Abstract A new species of the genus Plusia Ochsenheimer is described from North America on the basis of differences in wing colour, markings, and genital structure. The new species, typically found in bogs, was first recognized through molecular sampling for the Barcode of Life Initiative and differs significantly from other species of Plusia in the cytochrome c oxydase I (COI) mitochondrial gene sequence.
