A resident species generally occurring singly in reedbeds, but it is sometimes fairly common near St Leonards. Only sparsely distributed, and apparently currently completely missing from the north of the county. Distinctly episodic in appearance everywhere. This species is single-brooded flying mainly from early June to late August. Larvae feed in the stems of common reed, reed sweetgrass and sedges. (Pratt, 2011).
