Green Veined White

Took a walk along the River Gipping after work and saw lots of these butterflies on the thistles. Met a fellow photographer who had been photographing a rare Willow Emerald Dragonfly, he pointed it out to me but, alas, before I could snap it, it flew off. Apparently they are just in this part of the country so I will have to walk this walk again and hope I get to see it.
