IdentificationA small (1.7-1.9 cm wingspan) broad-winged yellow-brown and white moth. The forewings are pale cream with numerous wavy incomplete parallel cross lines of darker yellow-brown and light grey. Light postmedian band prominent where bending inward sharply before joining costa as large light patch. Prominent dark discal bars, Fringe checked white and light brown. Hindwings white or cream with yellow-brown marking on lower half, and with prominent dark discal bars. Adults and genitalia of both sexes are illustrated in Bolte, 1990. The light yellow-brown color and prominent discal bars on four wings will help separate niveifascia from most other western Alberta Eupithecia, although the genitalia should be examined for positive identification, in particular when specimens are worn.

Extreme southwestern Alberta west to Vancouver Island, north to northern coastal BC and south to New Mexico. The only Alberta record is a single specimen collected in Waterton Lakes National Park. The Type Locality is New Mexico.
Notes This is another of the western moths that reach Alberta in the extreme southwest. It has been found only in Waterton Lakes National Park, but likely will be found more widely in the mountains south of the Crowsnest Pass.
