SeasonalityAdults have been collected in Alberta in July and early August.
IdentificationA medium-size moth (3.0-3.4 cm wingspan) with dark and light grey mottled forewings and brown hindwings. Forewings are dark grey mottled with lighter, somewhat shiny lighter grey scales. The area below the stigma is not darker than the rest of the wing, like it is in most similar species of Syngrapha. The stigma is a pale green-gold or pale gold V or U-shape, higher than wide, with a small separate satellite spot. Hindwings are light yellow brown, shading to a wide sooty brown terminal band. The antennae are simple and the sexes are alike.
