Acronicta is a genus of noctuid moths containing about 150 species distributed mainly in the temperate Holarctic, with some in adjacent subtropical regions. The genus was erected by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Caterpillars of most Acronicta species are unmistakable, with brightly colored hairy spikes, and often feed quite visibly on common foliate trees. The hairy spikes may contain poison, which cause itchy, painful, swollen rash in humans on contact. The larva of the smeared dagger moth is unusually hairy even for this genus. Acronicta species are generally known as dagger moths, as most have one or more black dagger-shaped markings on their forewing uppersides. But some species have a conspicuous dark ring marking instead.
