"Around 25 million moth records from Butterfly Conservation's National Moth Recording Scheme and Moths Ireland have been combined to produce this landmark publication – the first ever atlas of all macro-moths in Britain, Ireland, the Isle of Man and the Channel Islands. Atlas of Britain and Ireland's Larger Moths includes accounts for 866 macro-moth species, each with a distribution map showing current and historical occurrences, trends, status, a phenology chart and colour image. A further 25 species, which were former residents, but have not been recorded from 1970 onwards, have a distribution map.Brief introductory chapters detail the long-standing tradition of moth recording and the development of the National Moth Recording Scheme, methods used to collect and analyse the data, an overview of trends since the 1970s and the environmental drivers of change in moth populations and distributions." -- Supplied by publisher.
