Most Hummingbird Hawk-moths fly at might and are rarely seen. A few species fly during cloudy afternoons and at dusk when they feed at flowers in a manner similar to that of a hummingbird. Hummingbird Moths use a long, thin, needle-like mouthpart called a proboscis to eat. The proboscis stays coiled up like a garden hose until it is time to use it. When the moth approaches a flower, it uncoils its proboscis and dips it deep into the flower where the nectar is. The moths in these images are White-linned Sphinx Moths which came out just before dusk in Prescott, Arizona.
