A RARE butterfly has been spotted in Royston.

David Hatton, of the Ridings, Royston, captured a picture of the White-letter Hairstreak butterfly while it fed on newly planted flowers in his front garden.

The butterflies are rarely seen in the wild as they usually feed at the top of tall elm trees. Their population was decimated in the 1970's by the spread of Dutch Elm disease, although it is now thought to be recovering.

Mr Hatton, who is a member of Royston Photographic Society, also spotted one of the creatures in Poplar Drive, Royston.
