Its wings are white with bold black spots and splashes of yellow-orange. The most distinct feature of this moth is the prominent eyespots on its wings, which resemble the eyes of a larger animal.
Habitat
Giant Leopard Moths can be found in a variety of habitats across the United States, including fields, meadows, woodlands, and gardens. They are attracted to light and are frequently seen near porch lights and street lamps at night.
Interesting facts
One interesting fact about the Giant Leopard Moth is that its caterpillars are known as Woolly Bears. Similar to the Isabella Tiger Moth, folklore suggests that the width of the orange-brown band on the Woolly Bear’s body can be used to predict the severity of upcoming winter weather. They are also known for their ability to produce a clicking sound by rubbing together hairs on their bodies, which serves as a warning to potential predators.
Virginian Tiger Moth
Identifying characteristics
The Virginian Tiger Moth is a medium-sized moth with a wingspan ranging from 1 to 1.5 inches. It has a robust and furry body, with striking colors and patterns. The wings are primarily black with distinct white markings, including a white band towards the outer edges.

Interesting facts
An interesting fact about the Virginian Tiger Moth is that the caterpillars, known as Yellow Woolly Bears, have the ability to produce venomous substances that can irritate the skin and cause allergic reactions in some individuals. This venom serves as a defense mechanism against predators. The adult moths, on the other hand, are harmless and do not pose any threat to humans.
Milkweed Tussock Moth
Identifying characteristics
The Milkweed Tussock Moth, also known as the Milkweed Tiger Moth, is a medium-sized moth with a wingspan of about 2 inches. It has a unique and distinctive appearance, with bold black and orange markings on its wings. The caterpillars of this species are easily recognizable with their clusters of black and orange spines.
Habitat
Milkweed Tussock Moths can be found throughout the eastern and central regions of the United States. They are commonly seen in open fields, meadows, and gardens where milkweed plants, their preferred host plants, are abundant. Milkweed plants provide both food and protection for their caterpillars.
Interesting facts
One interesting fact about the Milkweed Tussock Moth is that both the caterpillars and adult moths have toxic properties, making them unpalatable to many predators. This toxicity is acquired from the milkweed plants they feed on as caterpillars. Their bright colors serve as a warning sign to potential predators, indicating their toxicity and discouraging attacks.
Polyphemus Moth
Identifying characteristics
The Polyphemus Moth is a large and impressive moth with a wingspan ranging from 4 to 6 inches, making it one of the largest moths in the United States. It has broad, triangular-shaped wings that are primarily pale yellow with reddish-brown markings. Its hindwings have distinct eyespots, resembling the mythical creature from which it gets its name.

Interesting facts
One fascinating fact about the Polyphemus Moth is its ability to cryopreserve its eggs. In colder climates, the moths lay their eggs on tree branches during winter. The eggs remain dormant until the following spring when the warmer temperatures trigger their hatching. This survival strategy allows the moths to withstand harsh winter conditions and ensure the future generation’s survival.
Banded Tussock Moth
Identifying characteristics
The Banded Tussock Moth is a small to medium-sized moth with a wingspan ranging from 1 to 2 inches. It has a distinct pattern of alternating black and white bands on its wings. The body is covered in long, tufted black and white hairs, giving it a furry and textured appearance.
