Argus 69, 2013: The most notable addition of the year. Only seven previous British specimens are known, all from a single locality in Cambridgeshire in the early 1970s and the species was considered to be extinct in Britain. The 2011 and 2012 records below result from retrospective re-appraisal of genitalia determinations made by CHF following the identification of the moths taken in 2013.
