Field Guide Descriptions: Covell (1984) | 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: Fore-wings are marked with light brown costal and outer margins, a paler y-shaped stripe that divides the median area into a three dark zones, and a series of narrow light lines running from the costa to the inner margin; hindwings are pinkish or crimson along the outer and inner margins. Eumorpha vitis is very similar but lacks the tan stripe along the costa. Hyles lineata is also similar but has only a single pale line running through the center of the wing and has a wider band of pink on the hindwing. Sexes are similar. |
Wingspan: 8.7 - 9.6 cm (Covell, 1984) |
Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: Larvae have multiple phenotypes, including a green form and one that is brilliantly marked with red and black stripes in addition to the usual pale lateral stripes; a caudal horn is lacking (see Wagner, 2005, for two examples). Pupation occurs underground. |
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants. |
