White-lined sphinx moth (striped hawkmoth)

Open habitats including gardens, grasslands, deserts, woodland edges, and urban areas across much of North America.

Adults drink nectar from flowers, often hovering like hummingbirds; caterpillars eat foliage from many plants, including evening primrose, willowherb, grape, and tomato relatives.

Primarily nocturnal but active by day; strong, fast fliers attracted to lights. Females lay eggs on host plants, and larvae can occur in large, periodically migratory groups.

Harmless to people and nonvenomous; caterpillars may occasionally defoliate garden plants. Adults are important pollinators, and larvae provide food for birds and other predators.
