Libby & Rick Avis
Similar Species: Syngrapha abstrusa, alias, cryptica and rectangula cannot be reliably separated using DNA barcoding, PLoS ONE 12(6): e0178548; Suppl. Table S8. Examiantion of genitalia is usually required. Rectangula has a West Coast dark form similar to alias. In Maine and the Maritime Provinces, specimens thought to be a dark form of rectangula have proven to be cryptica. "The inland form [of cryptica] has brown shades in the forewing and the silvery areas, especially in the basal area, have a definite greenish tone, so they are relatively easy to pick out - especially after you've seen a real one in the flesh." - Chris Schmidt & Don Lafonataine (pers. comm., 03/5/2018)
