First One Snapped

This is not the first butterfly I've seen this year ( the others were Brimstones on the wing ) but it is the first one that has sat still enough to get a photo of :-)
A glorious day out there and yet again housework was put off in favour of a walk this afternoon ........well you have to make the most of it while it's there, don't you....it never seems to last very long......I'm guessing it will be 'all change' tomorrow :-/
