The three images below were taken last week at Cabilla Wood near Bodmin and the darker valesina form at Bentley Wood near Salisbury. I went to Bentley Wood hoping to see Purple Emperor. Sadly it was too windy and quite dull so I dipped. A shame really as this year has been exceptional for the species with up to 100 individuals being seen at some localities. Back to the Silver-washed... the valesina form is unusual but not rare. I saw two of them on Sunday but this was the darker one.
