A resident species usually occurring singly or sparingly by day and at mv light on a few herb-rich downland slopes and woodland clearings in East Sussex, although it is sometimes common on the chalk at Wilmington; in serious danger of extinction in West Sussex, where it was last seen during the mid 1990's. Extremely local and distinctly episodic in any numbers. Double-brooded, flying mainly from late April to early June and again from early July to late August. Larvae feed on thyme. (Pratt, 2011).
