The White-lined Sphinx (Hyles lineata) is a common sphinx or hawkmoth that ranges from Central America north through Mexico and the West Indies to most of the United States and southern Canada. It also occurs in Eurasia and Africa. Both the adult and caterpillars feed on a wide variety of sources. Adults usually fly at dusk, during the night, and at dawn, but they will also fly during the day. Wingspan averages around three inches (7.5 cm).
