We relaxed into our camp chairs ... and saw a big blue butterfly land in a shrub several metres away. That was the end of relaxing.
It was a male Common Eggfly Butterfly Hypolimnas bolina nerina (known in New Zealand as the Blue Moon Butterfly). Apparently each male defends a territory about 30-40 metres apart and usually rests on a leaf one or two metres above the ground. This particular butterfly was not very active so I was able to get a reasonable photo.
