Thank you Howard. I went because of this thread, so please do continue to post these notices. It was an excellent near three walk up around Guston this afternoon and finally some lovely weather for it. The group was quite small but very friendly.
I managed to spot this Orange-tip butterfly that sat and posed. I was quite pleased with this one as Orange-tips are almost impossible to photograph. They seem to barely land and are permanently on the move, indeed, in the last five years of trying this is the only one I've managed to catch.
