Common NameMountain BeautySeasonalityAdults have been collected in Alberta from late June through early August.IdentificationA medium-size moth (2.9-3.2 cm wingspan) with reddish-brown forewings and bright yellow-orange hindwings. The forewings are brown with the lower two-thirds of the area between the antemedian and postmedian lines darker, almost black. Stigma is a silver dash and narrowly forked at the upper end. Hindwings are bright yellow-orange, with a black terminal band. Very similar to S. alticola, which has darker, blackish-brown forewings, a shorter stigma and a more zigzag terminal line. Other Syngrapha species with yellow hindwings (borea, orophila, microgamma) have mainly grey forewings and different stigmas. Autographa sansoni is larger and has pale yellow hindwings. There are also genitalic differences (see References). The antennae are simple and the sexes are similar. Older literature refers to ignea as S. hochenwarthi, a closely related Palearctcic species.

Life History
Adults of the Mountain Beauty are active both during the day and at night, and are attracted to lights. There is a single brood each season.
Conservation
A common widespread species; no concerns.
Diet Info
No Alberta data. The only available host plant information is from lab rearing at the CNC. Larvae in the lab were reared on blueberry (Vaccinium) but switched to willow (Salix) in the late instars.
Range
Primarily a western mountain species (northern Alaska south to southern California and New Mexico, with an apparently disjunct population in Labrador), but also found sparingly across the boreal forest and the…
Primarily a western mountain species (northern Alaska south to southern California and New Mexico, with an apparently disjunct population in Labrador), but also found sparingly across the boreal forest and the subarctic. In Alberta, it has been collected throughout the mountains and foothills, east to the Calgary and Lethbridge (?) areas. It should be watched for in the Alberta Cypress Hills and in the Boreal Forest region.
