Rare moth in severe decline at its last English site

Numbers of a rare species of moth -- found only in York in England -- have tumbled in recent years, a team of scientists has discovered. The Dark Bordered Beauty (Epione vespertaria) is found on Strensall Common, an area of protected lowland heath near York. This is the last known English site for the moth, although there is a handful of populations in Scotland, where the moth is also rare.
