Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1954, as Plusia ou); Lafontaine and Poole (1991)                                                                                 
Adult Markings: A medium-sized, dull, ash-gray Looper. Lines on the forewing are non-contrasting and inconspicuous, but both the antemedian and postmedian are doubled, pale filled, and waved rather than even (Forbes, 1954). The subterminal is somewhat irregular, with a dark shade on the basal side and a pale gray shade beyond it; both the apex and anal angle usually are marked with pale gray. The stigma is a rounded, open u-shape, without a silver filling; a small silver spot, sometimes with a dark center, follows. Hindwings are dull luteous.
Wingspan: 35-40 mm (Forbes, 1954)
Adult Structural Features: The only species of Plusiine in our area with spines on the tibiae of all three pairs of legs (Lafontaine and Pool, 1991).
