear Karen,
We believe that based on this BugGuide image, your Prominent Moth Caterpillar is a White Blotched Heterocampa,
Heterocampa umbrata.  Was there an oak tree near the sighting?  According to BugGuide:  “The larvae feed on oaks (Quercus). Two generations per year in much of range, multiple generations in Florida.”

Yes, there are two oak trees near the spot where he was (one as close as 12-15 ft away).
Thank you so much!

Dear Monarch Mama,
If you compare your caterpillar to this BugGuide image, you should see the similarity to the Prominent Moth Caterpillar,
Heterocampa guttivitta.  We cannot state for certain that the species is the same, but we are confident that the genus Heterocampa is correct.  Was that paper really that pink?  We color corrected it and the green on the caterpillar looks better, but we will delete our color corrected image from the posting if the paper background for the caterpillar was really pink.

Letter 30 – Prominent Moth Caterpillar: Early Instar


I found this little guy on a trail I walk regularly in Gloucester, MA. I am a nature enthusiast with a Bachelor of Science in Biology and have never seen this type of insect before. I am assuming he is a caterpillar because of the feet, but I could be wrong. Please help me solve this mystery. Thanks!
Tara A. Talbot

Hi Tara,
When a caterpillar hatches from an egg, it is termed the first instar. As it grows, it molts and often changes appearance drastically. Most caterpillars go through about 4 or 5 instars. This is one of the early instars of a Prominent Moth, probably the Tentacled Prominent in the genus Cerura. They are also called Puss Moths.

Caterpillar on Cornus
Please help me identify this hitchhiker. I found it on a Cornus mas cutting I took from a friend’s garden. He is oriented facing downward on the twig. In the first photo, you can see two ridges coming from either side of his body and coming together along his back, just above another similar protuberance that is just above his tail. The horn above his head has two red-tipped points. He has a very small, round head that is tucked-in under a hood-like structure above his head. He appears to have three different kinds of feet: the front three pairs are small and pointy. The middle four pairs are fleshy. The last pair, near his tail, are small and stubby. I put the Cornus mas cutting with a potted Cornus nuttallii in case he should need more food, but when I checked on him the next day, he was nowhere to be seen. Can you help me identify him, and what he eats? Thanks

Hi Tammy,
This is a Redwashed Prominent Caterpillar, Oligocentria semirufescens. According to BugGuide, the caterpillar eats a wide variety of leaves, including “Apple, beech, birch, poplar, oak, maples, roses and willows.” Based on your latter, we can add Cornus to the list.

Hi Alley Katt,
Stateside we have an identical caterpillar known as the Tentacled Prominent or Puss Moth, Cerura species. They range over most of North America. It is obviously either a very close relative you have or an introduced species. When disturbed, this caterpillar extends whiplike filaments from each of the two fleshy hornlike projections at the tip of the abdomen and waves these filaments. It can eject an irritating fluid from glands on the thorax.

Linden Prominent Caterpillar

Dear C,
For the most part, native caterpillars are rarely a threat to native plants.  Introduced species like the Gypsy Moth have no natural enemies when they are introduced, which is why exotic imported species often threaten sensitive ecosystems.  We do not recognize your striking Caterpillar, and our initial internet investigation did not produce anything worth citing, so we are posting it as Unidentified and we are hoping our readers help us identify what we suspect is a Noctuoid Caterpillar.

Update:  Thanks to a comment from Cesar Crash, we are confident this is a Linden Prominent Moth Caterpillar, Ellida caniplaga, which is pictured on BugGuideBugGuide notes “The larvae feed on the leaves of basswood (=linden)” and “The larvae are rarely seen (for many years the description of the caterpillar was not known) because they usually feed high in the canopy of basswood trees; they are most likely to be observed descending the trunk of the tree enroute to their pupation site in the soil.”

Thanks so much.  I do have a very tall linden tree nearby and this bug must’ve dropped from the top onto my deck.    Never seen one like it before

Hi again Helen,
We fully appreciate the time investment that goes into identifying the incredibly diverse number of brown moths that can be found in North America, and we often never drill down to the species level when we write back to people, hence many moths on our site are identified only to the family level because that is all that time allows.  Thanks again for the research and the excellent image of
Nadata gibbosa, which according to BugGuide is commonly called the White Dotted Prominent Moth, not the White Spotted Prominent Moth as you have indicated.  BugGuide also states it is called the Green Oak Caterpillar Moth.

  • Greetings Father Sánchez,

    Since my research is limited to the early stages of butterflies (not enough hours in a day to add moths), I can only identify your first photo. It is a caterpillar of the Silverking butterfly, *Archaeoprepona demophoon* (Nymphalidae, Charaxinae), which feeds on several genera in the Lauraceae, its presence on *Piper* a result of wandering. As you discovered, *Heraclides* swallowtail larvae look entirely different and more or less like this:

  • hello, my name is Eileen and i just found your website today and i have to say it is awesome! the reason i even came across your website, is that i had found a beautiful pink caterpillar. now mine looks similar to this one, but not exact. i wish i could take a picture, but i cant right now. i might be able to post one later. it is this shade of pink almost, bit it has hot pink dots the size of a pin head and then theres short little yellow hairs coming out from around the hot pink dots. more scattered, not really clustered. it has a bright yellow ring around its butt. i see 6 black stick like legs in the front and maybe only suction type feet for the rest of his body. there is also a light orange line going down the length of his body with tiny light orange spots right above it also down the length of his body. he also has a gray to black belly. mine doesnt have the same face as the one in this picture. there are no 2 black dots that look like eyes. he’s a rounded face with a orange line tracing his face. what i would like to know is what it is and what they eat. im in cleveland TN and i found him by my porch on the ground in the red dirt, rocks and mulch. there is only a maple tree and pecan tree where i found him, also a little basil plant not very big though at all. also i’d like to know if he will turn into a moth or butterfly? thank you for this awesome website!

    • Hi Eileen,
      Generally, when caterpillars turn pink they are getting ready to pupate. Though we are not certain what you found, it would probably like to bury itself to continue metamorphosis and it is probably not interested in food.

  • I think it is most like Sphingicampa spp. (Saturniidae), but I can’t find a match.

    this is Nadata oregonensis
    Powell and Opler (2009) state Nadata oregonensis is similar to Nadata gibbosa but the forewing has a yellow patch in the discal cell and the postmedian line curves slightly basal at the inner margin. The forewing of N. oregonensis appears more blotchy.

    • Thank you for the assistance with this Prominent Moth in the family Notodontidae. It appears to match the images on BugGuide. We knew it was not Saturniidae because we checked Bill Oehlke’s website with comprehensive species data state by state by country by continent.

  • Pretty cool! The spots and lines on wings reminded me a lot a Sphingicampa. I thought it was wrong too, because there was no similar Sphingicampa on BugGuide.

  • I have a 6 legged (caterpillar) there are no legs mid section or on back section. It is shiny black with brown squares …one square on each side of segment. It looks segmented and the first couple separated segments have white between it. The head is very small…There is no hair no antennas nothing else.

  • Hi,
    I’m Doreen. I live in Ontario Canada. I was cleaning the floor and saw a small pink/skin-coloured caterpillar.

    It was about a half inch long. When I tried to pick it up with a piece of cardboard, it spit a pink gob at the cardboard, then scrunched itself between the floor boards.

    It was smart. I tried to get it to go on the cardboard so I could put it outside. But it squeezed between the cracks of the floor boards and escaped. What is this caterpillar? Or worm? It moved a bit like an inch worm, was hairless. I’ve lived in Canada 53 years, never saw one like that, never had a caterpillar spit at me.

    Two days ago we found a purple and pink caterpillar, and were able to identify it as heterocampa umbrata using this site. Thanks! Upon reading that the bright color was due to it’s being ready to pupate, I put it in a jar with a stick, hoping it would be a great science lesson for my preschool aged kids. Unfortunately I did not realize that these species bury themselves as part of metamorphosis. Our caterpillar crawled under the oak leaves in the jar and covered itself with a sticky/ hard substance. Will it die ,or will we get an awesome view of metamorphosis?
