A trip to Warton Crag to look for Pearl-bordered and/or Small Pearl-bordered Fritillary proved frustrating although I did find a nice fresh male Northern Brown Argus. The colour of the NBAs here seems very dark brown and quite distinct from the warmer brown colour of the Brown Argus found on the South Downs. I then moved on to Gait Barrows where ironically I found a Small Pearl-bordered Fritillary which stopped long enough for me to take a photograph.
