I have received a report of 3-5 Argent & Sable at Shapwick Heath on Friday (1st June). I recorded 7 at the site on Saturday (2nd June). Also saw a Epinotia bilunana and Brown Silver-lines. On the was back to Dorset saw a Small Eggar larval web in the roadside hedge.
Any further records of Argent & Sable or other UK Biodiversity Action Plan species would be welcomed (contact me if you would like details), thanks Kelly Thomas, Butterfly Conservation (email@example.com).
