I also kept an open-eye for butterflies and was not disappointed. Unfortunately, a fresh-looking Peacock escaped the camera but I did find a pair of Large White feeding on Common Knapweed. I think this is the male ...
And I photographed a Painted Lady for the first time ...
These Wall butterflies were a real bonus and a lifetime tick. The male (upper) was typically hyper-active, patrolling his territory, settling frequently if briefly on sunnier parts of the path we shared, before eventually coming upon his mate, if mate she was, in the path-side grass. He then head-butted her half a dozen times before pausing just long enough for them to have their picture taken.
Phil Gates has a fascinating piece on his Cabinet of Curiosities blog about Wall butterfly behaviour including the head-butting I observed.
