What Are Tussock Caterpillar Moths?

Tussock Caterpillar Moths are a group of insects belonging to the family Erebidae. They get their name from the tufts or “tussocks” of hair-like projections on their bodies, which give them a distinctive appearance. These moths undergo a fascinating metamorphosis, starting as tiny eggs, then hatching into caterpillars before finally transforming into moths.


When you come across a Tussock Caterpillar Moth, you might notice its colorful and hairy caterpillar stage. These caterpillars can vary in appearance, but they often have vibrant colors such as black, white, orange, or yellow. They later grow into White Marked Tussock Moths, Fir Tussock Moths, or another species of the tussock moth orgyia. You can check out the University of Florida page about Tussock Caterpillar Moths to learn about these creatures.

Some species also have distinct markings or tufts of hair along their bodies. Tussock Caterpillar Moths are often mistaken for Puss Caterpillars. Puss Caterpillars can also be found in North America and Florida, as well as most of the southwest United States.

Where Are They Found?

Tussock Caterpillar Moths inhabit various habitats around the world, including forests, grasslands, and gardens. They enjoy living on host plants in gardens. They are most active during the warmer months and they often seek out areas with plenty of vegetation. Their egg laying begins in the end of March and early April.

Tussock Caterpillar Moths often crawl on oak trees. Be cautious when walking outside, as caterpillars may fall from trees onto you. Many people have reported this happening.

The Life Cycle of a Tussock Caterpillar Moth

The life cycle of a Tussock Caterpillar Moth begins with the adult female laying eggs on the leaves of plants. These eggs hatch into tiny caterpillars, which immediately start feeding on the surrounding vegetation.

As they grow into mature larvae, the caterpillars molt several times. This means they are shedding their old skins to accommodate their increasing size. During this stage, they are voracious eaters, the young larvae feed on large amounts of plant material to fuel their growth.

After eating a lot, caterpillars go into a cocoon and change into moths when they are full grown. After a period of development, the pupae emerge as adult moths. The adults emerge into mating and continue the cycle anew. This remarkable journey from egg to moth showcases the intricate and fascinating life cycle of the Tussock Caterpillar Moth.

Negative Effects on Homes and Gardens

While Tussock Caterpillar Moths may seem harmless, they can actually cause damage to plants in gardens and invade homes. The caterpillars feed voraciously on leaves, which can defoliate plants and weaken them. In some cases, infestations of Tussock Caterpillar Moths can lead to significant damage to crops and ornamental plants.

Stings and Symptoms

One thing to be cautious about when dealing with Tussock Caterpillar Moths is their stinging hairs and venom glands. These hairs contain irritating substances that can cause skin irritation, itching, and sometimes even allergic reactions in sensitive individuals. If you touch the hairs of a Tussock Caterpillar Moth, wash the area with soap and water. After washing, apply cream or antihistamine to help alleviate any discomfort.

Cellophane tape is also helpful when you make contact with a Tussock Caterpillar Moth. Apply the tape over the area where you were stung to remove the small venomous hairs that stick to your body. Victims of a “poke” have also reported that mustard on the affected area can help.

Prevention and Control

To prevent Tussock Caterpillar Moths from becoming a nuisance in your home or garden, there are several measures you can take:

Maintain a Clean Garden: Keep your garden free of debris and weeds, as these can provide hiding spots for caterpillars.

Prune Infested Plants: If you notice signs of infestation, such as chewed leaves or caterpillars, you should prune affected branches or plants to prevent the spread of the insects.

Natural Predators: Encourage natural predators of Tussock Caterpillar Moths, such as birds and parasitic wasps, by providing habitat and food sources in your garden.

Insecticides: You can use insecticides labeled for caterpillar control, but be sure to follow the instructions carefully and use them sparingly to minimize harm to beneficial insects and the environment.


Tussock Caterpillar Moths may be small, but they can have a big impact on your home and garden if left unchecked.
