Just got back from the old quarry adjacent to Bath Golf course. Saw a fritillary, on three separate occasions. Probably the same individual. Flew past me twice, and once seen settled about 20ft away down the butterfly slope. As best I could see, markings were similar to Small Pearl-Bordered Frit I saw on Saturday at Crook Peak, but fresher/deeper orange, and in flight it seemed less delicate. Definitely a new species for the site for me, but I only wish I knew for sure which Could be a release, I suppose - I don't know of any other May/June Frit sites in the vicinity.
Lots of Common Blues and Small Heaths around.
