During the big butterfly "invasion" at the beginning of October, Geoff and Evelyn Bailey paid a visit to Haddenham's Old Burial Ground, now a pocket nature reserve, and witnessed zillions of Red Admirals, many of which were resting on tombstones. One supposes that the insects were getting mineral salts from the stone. Or maybe they were just basking in the warm autumn sunshine. Anyway, it makes a splendid picture. Thanks, Geoff, thanks Evelyn, for the photograph.
