This large sphinx is unusual for several reasons. It is one of the few species of the genus Sphinx that shows significant sexual dimorphism. Also, the males in particular are apparently mainly diurnal and have been collected while nectaring at flowers, including lilacs and dandelion. Females appear to be active in the evening and at night, and have been collected only at lights. Clemens' Sphinx have also been observed visiting and apparently obtaining nourishment from dead, decaying fish, and this behavior has been observed along the North Saskatchewan River here in Alberta.
Conservation Conservation: Although widespread, it appears to be very uncommon. Diet Info
No Alberta ata. Elsewhere reported to use a variety of trees and shrubs as larval hosts, including apple, ash, birch, northern bayberry, poplar, wax-myrtle, willow, and others (McGuggan, 1958; Covell, 1984; Handfield, 1999).

Range Widespread in eastern North America, from the maritimes west to central Alberta. In Alberta it has been found along the southern edge of the boreal forest and in the aspen parkland region.
