Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012) | Online Photographs: MPG, BugGuide, GBIF, BOLD | Technical Description, Adults: Forbes (1948); Hodges (1971); Tuttle (2007) | Technical Description, Immature Stages: Forbes (1948); Wagner (2005); Tuttle (2007) | |
Adult Markings: The typically dark forewings and lemon color on the hindwings around the ocellus distinguish this species from Smerinthus species and Paonias excaecata. Some forms are more yellowish, resembling Paonias astylus, but are more mottled and have a more waved outer margin on the forewing. Sexes are similar. |
Wingspan: 4.5 - 7.5 cm (Covell, 1984) |
Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: Larvae resemble those of other members of this genus: green with pale oblique stripes on the sides, the last one most prominent and extending to the base of the caudal horn; body granulate (see Wagner, 2005, for details). Pupation occurs underground. |
