73.041 [B&F: 2285] Marsh Dagger (Acronicta strigosa) ([Denis & Schiffermüller], 1775)

 

Formerly an uncommon resident in the fens of Cambridgeshire and Huntingdonshire, last seen in 1930’s. Since which it has appeared in southern England rarely as an immigrant from the continent, in East Sussex in 1996, and at Pagham Harbour, West Sussex, in July 2010, to which can be added one of the more surprising records of recent years, when an individual turned up in JHa’s Bonchurch (10) trap on 2 Aug, and which is therefore a first for the Isle of Wight and for our area. Wingspan 30-32 mm. Shows a strong black streak medially from base to claviform stigma, and two others in echelon above tornus (MBGBI Vol 10). Larva feeds on Hawthorn and Blackthorn.
