About Acronicta vulpina (Grote, 1883)
Acronicta vulpina, commonly known as the vulpina dagger moth or miller dagger moth, is a moth species belonging to the family Noctuidae. This species was first formally described by Augustus Radcliffe Grote in 1883. It is native to North America, where its range extends from New York and Newfoundland west to central British Columbia, and south to Colorado. Acronicta vulpina was formerly classified as a subspecies of Acronicta leporina; both of these species occur in eastern Russia. The wingspan of adult Acronicta vulpina measures 40 to 47 mm. Depending on location, adult moths are active in flight from May to July. The larvae of this species feed on Populus tremuloides, Betula papyrifera, Populus balsamifera, Alnus rugosa, and Salix species.
