It is found in Nova Scotia, New Brunswick and Prince Edward Island, and across the rest of Canada all the way to British Columbia. In the United States it ranges south to Florida in the east, and westward to eastern California and as far south as central Texas.
The eggs are greenish yellow and small. Hornworms hatch after about 8 days. Primary food sources for the larvae are deciduous trees such as willows, birch and cherries, as well as shrubberies, like ninebark and roses. Like the rest of the family Sphingidae, they burrow shallowly into soil to pupate. Once they leave their pupa, the adults almost immediately mate. Adults do not feed.
