Michael Blencowe of the Sussex branch of UK Butterfly Conservation Organization runs a Grayling Festival walk every year. Bea and I arrived on Saturday in time for an informative talk at Windover Hill (near the Long Man of Wilmington). During the walk 29 species were seen, though we missed some as we did not do the whole walk. Many Graylings were seen, they are well camouflaged and glide after takeoff. The views of the Downs were wonderful.
