Reviewer Comments
An excellent record, Barry and Margaret. In 2025 there was a record from Cobnor (SW of Chichester) and now we have one, even further west, in Thorney Island. Looking at the distribution maps for the 1990-1994 and 2010 - 2014 county surveys, there are no records that far west.  Martin K
