I have seen very few butterflies this year and managed to take even fewer photos of them.  This is a very cropped attempt of a Wall which stayed just long enough for my blip.  It loves to bask on wall, rocks and stony places with its patterned undersides looking like tree bark or mottled stone and a row of false eyes providing good camouflage against a stony or sandy surface.   Numbers are declining in England and it is now on the Priority list yet it is spreading in southwest and south east Scotland probably due to global warming.  .Since first being recorded in East Lothian in 2010 it is now spreading throughout the area. It had been quite common in Scotland in the early 19th century until a series of cold summers in the 1860s wiped the Wall butterfly out except in south west Scotland. An interesting account written last week of the spread of butterflies from England into East Lothian is here.
