You may be curious to know more about the Skiff Moth’s life cycle, habitat, and other characteristics. This article will provide you with valuable information on these aspects, which may not only pique your interest further but also deepen your appreciation for the world of moths and the beauty of nature that surrounds us.

As you continue reading, you’ll uncover fascinating details about the Skiff Moth, including its behavior, role in the ecosystem, and any potential benefits or concerns for humans. By the end of this article, you’ll have a well-rounded understanding of Prolimacodes badia and its significance in our environment.

Distribution and Habitat

North America Spread

The Skiff Moth can be found across North America, with a wide distribution from Florida to Southern Ontario. You may also come across them in Arkansas, Mississippi, and Missouri. Their distribution demonstrates their adaptability to a variety of ecosystems.

Natural Habitat

Skiff Moths mainly inhabit:

  • Deciduous forests
  • Woodlands
  • Nearby agricultural fields

In these habitats, they rely on specific host plants for food and reproduction. For Skiff Moths, these host plants include, but are not limited to, various wild cherry, apple, plum, and hawthorn species. By understanding their distribution and habitat preferences, you can better appreciate the ecological role of this fascinating moth species.


Caterpillar Description

The Skiff Moth caterpillar has a unique appearance. Its body can be various shades of color like green, white, brown, and tan. Interestingly, the caterpillar is hairless, making it smooth to touch. You might also notice its body shape being more oval compared to other caterpillars.

Moth Description

When the Skiff Moth caterpillar transforms into a moth, it exhibits a few distinct features:

  • The wingspan of the Skiff Moth is moderately sized.
  • The color palette of the moth includes shades of brown, tan, and white.

Here’s a comparison table to put the characteristics of the caterpillar and moth side by side:

Caterpillar Moth
Colors Green, White, Brown, Tan Brown, Tan, White
Body Hairless, Oval-shaped Wingspan

So, you can now easily identify both the Skiff Moth caterpillar and moth with the help of these descriptions and comparisons. Just remember to keep an eye out for the unique colors and shapes they possess.

Diet and Predation

Skiff moth caterpillars, known for their distinct appearance, have a specific diet. They primarily feed on the leaves of various trees and shrubs. Here are some examples of their favorites:

  • Blueberry (Vaccinium spp.)
  • Oak (Quercus spp.)
  • Poplar (Populus spp.)
  • Willow (Salix spp.)
  • Birch (Betula spp.)
  • Cherry (Prunus spp.)
  • Chestnut (Castanea spp.)
  • Sweetgale (Myrica gale)

When searching for food, skiff moth caterpillars prefer to munch on leaves that are young and tender. The nutritional value they get from eating these leaves helps them grow and develop into healthy adult moths.

While they enjoy their meals, skiff moth caterpillars also need to watch out for predators. Birds and small mammals, such as rodents, find these caterpillars to be a tasty snack. Some insects, like parasitic wasps, can attack and lay eggs inside the caterpillar’s body.

To protect themselves, skiff moth caterpillars use camouflage to blend in with their surroundings. Their green or brown color helps them hide among the leaves of the trees they call home.

In summary, the diet of skiff moth caterpillars consists mostly of leaves from various tree and shrub species. While they enjoy their leafy meals, they must also be cautious of predators looking for a meal themselves.

Reproduction Cycle

Egg to Larvae

During the breeding season, which typically occurs from May to September, Skiff moths lay their eggs on host plants. The bright green eggs blend in with the plant, making them difficult for predators to find. Once the eggs hatch, the larvae, also known as caterpillars, emerge and begin feeding on the leaves of the host plant. As they consume the plant material, the larvae grow and go through several stages of development, known as instars.

Transformation to Pupa

As the larvae reach the end of their caterpillar stage, they will seek out a suitable location, usually on the host plant, to pupate. This process involves shedding their outer skin one last time and encasing themselves in a protective cocoon. Inside the cocoon, the larvae undergo a remarkable transformation. Their bodies break down into a liquid-like substance before reforming into the structure of an adult moth, a process known as metamorphosis. The pupal stage typically lasts around two weeks.

Emergence as Moth

Once the metamorphosis process is complete, the adult Skiff moth emerges from its pupal case. Adult Skiff moths have a distinct appearance, with cream and brown patterned wings and a wingspan of approximately 35 to 45 millimeters. Now that they are fully-grown moths, their primary focus shifts from consuming plant material to finding a mate and reproducing. Adult Skiff moths are short-lived and generally survive only a few weeks, during which time they mate and lay eggs, completing the reproduction cycle.


The Skiff Moth belongs to the kingdom Animalia, which encompasses a diverse range of living organisms. Within this kingdom, you’ll find the Skiff Moth classified under the phylum Arthropoda, which includes insects, spiders, and crustaceans.

As an insect, the Skiff Moth is a member of the class Insecta, characterized by having three main body parts (head, thorax, and abdomen) and six legs. It belongs to the order Lepidoptera, which consists of butterflies and moths.

The Skiff Moth is part of the family Limacodidae, also known as slug caterpillar moths. This family comprises around 1,000 species noted for their unique slug-like larval stage.

Finally, within the Limacodidae family, the Skiff Moth is classified into the Prolimacodes genus. This genus is home to several species of slug caterpillar moths, including the Skiff Moth.

Here are some key features of the Skiff Moth:

  • Belongs to the kingdom Animalia
  • Part of the phylum Arthropoda
  • Classified under the class Insecta
  • Member of the order Lepidoptera
  • Belongs to the family Limacodidae
  • Classified within the genus Prolimacodes

In summary, the Skiff Moth is an interesting creature classified under the kingdom Animalia, phylum Arthropoda, class Insecta, order Lepidoptera, family Limacodidae, and genus Prolimacodes.

Over the years, our website, has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.

Letter 1 – Probably Skiff Moth Caterpillar


About 8 years ago I found a bug and have yet to identify it. It looked like an egg case. Shaped like a tall pill bug. Pale green in color. It was hard, like a hard rubber. Underneath was orange, soft and sticky. It moved like a slug, but not as fluid. I attached a drawing of it that may be of help. It’s not very complex, but neither was the bug’s appearance. Please help so I can sleep at night.

Hi Derek
I am 99% sure you saw a Skiff Moth Caterpillar, Prolimacodes badia. Here is a photo. We have information on our caterpillar page. Sweet Dreams.

Yup, that’s it. The color’s different, but I just ran into a photo of one that matches the colors in my drawing. THANKS SO MUCH. I feel my life is a bit more complete now. By the way, are those hard to find or something? As I mentioned, I have yet to find another.

They are not rare, but often difficult to find.

ID help
I would like some help with the attached photo. My first thought is its some sort of egg case. I’ve done a lot of searching on the INTERNET and have asked a few knowledgeable friends with no luck. The photo was taken 08/25/2004 in the Charlotte North Carolina area.

Hi Rod,
You don’t have an egg case, but a caterpillar. It is a Skiff Moth, Prolimacodes badia, one of the Slug Caterpillars. There are several color variations of the caterpillar, but this site has a photo that closely resembles yours. The caterpillars which can be found from July through October feed on cherries, oaks, and many other woody plants.

Letter 3 – Skiff Moth Caterpillar


Whats this bug?
A student brought this to me and in my search to find the answer I found the Bugman! The only one who may help me. I’m thinking it is some type of caterpillar. I’d appreciate the help.

Hi Chad,
This is a photographic angle we have never seen on a Skiff Moth Caterpillar, Prolimacodes badia, one of the Slug Caterpillars. The caterpillars which can be found from July through October feed on cherries, oaks, and many other woody plants.

Letter 4 – Skiff Moth Caterpillar


Pupa in leaf cocoon
September 19, 2009
Saw this on the stalk of a sapling at Wallops Park in Accomack County on the Eastern Shore of VA on Sept. 19, ’09. It’s about the size of a periwinkle (1-1.5″). When I brushed the plant and it fell off, it clamped on to a pine shat. I guess it’s a caterpillar of some kind that makes its cocoon out of leaves, but haven’t been able to make a specific ID. I’ve been walking this trail almost every day for the past 17 years, and have never seen anything like it. Any info you can offer would be appreciated. Thanks.

Skiff Moth Caterpillar

Dear Liz,
This is a Skiff Moth Caterpillar,
Prolimacodes badia, and it is pictured on BugGuide where it states:  “Larvae feed on leaves of wide variety of trees and shrubs, including birch, blueberry, cherry, chestnut, Hophornbeam (Ostrya virginiana), oak, poplar, Sweetgale (Myrica gale), willow, and others.”

Your letter to the bugman:  This was on my boat cover this summer which was parked under some walnut trees. Please help identify.
How you want your letter signed:  Ben

Skiff Moth Caterpillar

Dear Ben,
You have the Slug Moth Caterpillar Limacodidae correct.  This is a Skiff Moth Caterpillar,
Prolimacodes badia, and here is a BugGuide image for comparison.  Your individual has much larger tubercles that those on most pictured specimens.  According to BugGuide:  “larvae feed on leaves of wide variety of trees and shrubs, including birch, blueberry, cherry, chestnut, Hophornbeam (Ostrya virginiana), oak, poplar, Sweetgale (Myrica gale), willow, and others” so we suppose “others” can include walnut.

Letter 7 – Skiff Moth Caterpillar, maybe


found weird bug!
Hi there…
i wish i has a digital camera to take a pic, but i don’t… hope my bitmap drawing helps a bit. this thing doesn’t seem to have legs on its flat bottom….it’s about 3/16″ long….it looks like a piece of a twig or something…. but it seems to have an eye right in the middle of the ‘head’ and the yellowish thing on the front seems to be moving around like some kind of antennae.
any clues?

One can never be sure with a drawing, but you have a rather abstract likeness to a Skiff Moth Caterpillar.

Green, leaf-eating, slug-like insect
September 18, 2009
I found these two legless, hard-bodied slug-like insects eating my ornamental plum tree leaves. As you can see, the one on the right is shedding its skin. They look like little horseshoe crabs. I’ve never seen anything like them!

Hi Holly,
We doubt that these Skiff Moth Caterpillars, Prolimacodes badia, will ever be plentiful enough to damage your ornamental plum since they are small caterpillars and they will never be able to defoliate the tree.  Many members of this family, Limacodidae, have caterpillars with stinging spines, but the Skiff Moth Caterpillar is not one of those, so it is perfectly harmless.

Thanks, Daniel. These guys had me really baffled! I thought they might be some sort of exotic species. I’m not worried about my tree – there’s plenty to go around!
Thanks again,

Skiff Moth

Dear Storm,
While we don’t recognize this moth, we agree that it is quite lovely, and with National Moth Week fast approaching, we are trying to post as many interesting moth photos as possible.  Alas, we are beginning to get computer fatigue, so we are posting your photo as unidentified in the hopes that one of our readers can assist with the identification.  Karl, are you there????

Update:  Thanks to CTGirl who sent in a comment, we can report that this is a Skiff Moth, one of the Slug Caterpillar Moths which we verified on BugGuide.

  • i saw one of these squeeze out of a tiny hole in an acorn. i wonder where they lay their eggs?

  • Maybe a Skiff Moth? Prolimacodes badia

    • Dear CTGirl,
      Thanks for the assistance. We have seen and identified the Caterpillars numerous times, but we did not recognize the moth.

  • I’ve found one of these in central Indiana about this time last year, took a good picture of it and tossed it since I couldn’t identify it!!

  • I recently purchased a house with two purple flowering plum trees in the back yard. Mysteriously, both have been suffering pretty bad defoliation. I finally found two of these suckers on one tree. Bringing one inside in a container, I witnessed it demolish a single leaf rather quickly. Could this be the only culprit for the defoliation?
