Explanation of Names
described by Clemens in 1859
Numbers
Sixteen Sphinx species occur in America north of Mexico.
Size
wingspan 56-80 mm (U. of Alberta); female larger than male
Identification
Adult: forewing mostly yellowish-gray in male; pale gray with slight yellow tint in female; black shading beyond PM line widens toward inner margin in both sexes; hindwing deep yellow in male, pale yellow in female; outer border black, broad in both sexes (1)
one of the few species of Sphinx that shows significant sexual dimorphism

Larva: body bright green with several red and whitish diagonal dashes along side; horn on last abdominal segment; skin grainy/rough in fourth instar, smooth in final (fifth) instar
Range
Yukon and Alberta to Nova Scotia, south to New Jersey, west to Utah and Montana (may have occurred south "to the Carolinas" as stated below by Holland more than 100 years ago, but the species name does not appear on current lists from South Carolina, North Carolina, or Maryland, and probably doesn't occur in these areas today)
Holland's The Moth Book (1903) says "The insect occurs from Canada to the Carolinas, and westward through the eastern portion of the valley of the Mississippi." (2)
Habitat
clearings, edges and meadows in wooded areas
males are mainly diurnal and have been collected while nectaring at flowers; females are active in the evening and at night, and have been collected only at lights
Season
adults fly in June and July (1)
Food
larvae feed on leaves of apple, ash, northern bayberry, birch, poplar, wax myrtle, willow, and other plants
Holland states "The caterpillar feeds upon various species of willow." (2)
adults take nectar from flowers such as dandelion, lilac, and Russian-olive, and have been reported on multiple occasions feeding on decaying fish
Life Cycle
one generation per year; overwinters as a pupa in underground cell
Larva (new-born); Larva (pre-pupal):
Remarks
Global Rank: G3 - Very rare or local throughout its range, or found locally in a restricted range (21 to 100 occurrences). Threatened throughout its range.
