Moth on brink of extinction found flying at secret Scottish site

Discovery of dark bordered beauty males where caterpillars were released raises hopes species can be revived

A moth on the brink of extinction in Britain and reared for the first time in captivity has been found flying at a site where its caterpillars were released.

The dark bordered beauty is clinging on in just three places in Britain but its numbers are being increased by a conservation project to establish new populations in the Scottish Highlands.
