Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Immature Stages: Wagner et al. (2011)                                                                                 
Adult Markings: The ground color is dull or reddish-brown, sometimes with purplish shading (Forbes, 1954). A dark median shade is the strongest marking and is strongly incurved at the inner margin. The orbicular is typically very small or missing but the reniform is well-defined and solid brown, not divided by a pale line as in asopialis. A terminal dark brown or reddish-brown patch is present, bordered by a subterminal patch that is often yellowish but not contrastingly dark brown as in asopialis.
Forewing Length: 20-25 mm (Forbes, 1954)
Adult Structural Features: The palps are very long in both sexes. In females, they project forward but in males, they are recurved over the back and somewhat covered over by the adjoining scales of the thorax; they are also pale, forming what appears to be a pale yellowish or off-white median line, but not as orange-yellow as in asopialis.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Larvae ID Requirements: Identifiable from close inspection of specimens or by DNA analysis.
