Species Account

Sutton & Beaumont, 1989: Spurn Point (VC61) has the most northerly British colony of this mainly salt-marsh species. It was first recorded there in 1905 (YNU, 1970) and the colony is still thriving (BRS; Sutton & Spence, 1974a).

Argus 58, 2009: A bit of a recovery this year at its only site in the county, but not to the numbers seen a few years ago.
VC61. Spurn area, 13 records of 18 moths between 1.7 & 18.7.2009 (BRS, PAC).

2012 (CHF): Still present at Spurn where numbers have decreased a little in recent years.
