White Plume Moth

Natural Habitat

Gardens, grasslands, dry marshes, and hedgerows with plenty of low-lying vegetation.

Diet & Feeding

Adults feed on plant nectar; larvae (caterpillars) feed primarily on the leaves of bindweed (Convolvulus) and morning glory.

Behavior Patterns

Chiefly nocturnal but easily disturbed from vegetation during the day. They have a distinctive 'T' shape when at rest, with wings tightly rolled and held at right angles to the body. They are most active from June to August.

Risks & Benefits

Harmless to humans. They provide ecological benefits as pollinators and serve as a food source for birds and bats. The larvae can help control the spread of bindweed, which is often considered an invasive weed.
