Various species of butterflies have good years and bad years. In the previous 7 years I had barely seen any marbled white butterflies, and only photographed about half-a-dozen. This year I have taken hundreds of shots of them at different sites. After seeing large numbers in the Devil's Dyke railway cutting, I found more in the meadow at Bedford Purlieus (where they had a long season) and then at Woodwalton Marsh.
The marbled white is one of those butterflies that (in my opinion) is more photogenic with wings closed rather than open, here it is nectaring on knapweed. Despite its name, it belongs to the group of butterflies sometimes known as 'browns',
