Alberta Beauty

An uncommon but widespread species; no concerns.

Adults have been collected in Alberta in June and July.

A western mountain species, found from Alaska south to Oregon, Idaho and Arizona. In Alberta it can be found throughout the foothills and mountains.

A medium-size (3.4-3.6 cm wingspan) moth with dark chocolate or rust-brown forewings and yellow-buff hindwings with a wide, dark terminal band. There is a prominent silvery stigma on the forewings, shaped like a shallow arc and slightly forked at the upper end. The wide terminal band on the hindwings is sharply divided from the yellow basal two-thirds. The antennae are simple and sexes are similar. Sansoni could be mistaken only for one of the Syngrapha species with yellow hindwings (i.e. orophila, borea, ignea etc.) but these are all either much smaller or have different shaped stigma on the forewings.

Coniferous forest in the mountains and foothills.

Adults are nocturnal and come to light. There is a single brood per year.

Unknown.
