Migrant

Immigrant and suspected episodic resident. Occurs sparingly in a few localities in both vice-counties, very rare in East Sussex. Single-brooded, flying mainly from mid July to late August. Larval foodplant has yet to be determined in Sussex, although oak has been listed elsewhere. (Pratt, 2011).
