SeasonalityAdults are on the wing from early June to early July (Freeman, 1972: 696). Identification"Antenna with alternating black and white annulations. Head rusty, Thorax and forewing yellowish brown. Fringe whitish. Hind wing pale grey; fringe whitish. Fore- and mid-tibiae purplish black inwardly, whitish outwardly. Hind leg cream colored. Wingspread 10.0-11.5 mm." (Freeman, 1972: 696). Male genitalia is discussed and illustrated in Freeman (1972: 696; fig. 26). In Alberta, this species can be distinguished from other Argyresthia species by its smaller size, uniform yellowish-brown color of forewings, and its food plant, balsam fir. To an extent it resembles A. columbia, but its color, male genitalia, and food plants are different.
