With their bright colors and prickly exterior, these caterpillars might catch your attention, but they’re not nearly as harmful as other well-known caterpillars, like the venomous gypsy moth. Although they’re not poisonous, the red humped caterpillar may cause mild skin irritation if they come into contact with human skin. Furthermore, these caterpillars are not known to cause any significant plant damage, so if you come across them in your garden, don’t be too quick to get rid of them.

So, the next time you see these critters in the great outdoors, you can enjoy their lively appearance without worrying too much about their potential danger.
Physical Description of Red Humped Caterpillars
The red humped caterpillar (Schizura concinna) is a common species found in the eastern part of North America. This caterpillar gets its name from the red hump on the eighth segment of its body. The caterpillar is generally green in color with a darker shade of green on its back and a lighter shade on its sides. Its body is covered with small hairs or setae that can cause skin irritation if touched.
- The caterpillar measures about 1-2 inches in length
- It has a distinct red hump on the eighth segment of its body
- The body is generally green in color with a darker shade on its back and lighter shade on its sides
- The caterpillar is covered with small hairs or setae that can cause skin irritation if touched
The red humped caterpillar goes through five instars or growth stages before turning into a pupa and eventually a moth. During its final instar, the caterpillar changes its color to a brownish-yellow and develops a series of black and white bands. The caterpillar then spins a cocoon and undergoes metamorphosis, emerging as a brownish-gray moth with a wingspan of about 1.5 inches.
The red humped caterpillar can be found on a variety of trees and plants, including oak, maple and apple trees. The caterpillar feeds on leaves, often consuming the entire leaf except for the midrib. While they can cause damage to plants, they are not considered to be a serious pest and are generally not harmful to humans or animals.
| Physical Characteristics | Behavior | Eating Habits |
|---|---|---|
| 1-2 inches in length | Feeds on leaves, often consuming the entire leaf | Found on a variety of trees and plants |
| Green in color with a darker shade on its back and lighter shade on its sides | Goes through five instars before turning into a pupa and eventually a moth | Not considered to be a serious pest |
| Covered with small hairs or setae that can cause skin irritation if touched | Spins a cocoon and undergoes metamorphosis to become a moth | Generally not harmful to humans or animals |
Poisonous Caterpillars
Caterpillars are widespread insects, and they are the larvae of butterflies and moths. Most of them are harmless and even beneficial for the environment, but some species are poisonous and can cause severe damage to human health. The poisonous caterpillars possess urticating (irritating) hairs, spines, or glands on their body containing venom that can cause various allergic reactions.
- Io Moth Caterpillar: These caterpillars are green in color and have a distinct white-and-black line on their sides. They are incredibly venomous, and their sting can cause symptoms like swelling, itching, and redness on the affected area.
- Saddleback Caterpillar: These caterpillars have a bright green, saddle-shaped patch on their back, which makes them distinguishable. They have numerous spines on their body that contain venom and can cause severe allergic reactions.
- Stinging Rose Caterpillar: This caterpillar has several branched spines and venomous hairs on its body. Their sting can cause severe pain and itching, which can last for hours or even days.
One of the commonly found caterpillars is the red humped caterpillar. They are medium-sized caterpillars that have a distinctive red hump on their body. Red humped caterpillars belong to the family of sphinx moth caterpillars. They are not considered poisonous. They lack urticating hairs, spines, or venom glands, making them safe to handle.
It is essential to remember that caterpillars can be dangerous, and it is always better to avoid direct contact with them. In case of accidental contact, it is advisable to wash the affected area with soap and water and apply a cooling ice pack. If the symptoms persist or worsen, seek medical attention immediately.
Below is a table that summarizes some of the poisonous caterpillars:
| Caterpillar | Appearance | Effects of Sting |
|---|---|---|
| Io Moth Caterpillar | Green with a white and black line on the side | Swelling, itching, and redness on the affected area |
| Saddleback Caterpillar | Bright green with a saddle-shaped patch on the back | Severe allergic reactions |
| Stinging Rose Caterpillar | Branched spines and venomous hairs on the body | Severe pain and itching |
It is crucial to be cautious around caterpillars, as some of them can lead to severe health issues. Always consult a medical professional if you experience any abnormal reactions after coming in contact with a caterpillar.

- Symptomatic treatment may include antihistamines, pain relievers, and/or topical corticosteroid creams to manage skin irritation and itching.
In rare cases of severe allergic reaction, emergency medical treatment such as epinephrine injections may be necessary to prevent serious complications.
If you have a history of severe allergic reactions or asthma, it is important to take extra precautions to avoid contact with red humped caterpillars and other venomous insects. Wear protective clothing when gardening or spending time outdoors, and be sure to seek prompt medical attention if you experience any symptoms of an allergic reaction.

Prevention of Red Humped Caterpillar Infestation
The Red Humped Caterpillar is a common pest that often feeds on various broadleaf trees and shrubs, such as oak, walnut, and elm. These caterpillars may appear harmless, but they can be quite destructive to foliage. The good news is that you can prevent these caterpillars from infesting your plants and causing damage. Here are some ways to prevent red humped caterpillar infestation:
- Plant Resistant Trees and Shrubs: One of the most effective ways to prevent red humped caterpillars is to plant trees and shrubs that are resistant to them. Some examples of resistant plants include holly, dogwood, and cypress.
- Remove Caterpillar Eggs: Red humped caterpillars lay their eggs in clusters on the undersides of leaves. Look for these clusters and remove them as soon as you spot them. This will prevent the caterpillars from hatching and infesting your plants.
- Prune Infested Branches: If you notice infested branches, prune them immediately and dispose of them far away from your garden. This will prevent the caterpillars from spreading to other areas.
In addition to these preventative measures, there are also some natural ways to deter red humped caterpillars from your garden:
- Natural Repellents: Planting natural repellents such as lavender, mint, and chives around your garden can deter caterpillars. These plants produce strong scents that interfere with the caterpillar’s ability to find food.
- Bird Feeders: Encourage birds to visit your garden by placing bird feeders. Birds love to feast on caterpillars and can help keep their population under control.
- Beneficial Insects: Introduce beneficial insects into your garden, such as ladybugs and lacewings. These insects feed on caterpillars and can help to reduce their population in a natural way.
By following these preventative measures, you can keep your garden free from red humped caterpillar infestation. However, if the infestation becomes too severe, it may be necessary to use pesticides. Consult with a professional before using any pesticides to ensure that they are effective and safe to use around your plants.
| Preventative Measure | Effectiveness | Safety |
|---|---|---|
| Plant Resistant Trees and Shrubs | High | Safe |
| Remove Caterpillar Eggs | High | Safe |
| Prune Infested Branches | Medium | Safe |
| Natural Repellents | Low | Safe |
| Bird Feeders | Medium | Safe |
| Beneficial Insects | Medium | Safe |
| Pesticides | High | Use with Caution |
Remember to take a proactive approach to controlling red humped caterpillar infestation in your garden. The key is to start early and use a combination of preventative measures to keep these pests under control.
Natural Methods for Reducing Red Humped Caterpillars Population
