Sutton & Beaumont, 1989: Only relatively recently added to the County list, this species appears to be rather local but recorded from widely scattered areas. It may well be much more frequent than it appears since it is very difficult to distinguish from P. festucae (Linnaeus). However, there are at least four areas where all the Gold Spots which have been checked have proved to be festucae (Spurn, Sheffield, West Melton and Denaby lngs). This would indicate that it is definitely local to some extent. Although a larval foodplant is not given by Lorimer (MBGBI 10) or Skinner (1984), larvae have recently been discovered openly feeding on purple small-reed (J. Fenn per MRB). It might well be worthwhile to search for larvae on this foodplant at suitable sites in Yorkshire.
2012 (CHF): Much less common in the county than Gold Spot and univoltine (unlike Gold Spot) flying mostly in July and August. Rare in the south and east but commoner on the higher ground in the north and west. See Gold Spot for information on separating these two species. Whilst identification is fairly straight forward in most cases, some individuals need dissection in order to be sure.
