Natural Habitat

Grassy areas, lawns, meadows, and agricultural fields where grass provides ample cover and food.

Diet & Feeding

Larvae (webworms) feed on the base and blades of grass and turf. Adults primarily feed on flower nectar.

Behavior Patterns

Adults are nocturnal and are highly attracted to lights at night. During the day, they rest on grass stems or walls in a characteristic head-downwards, wing-rolled position that makes them look like tube-shaped debris.

Risks & Benefits

The larvae can be significant pests for lawns and golf courses by causing brown patches. Adults are harmless to humans and serve as a food source for birds and bats.
