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.
Mythimna is a genus of moths in the family Noctuidae described by Ferdinand Ochsenheimer in 1816.
Agrotis is a genus of moths of the family Noctuidae. The genus was erected by Ferdinand Ochsenheimer in 1816. A number of the species of this genus are extinct.
Hadenini is a tribe of cutworm or dart moths in the family Noctuidae. There are more than 140 genera and 1,000 described species in Hadenini, found worldwide.
Xanthia is a genus of moths of the family Noctuidae.
Acontia is a genus of moths of the family Noctuidae. The genus was named by Ferdinand Ochsenheimer in 1816. Eusceptis, Pseudalypia and Spragueia are sometimes included in the present genus, but here they are tentatively treated as different pending further research. Many species of Tarache were also once placed here.
Agrochola is a genus of moths of the family Noctuidae. The genus was erected by Jacob Hübner in 1821.
Cucullia is a genus of moths of the family Noctuidae. The genus was erected by Franz von Paula Schrank in 1802.
Diarsia is a genus of moths of the family Noctuidae.
Egira is a moth genus in the family Noctuidae. This genus has several species, including Egira crucialis, that are on wing in winter and early spring. They are sometimes, along with members of the Orthosia genus, called early spring millers.
Eupsilia is a genus of moths of the family Noctuidae.
Lacanobia is a genus of moths in the family Noctuidae.
Leucania is a genus of moths of the family Noctuidae first described by Ferdinand Ochsenheimer in 1816.
Lithophane is a genus of moths of the family Noctuidae. They spend the winter as adults. Some species are capable of feeding on other caterpillars or on sawfly larvae, which is rather uncommon among Lepidoptera.
Orthosia is a genus of moths of the family Noctuidae erected by Ferdinand Ochsenheimer in 1816. As with the genus Egira, moths in this genus are sometimes called early spring millers, as adults are on wing in winter and early spring. Species of note are the Hebrew character, the common Quaker, and the speckled green fruitworm moth.
