Nice picture Charles.Went back to Burwell Cutting. This time there were plenty of Green Hairstreaks flying....
I braved the dogs and their calling cards at the Newmarket end of Devil's Dyke today. Met Guy Manners there. He had seen just one GH; I saw none

Can someone confirm that the seedling tree in this piccie is a Sycamore? Or is it an Elm? (near the car park) I didn't in fact notice it at the time when photographing the butterfly.
