Field Guide Descriptions: Covell (1984) | Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD | Technical Description, Adults: Sargent (1976); Schweitzer et al. (2011) | Technical Description, Immature Stages: Schweitzer et al. (2011); Wagner et al. (2011) | |
| Adult Markings: A medium-sized Catocala, with blue-gray to dark gray forewings, with a basal dash and often with a curvifascia mark -- a dark colored arc that extends from near the apex at the costal margin down to the reniform; hindwings are yellow to orange, with the usual dark postmedian band (Sargent, 1976). Schweitzer et al. (2011) also note that "the frosted appearance of the gray parts of the forewings is usually distinctive." |
| Wingspan: 48-55 mm (Sargent, 1976) |
| Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
| Immatures and Development: Larvae are illustrated by Schweitzer et al. (2011) and Wagner et al. (2011), but are extremely variable and can resemble those of other species. Consequently, they are only safely identified through rearing them to adulthood. |
| Larvae ID Requirements: Identifiable only through rearing to adulthood. |
