Two butterflies

Two butterflies at one time on the Buddleia today - pity neither had the wings open!  As it is closed I don't know for sure what this is but I think possibly a Red Admiral. The 'extra' is a white one  - but I don't know which one. Unfortunately my "Observer's Book of British Butterflies" Vintage 1952 doesn't show them closed, only open and as caterpillars so I will have to look online. Will edit if I find them.
