Status and Distribution
Local, occasionally locally common, in southern and eastern England, the Midlands, Wales and the Channel Islands, becoming more localised in Ireland and northern England and very local in southern Scotland and Northern Ireland. There are some indications it may be expanding its range northwards with three new vice county records in central and western Scotland during 2014 and in 2020, however this could be down to increased recorder activity. The moth is apparently absent from many parts of the northern British Isles where bracken is abundant and it is suggested that it possibly prefers more sheltered sunny aspects (Sterling, Parsons and Lewington, Field Guide to the Micromoths of Great Britain and Ireland, 2012).
