Guenée, 1852
witch hazel dagger moth, puzzling dagger moth
Acronicta hamamelis is a noctuid first described by Achille Guenée in 1852. The is closely associated with witch-hazel (Hamamelis), which serves as the larval plant. It occurs in eastern North America, with records from Canada and the northeastern and mid-Atlantic United States. The "puzzling dagger moth" reflects historical identification challenges.

Habitat
Associated with areas supporting witch-hazel (Hamamelis virginiana and H. vernalis), including deciduous woodlands, stream corridors, and rocky creek beds in the Ozark Highlands and eastern North American forests.
Distribution
Canada: Nova Scotia, Quebec, Ontario. United States: Maryland, Vermont, and presumably other parts of the eastern and midwestern United States where witch-hazel occurs.
Diet
Larvae feed exclusively on witch-hazel (Hamamelis spp.). feeding habits are not documented.
Host Associations
- Hamamelis virginiana - larval eastern witch hazel
- Hamamelis vernalis - larval Ozark witch hazel
Ecological Role
Herbivore specializing on witch-hazel; contributes to nutrient cycling in forest understory . Potential prey for insectivorous birds, bats, and other .
Human Relevance
No significant documented economic or cultural impact. Of interest to lepidopterists and naturalists due to its specialized association.
