Purple Hairstreak, Fermyn Woods, Northants. July 2011.
  In Fermyn Wood we met two bikers who had spread icing from a slab of cake over oak leaves in the hope of attracting
  a Purple Emperor.   Instead they attracted this male Purple Hairstreak, who really liked this leaf - when removed,
  he immediately returned.   He must have been photographed by everyone who passed down that path.
