Indeed we did. See my diary: viewtopic.php?f=29&t=4056&start=500#p85681 But no Pine Martens (you lucky devils!).I hope you and Mike had a fruitful afternoon, Jack.
But yesterday on Mull did get a "black-veined white"

Little clue about finding Chequered Skippers. If you are not attacked by millions of midges, then it's not CS habitat (too dry I guess).
But not of course the other way round, ie millions of midges doesn't guarantee CS otherwise Mull would be swarming with the butterfly
