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.
