|scientific name Oeneis bore |
common name White-Veined Arctic
Moist alpine meadows.
One brood per year, peaking in late June to mid July.
The upperside is an even, unmarked grey-brown. The underside is striated black and grey-white, with a well-defined median band and white hindwing vein markings. The banded underside pattern is vaguely visible on the upperside through the thinly scaled veins. O. polixenes has a similarly banded underside, but lacks the white veins.
Subspecies edwardsi is found in Alberta. The appropriate name for this species may be taygete (named from eastern North America) rather than bore (named from Europe), based on differnences in genitalic structure and larval colour (Tuzov 2000, Guppy & Shepard 2001).
Unknown in Alberta. Biennial at Churchill, MB and in Europe. The eggs are laid on dead grass blades. Manitoba larvae are brown with paler and darker longitudinal lines, and overwinter when young and again as fourth or fifth instars. Flies only in alternate years in some localities (Scott 1986), but present every year in Alberta.
Not of concern.
The larval hosts are unknown in Alberta. Carex misandra and likely Festuca species are used at Churchill, MB. Adults occasionally visit flowers (Scott 1986).
Alaska to Labrador, south to the central Rockies of Alberta, with isolated populations in the Rocky Mountain States and Maine (Scott 1986).
