Sod Webworm Moth

Lawns, grassy fields, pastures, and meadows throughout North America.

Adults primarily feed on flower nectar; larvae (webworms) feed on the leaves and stems of various turfgrasses.

Adults are nocturnal and are frequently seen flying low over lawns at dusk. They have a characteristic habit of rolling their wings tightly around their bodies when at rest. Larvae live in silk-lined tunnels in the soil or thatch.

Larvae can be significant pests of ornamental lawns and golf courses by causing brown patches. They serve as an important food source for birds and predatory insects.
