White-lined Sphinx Moth

Natural Habitat

Widely distributed across North and Central America in environments ranging from deserts and grasslands to gardens and forests.

Diet & Feeding

Adults feed on flower nectar from various plants (like four o'clocks and honeysuckle) using a long proboscis; larvae (caterpillars) eat leaves of plants like willowweed and evening primrose.

Behavior Patterns

Known for hovering while feeding, which causes them to be mistaken for hummingbirds. They are crepuscular (active at dusk and dawn) but are also frequently seen during the day.

Risks & Benefits

They are essential pollinators for many native plants and garden flowers. While the caterpillars may graze on garden plants, they are rarely considered significant pests and are generally harmless to humans.
