Banded sphinx moth caterpillar (likely)

Moist, vegetated habitats such as stream edges, gardens, woodland margins, and wetlands. Caterpillars often rest on soil, rocks, or pavement while seeking pupation sites.

Larvae chew leaves, especially plants in the evening primrose family (Onagraceae), including willowherb and evening primrose. Adults feed on nectar from flowers.

Mostly nocturnal; larvae may hide during the day and wander to pupate underground or beneath debris. Several generations can occur in warm climates.

Harmless to people and nonvenomous; it does not sting. It is a native pollinator as an adult and a food source for birds and other predators, though larvae can occasionally defoliate host plants.
