Its species numbers are declining in England. It occurs in damp, grassy habitats, woodland clearings and moorland. Has also been found in dune slacks and coastal cliffs.
Foodplants and eggs
In the UK this species uses several species of violet as foodplant. In dryer areas Dog Violets are used whilst in wetter areas the fooplant is Bog Violet Viola palustris, or Marsh Violet growing amongst Purple Moor-grass or Tufted Hair-grass. They prefer the damper areas more often. They occur amongst bracken where this is shading the appropriate violet species.
