Ghost Moth

Natural Habitat

Grassy meadows, pastures, and disturbed urban areas where host plants such as grass roots, dock, and nettles are present.

Diet & Feeding

Larvae (caterpillars) feed underground on the roots of various grasses and wild plants; adults do not feed and live only long enough to mate.

Behavior Patterns

They exhibit a unique 'hovering' flight pattern during dusk; males often congregate in leks to attract females with their bright white wings. They have a lifecycle that can last up to two years as larvae.

Risks & Benefits

Generally harmless to humans and not considered a major agricultural pest, though larvae can occasionally damage crop roots. They serve as a food source for bats and birds, contributing to local biodiversity.
