73.038 [B&F: 2284] Grey Dagger (Acronicta psi) (Linnaeus, 1758)

 

Notes: Common in woodland, hedgerows, gardens, scrubby heathland, calcareous grassland, fens and a wide range of other habitats; low altitudes in the north throughout much of the British Isles, a species of conservation concern under the UK Biodiversity Action Plan. In Hampshire and on the Isle of Wight very much more common than Dark Dagger, but undoubtedly under-recorded. Wingspan 33-44 mm. Very similar to Dark Dagger A. tridens, from which separated only by dissection of the genitalia. The larvae of the two species are readily identifiable. Larva feeds on various broad-leaved trees and shrubs, including Blackthorn, Hawthorn, Apple, Birch, Common Lime, English Elm and Rowan, over-wintering as a pupa.
