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 (VC10) trap on 2 Aug 2015, and which is therefore a first for the Isle of
Wight and for our area. Perhaps even more remarkably, the same recorder pulled in a second, on almost the same date in 2020. 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.
