The paddle caterpillar, also known as the saddleback caterpillar, is a fascinating creature found in various parts of the United States. As the larval stage of the limacodid or slug moth (Acharia stimulea), this inch-long caterpillar is easily recognizable by its bright green color and distinctive brownish-purple spot in the middle of its back, reminiscent of a saddle for pack animals 1.
Not only does the saddleback caterpillar have a unique appearance, but it also has defensive mechanisms that set it apart from many other caterpillars. The spines that cover its body can release venom upon contact, which can cause pain, itching, and in some cases, more severe reactions. To protect yourself, it’s important to learn how to identify the saddleback caterpillar and exercise caution when near them.
In this article, you’ll learn about the saddleback caterpillar’s life cycle, its preferred habitats, and the signs of contact with its venomous spines. You’ll also gain insight into how these fascinating creatures contribute to their ecosystem. So, let’s dive in and discover all there is to know about paddle caterpillars!
Paddle Caterpillar Overview
Species and Varieties
Paddle caterpillars are not actually a specific species of caterpillar, but a possible misinterpretation of similar-looking insects. Two known caterpillars that share similar characteristics are the Asp Caterpillar and the Packsaddle Caterpillar:
| Asp Caterpillar | Packsaddle Caterpillar |
|---|---|
| Known as the Puss Caterpillar or Southern Flannel Moth | Also known as the Saddleback |
| Small and hairy | Bright green with a brownish-purple spot on its back |
Distinctive Features
- Asp Caterpillars are small and hairy, with a distinctive tuft of fur-like spines on their back.
- Packsaddle Caterpillars have a saddle-like brownish-purple spot on their back, providing its unique appearance.
These distinctive features make these caterpillars interesting to look at and easier to identify. Remember to enjoy their beauty from a safe distance, as some may have stinging hairs or spines that can cause irritation.
Habitat and Distribution
Geographical Range
The Paddle Caterpillar, also known as the Saddleback Caterpillar, can be found throughout eastern North America, from Georgia to Illinois1. Their range includes:
- Georgia
- Illinois
- Other parts of eastern North America
Finding Paddle Caterpillars in the Wild
To find Paddle Caterpillars in the wild, look for them on various host plants, such as:
- Oaks
- Sweet gum
- Basswood
- Cherry
Pros and cons of searching for Paddle Caterpillars in the wild:
| Pros | Cons |
|---|---|
| Educational | Stinging hairs |
| Appreciation for nature | Hard to locate |
Be cautious when approaching, as their stinging hairs can cause irritation. Remember to respect their habitat and maintain a friendly distance.
Life Cycle and Behavior
Larval Stage
The saddleback caterpillar, also known as the packsaddle caterpillar, is a bright green larva with a brownish-purple spot in the middle of its back. During this stage, it is about 1 inch long and has urticating hairs located on knobs at the front and rear, as well as smaller knobs on the sides. Their primary job at this stage is to feed on various types of leaves.
Some key features of the larval stage include:
- Bright green color
- Urticating hairs on knobs
- Brownish-purple spot resembling a saddle
Examples of their preferred food include oak, dogwood, and plum tree leaves.
Adult Stage
Once mature, the saddleback caterpillar transforms into a moth, which has a glossy dark brown color with a single white dot near the forewing base. The moths have dense scales giving them a furry appearance, and females are typically larger than males with a wingspan ranging from 26-43 mm (1.0-1.7 inches).
Some characteristics of the adult stage include:
- Glossy dark brown color
- Furry appearance due to dense scales
- Wingspan 26-43 mm, with females larger than males
| Comparison | Larval Stage | Adult Stage |
|---|---|---|
| Color | Bright green with brownish-purple spot | Glossy dark brown |
| Size | Approximately 1 inch long | Wingspan: 26-43 mm (1.0-1.7 inches) |
| Key Features | Urticating hairs, saddle-like spot | Furry appearance, white dot on forewing |
Both the larval and adult stages are important in the life cycle of these fascinating creatures, and understanding their unique characteristics can help to better appreciate their role in nature.
Safety Tips and Irritation
Stinging Spines and Venom
The Packsaddle caterpillar, also known as saddleback, has spines on its back that can cause pain and irritation. Here are some tips for dealing with these outdoors:
- Be cautious around them and avoid direct contact
- Wear gloves and protective clothing while gardening
When accidentally touched, the spines may release venom, leading to:
- Intense pain
- Redness and swelling
- Itching and burning sensations
Handling and Treatment
If you come into contact with a Packsaddle caterpillar, take these steps for safe handling and treatment:
- Gently remove the spines using tape or tweezers
- Wash the affected area with soap and water
- Apply a cold compress to reduce swelling
For pain and irritation relief, consider using:
- Over-the-counter painkillers
- Antihistamine creams or oral medication
- Hydrocortisone cream
Remember, it’s essential to avoid direct contact with these caterpillars and seek medical attention if symptoms worsen.

I just saw one of these caterpillars on a pin oak in Brazil, IN!!!
I just found one in Kent Ohio found what is was on this website
I just found one yesterday on an Azalea at a greenhouse I work at in Central Wisconsin! It took me awhile to find out what type it was. Then I read it was very uncommon to see here so I went back today to try and look for it again, and there is was, the same spot I first saw it yesterday!
One found in northeast Ohio!
I photographed a paddle caterpillar in Olmsted Twp., Ohio, on September 11, 2017. I almost didn’t stop to look and see what it was. Luckily, I took two photos. Haven’t seen it since. I understand that the paddle caterpillar is a fairly rare sighting.
Found one a couple of days ago in southwest Michigan.
Just found one in Medford, OR!
One found in southwest Missouri this week. I took photos too.
I know this is a really old article, but we just saw one of these in Northeast Kansas. I had a difficult time finding out what it was online, most images showed an Alder moth caterpillar, which looks similar, but not what we had. I snapped a picture because it was pretty and I’ve never seen one like it before.
