Common NameDecorated Granite SeasonalityFlies primarily in July and August, peaking in late July. IdentificationForewing pale grey with fine dark striations and usually weakly developed costal wedges; Black AM and PM lines variably developed, median line usually absent. Black discal spot. Hindwing slightly paler, sometimes with PM and submarginal line and discal spot. Terminal line finely checkered black and white. Sexes similar. Wing pattern very similar to some Semiothisa, but these have simple male antennae, not pectinate as in Itame. Bowman (1951) erroneously reported Alberta specimens of this species as I. denticulodes (Hulst) (McGuffin 1972).
