Field Guide Descriptions: | Online Photographs: MPG, BugGuide, GBIF, BOLD | Technical Description, Adults: Forbes (1954, as Oncocnemis perscripta) | Technical Description, Immature Stages: Forbes (1954); Wagner et al. (2011) | |
Adult Markings: A medium-sized, pale gray to grayish brown Noctuid with well-marked transverse lines and spots. The ground color is fairly uniform but the basal third may be somewhat darker. The antemedian and postmedian lines are both constrastingly black and sinuous or waved; the antemedian is often bordered anteriorly with a brownish shade. The orbicular, claviform, and reniform spots are all large and represented by fine black outlines that are filled with the ground color. A subterminal line composed of small spots may also be present. Hindwings are dirty-white (Forbes, 1954). |
Wingspan: 30 mm (Forbes, 1954) |
Adult Structural Features: Male and female reproductive structures are illustrated but not described by Troubridge (2008) |
Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: Larvae are strikingly patterned with yellow, black, and white. A series of large mid-dorsal yellow, white-ringed spots are bordered by black subdorsal bands, which are bordered below by wide spiracular stripes of yellow. The head and lateral stripes are spotted with black (Forbes, 1954; Wagner et al., 2011). |
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants. |
