SeasonalityThe Alberta records are all of adults collected in the latter half of July. IdentificationA medium-size moth (3.0-3.3 cm wingspan). The forewings are dark grey or grey-brown with the lower half of the median area blackish. There is a thin U-shaped silver stigma with a short projection outward from the bottom of the U. Hindwings are pale buff or yellow-brown with a broad dark terminal band. Very similar to S. borea and S. orophila, but those species have yellow instead of buff or yellow-brown hindwings. There is also often a faint median line in diasema, lacking in similar species. The antennae are simple and both the sexes are similar.
