Euxoa adumbrata

Euxoa adumbrata, the sordid dart, is a moth of the family Noctuidae.^[1] The species was first described by Eduard Friedrich Eversmann in 1842. In North America it is found across northern Canada from Quebec to western Alaska, south to the northern parts of the United States, and in the mountains to Colorado. It is also found in Greenland, the coastal areas of Scandinavia and the Ural. It was recently recorded from Denmark, although this includes Euxoa lidia, which some authors regard to be a valid species.
