73.037 [B&F: 2283] Dark Dagger (Acronicta tridens) ([Denis & Schiffermüller], 1775)

 

Notes: Common in woodland, fens, gardens and a wide range of other habitats throughout much of England and Wales. In Hampshire and on the Isle of Wight very much less common than Grey Dagger, although undoubtedly under-recorded owing to similarity to that species. Wingspan 33-44 mm. Very similar to Grey Dagger A. psi, 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 Wild Rose, Cultivated Rose, Hawthorn, Blackthorn and Goat Willow, over-wintering as a pupa.
