scientific name    Argyresthia abies    

habitat
Primarily boreal habitats with the larval food plant, balsam fir (Abies balsamea).

seasonality
Adults 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.

life history
The larva bores in the terminal twigs of balsam fir (Freeman, 1972: 696).

conservation
Not of concern.

diet info
All type material reared from larvae on balsam fir, Abies balsamea (Freeman, 1972: 696).

range
This species is recorded from Lac La Biche in Alberta. Also recorded from the vicinity of Big River in Saskatchewan (Pohl et al., in prep.) and northern Ontario.
