description Grey dagger moth Overview
The grey dagger is a species of noctuid moth found across the Palearctic region, including Europe and parts of Asia. First described by Carl Linnaeus in 1759, the adult moth is easily recognized by its pale grey forewings, which feature distinctive black, dagger-shaped markings. These nocturnal insects typically inhabit woodlands, hedgerows, and gardens. The larvae are generalist feeders that consume the foliage of various deciduous trees, such as oak and hawthorn, before pupating in the soil.
help Grey dagger moth FAQ
What is the scientific name of the grey dagger moth?
The grey dagger is Acronicta psi, a noctuid moth found across much of the Palearctic. It is closely related to the dark dagger, Acronicta tridens.
How can I tell a grey dagger moth from a dark dagger moth?
Wing markings alone are often insufficient because Acronicta psi and Acronicta tridens can look extremely similar. Specialist identification may require examination of genitalia rather than relying only on the grey forewings and dagger-shaped markings.
Where does the grey dagger moth live?
It occurs across Europe and parts of Asia within the Palearctic region. Adults are commonly associated with vegetation and woodland-edge habitats where the caterpillars can feed on broad-leaved plants.
When was the grey dagger moth described?
The species was described by Carl Linnaeus in the 18th century and is generally cited as Acronicta psi (Linnaeus, 1758). Some catalogues display slightly different historical dating conventions, so the scientific authority is the safer identifier.
