Priority Butterflies

In 2000, Butterfly Conservation published its South-Central England Regional Action Plan covering Dorset, Wiltshire, Hampshire & Isle of Wight. Following strict guidelines based on national importance, rarity and rates of decline, the Regional Action Plan (RAP) identified 15 high priority butterflies, of which 13 occured in Hampshire & the Isle of Wight.  Since then, a major review of UK Biodiversity Action Plan (UKBAP) species has taken place. The fully revised and updated list was published in 2007 resulting in significant changes to the national list of butterflies and moths (see Review Article by Bourn, N. (2007) pp. 19-21 in Issue 96 of Butterfly). The current list of high priority butterflies for Hampshire & Isle of Wight now also includes Dingy Skipper, Grayling, Wall, White Admiral, White-letter Hairstreak (all elevated from Medium Priority), and Small Heath. The full list of 18 species is as follows:

  • Adonis Blue (Polyommatus bellargus)
  • Brown Hairstreak (Thecla betulae)
  • Dingy Skipper (Erynnis tages)
  • Duke of Burgundy (Hamearis lucina)
  • Glanville Fritillary (Melitaea cinxia)
  • Grayling (Hipparchia semele)
  • Grizzled Skipper (Pyrgus malvae)
  • High Brown Fritillary (Argynnis adippe)
  • Marsh Fritillary (Euphydryas aurinia)
  • Pearl-bordered Fritillary (Boloria euphrosyne)
  • Purple Emperor (Apatura iris)
  • Silver-spotted Skipper (Hesperia comma)
  • Silver-studded Blue (Plebejus argus)
  • Small Blue (Cupido minimus)
  • Small Pearl-bordered Fritillary (Boloria selene)
  • Wall (Lasiommata megera)
  • White Admiral (Limenitis camilla)
  • White-letter Hairstreak (Satyrium w-album)

A further 2 species of butterfly are classed as medium priority, namely:

  • Chalkhill Blue (Polyommatus coridon)
  • Dark Green Fritillary (Argynnis aglaja)
