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.
