Adult Markings: A dark, heavily streaked sphinx moth. A black triangular patch at the base of the hindwing and two well-developed bands on the hindwing distinguish this species; photographs should show a portion of the hindwings should be sufficient to separate this species from Paratrea and other species with heavy markings and a pale discal spot on the forewings. Sexes are similar. |
Wingspan: 6.5 - 7.5 cm (Covell, 1984) |
Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: The larva has a peculiar dorsal protuberance on the second thoracic segment in early instars which disappears in the fifth larval stage and is replaced by a diagnostic hump. This transformation unites the members of the genus and all 5 species in the U.S. feed on mints. A large, dark eyespot is also typically found on the dorsal surface of the thorax (Wagner, 2005). |
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants. |
