This year I actually made 2 visits as the first, in early July, was on a particularly warm, sunny day and the butterflies were on the wing within around 45 minutes of my 6:00 AM arrival. On the plus side, the early morning sunshine provided very attractive light conditions during that short period. The second visit in mid July was on a much cooler, grey day. This meant more co-operative butterflies but less attractive light. Nothing's ever simple is it?!
The following were my favourite images from the first visit. The images from the second visit will form a later blog post.
