73.035 [B&F: 2290] Reed Dagger (Simyra albovenosa) (Goeze, 1781)

 

Nationally scarce (Nb) in reed-beds, marshes and fens in parts of south-eastern England. In Hampshire and on the Isle of Wight there was a colony in Freshwater Marsh on the Island until 1989 and at Titchfield Haven from 2000. It was also reliably reported from Browndown but since then the area has been largely filled in. Wingspan 32-40 mm. The pure white hindwing distinguishes Reed Dagger from a number of superficially similar wainscots. Larva feeds on Common Reed, over-wintering as a pupa.
