Common NameQuestion Mark Looper SeasonalityAdults have been collected in Alberta from mid-July through early September. IdentificationA medium-size (3.4-3.8 cm wingspan) moth with slate-grey and black forewings and sooty-brown hindwings. The forewing ground is black, with paler grey areas at the base, along the costa (especially near the apex area) and in the terminal area. The lower part of the postmedian line is often rusty-red. The stigma is highly variable, usually a thin, silver u or v-shape with a satellite spot distad. The fringe is checkered dark and light grey. The hindwings are dark, sooty brown, shading to a wide blackish terminal band. The antennae are simple and the sexes similar. It is most similar to S. octoscripta, and some specimens need to be determined by examining the genitalia. The end of the valve in interrogationis is sharply angled or pointed (rounded with a preapical spine in octoscripta), and in females of interrogationis the ovipositor lobes are rounded posteriorly (tapered to a narrow apex in octoscripta).
