Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012) | Online Photographs: MPG, BugGuide, GBIF, BOLD | Technical Description, Adults: Forbes (1954); McCabe (1980) | Technical Description, Immature Stages: Wagner et al. (2011) | |
| Adult Markings: A medium-sized, red, brown, and gray Noctuid. The ground color of the forewings is reddish brown; the transverse lines, orbicular, and reniform are all grayish to whitish, with the spots somewhat darker inside. A strong basal black dash and a black median dash in the fold between the antemedian and postmedian lines are distinctive, together with the broad, pale gray subterminal band; the outer edge of this band is bounded by a white line with a well-defined w-mark between veins M3 and Cu1. Lacanobia subjuncta has similar basal and median dashes but lacks the pale subterminal band; Spirameter lutra has a similar subterminal band but lacks the median dash (McCabe, 1980) |
| Wingspan: 31-44 mm (McCabe, 1980) |
| Adult Structural Features: Male and female reproductive structures are distinct (see keys and illustrations in McCabe, 1980) |
| Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
| Immatures and Development: Larvae are pale tan or grayish, thick-bodied, and speckled with brown spots; a series of darker spots may occur dorsally. Larvae spend their time on the ground during the day (see Wagner et al., for a more detailed description and illustrations). |
| Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants. |
