Found on coastal and downland habitats. Marked decline in UK – Habitat loss and fragmentation. New to national list of BAP priority species 2007

Extinct in Norfolk – Last recorded in early 1900s. May be candidate for reintroduction. Internationally threatened and international responsibility - Agricultural improvement of marshy and chalk/limestone grasslands, afforestation and development of habitats, changes in grazing stock and practice, fragmentation and isolation of habitats. Primarily associated with coastal grasslands, although can be found on some inland sites. Marked decline in UK – Loss, degradation and fragmentation of habitat. New to national list of BAP priority species 2007 Found in a wide range of grassland habitats Marked decline in UK – Reasons for decline are unclear.Disappeared from almost everywhere in Norfolk except north and east coasts, and third most likely candidate for regional extinction after Dingy and Grizzled Skippers (Andy Brazil, pers.comm) New to national list of BAP priority species 2007 Associated with woodland containing honeysuckle (Lonicera periclymenum) with rides and clearings. Given as having a marked decline in UK on the BAP list, although appears to be expanding its range northwards. New to national list of BAP priority species 2007 Current UK Species Action Plan. Associated with heathland habitat. Declining, although reintroductions have enhanced existing populations and re-established previously extinct colonies. Norfolk Action Plan published June 2006.
