What is the Asp Caterpillar?
The asp caterpillar, scientifically named Megalopyge opercularis, is a venomous caterpillar found mainly in the southern United States, Mexico, and parts of Central America. It belongs to the family Megalopygidae, which comprises a variety of moth species. This caterpillar is the larval stage of the southern flannel moth, known for its beautiful golden-yellow wings as an adult.
Despite its small size—usually growing up to 1 inch in length—the asp caterpillar is infamous for its potent venom. Its hairy appearance resembles a tuft of cotton or fur, making it easy to mistake for a harmless object. However, those hairs conceal venomous spines that can cause severe pain upon contact. The caterpillar’s venom is a defense mechanism against predators, but it often ends up stinging humans who accidentally touch or handle it.
Key Facts About the Asp Caterpillar
- Scientific Name: Megalopyge opercularis
- Family: Megalopygidae
- Size: Approximately 1 inch in length

Physical Characteristics and Appearance
The asp caterpillar is easily recognizable due to its distinctive, fluffy appearance. Its body is covered in dense, soft hairs that range in color from light gray to golden brown, giving it a plush, velvety texture. This unique look has led to its nickname, the "puss caterpillar," as it resembles a tiny Persian cat.
However, the hairs are not just for show. Beneath the soft exterior lie venomous spines that can cause severe pain and medical complications. These spines are connected to venom glands, which inject venom when they come into contact with skin. The hairs act as a defense mechanism, deterring predators while disguising the caterpillar’s true nature.
How to Identify an Asp Caterpillar?
Here are some key features to help you identify an asp caterpillar:
- Length: About 1 inch (2.5 cm)
- Color: Light gray, golden brown, or even orange
- Texture: Dense, fluffy hairs that resemble fur
- Shape: Oval and slightly tapered at the ends
It’s important to note that the caterpillar’s appearance can vary depending on its stage in the life cycle and environmental factors. Always exercise caution when dealing with unknown insects, especially those with a furry or spiny appearance.
Where Do Asp Caterpillars Live?
The asp caterpillar is commonly found in regions with warm, humid climates. Its primary habitat includes the southern United States, particularly in states like Texas, Florida, and Louisiana. It can also be found in Mexico and parts of Central America, where similar environmental conditions prevail.
The caterpillar prefers to reside in areas rich in vegetation, such as:
- Ornamental shrubs
- Shade trees like oak, elm, and sycamore
- Garden plants
- Residential areas with dense greenery
Because of its habitat preferences, the asp caterpillar is often encountered in parks, gardens, and residential neighborhoods. Homeowners should be especially cautious during the caterpillar’s active seasons—spring and fall—when it is most likely to be found on trees, fences, and outdoor furniture.
What Do Asp Caterpillars Eat?
Like most caterpillars, the asp caterpillar is herbivorous, feeding primarily on the leaves of trees and shrubs. Its diet includes a wide variety of plant species, but it shows a particular preference for:
- Oak trees
- Elm trees
- Sycamore trees
- Ornamental plants like roses and boxwoods
- Fruits and flowering plants
By consuming leaves, the asp caterpillar plays a role in the ecosystem by contributing to the natural pruning of trees and shrubs. However, large infestations can cause significant damage to plants, leading to defoliation and weakened vegetation. Gardeners should be vigilant about controlling caterpillar populations to prevent excessive damage.
In the following sections, we’ll explore the life cycle, dangers, and precautions associated with the asp caterpillar. Stay tuned to learn how to protect yourself and others from this venomous yet fascinating insect.
