A Red Data Book species, protected under the UK Wildlife and Countryside Act, and a priority species under the UK Biodiversity Action Plan, in woodland clearings and flower meadows; widespread in mainland Europe and Fennoscandia, known in Britain from Cornwall, Devon and Kent; mainland Europe and Fennoscandia. The records that exist from Hampshire almost certainly result from deliberate introductions, particularly in Pamber Forest where attempts were made to establish it in the 1950s and 1960s: it is not known to be indigenous in the county. A population was established for a short time in the Aldershot area in the 1950s. Wingspan 40-44 mm. Larva feeds on Common Cow-wheat, Ribwort Plantain, Germander Speedwell and Foxglove.
