Elusive Butterfly

I have a Buddleia tree in the garden and and today the Butterlfies paid it a visit. So I ran into the house grabbed the camera but trying to capture one sitting still was almost impossible they flit about so quickly and when they did eventually stay still they closed their wings so no colour was showing just the brownish dull underside not the best look. They seem to have a sixth sense when you are approaching them but I persevered and eventually I think the poor thing just got tired of me chasing it, and gave in gracefully.
