Learn essential facts about garden moths and how to identify them. Plus, see photos of some beautiful garden moths you might find.
Garden Moths You Should Know
When it comes to an insect popularity contest between butterflies and moths, butterflies get most of the attention. Butterflies are usually, but not always, larger and more colorful. Plus, most moth species, such as the luna moth, fly at night when we’re not as likely to see them. This isn’t a reason to ignore garden moths, though. Some are important pollinators, and all are a food source for birds and other wildlife you want to attract.
You can find thousands of moth species in North America, but we wanted to highlight a few of the most impressive ones. To attract them, plant their caterpillar host plants and make sure you never spray pesticides. You don’t want to harm the helpful bugs in your yard.
This large, widespread garden moth has a wingspan of more than 4 inches. Males have pale yellow forewings and females have a reddish brown. Both have a striking “eyespot” on each hind wing, which helps deter predators. Host plants include hackberry, willow, mesquite, redbud, currant and blackberry.

Scarlet-Bodied Wasp Moth
This gorgeous garden moth has a bright red body with black-lined, clear wings. You might have trouble believing it’s a moth because it looks more like a wasp. This mimicry behavior helps keep predators at bay. It’s found in coastal areas from South Carolina through Florida and across the Gulf Coast into Texas. Hemp vine is its caterpillar host plant.

These medium-sized garden moths are a pretty pale yellow, and females have orange hind wings. Common across the continent, you’re most likely to encounter this garden tiger moth species in its caterpillar phase when it’s known as a woolly bear. These furry, reddish brown and black-banded caterpillars are often spotted on the move in the fall. They spend winter as full-grown caterpillars, and are specially adapted to survive freezing temperatures.
Isabella tiger moths emerge as adult moths in the spring. Attract them with host plants such as asters, birches, maples and elms, and by leaving fallen leaves in your garden.
