described as a new species by Lafontaine and Troubridge in 2003
Numbers
one of 4 species in this genus in North America listed at All-Leps
Size
wingspan 25-29 mm, based on three Internet photos
larva length to 25 mm
Identification
Adult: forewing light to medium gray with distinct black lines and black-rimmed spots filled with ground color; reniform spot bent into V shape; orbicular spot oval or irregular-shaped, sometimes connecting to reniform spot; claviform spot narrow, pointed; AM line usually thin, slightly sinuate, bending outward at inner margin; PM line irregular, toothed; subterminal line scalloped, with paler shading beyond it; terminal line a series of black dashes; diffuse dark spot near anal angle; hindwing grayish with indistinct and diffuse subterminal band; fringe pale

Larva: head green, unmarked; body green with prominent white middorsal and subdorsal stripes; spiracular stripe white with dark green margin above
Range
British Columbia and Alberta to California and Arizona
Habitat
coniferous forests in western mountains; adults come to light
Season
adults fly from June to September
larvae from May to July
pupae in June and July
Food
larvae feed mainly on foliage of Douglas-fir; other hosts include Western Hemlock, Amabilis Fir, Grand Fir, Subalpine Fir
Life Cycle
one generation per year; overwinters as an egg
Remarks
Sometimes misidentified as Cosmia (=Achytonix) epipaschia, a species which is known only from a single specimen (the holotype) collected in New Mexico and described by Grote in 1883. See Remarks section on genus page for comments quoted from the Print Reference below.

An All-Leps image taken from this page seems atypical in that its AM line is thick, arc-shaped, and doesn't bend outward at the inner margin. Judging from the pin label, the specimen was collected in Summerhaven, Arizona; perhaps its appearance is more typical (?) of southern specimens.
See Also
Cosmia praeacuta forewing reniform spot is slightly curved but not bent into a V shape, and its AM line is heavy/thick, gently arc-shaped, and usually not bent outward at inner margin
