Resident. In danger of extinction in both vice-counties. Larvae are sometimes fairly common to common amongst sand-dunes and on vegetated shingle beaches but adults generally only occur singly at mv light. Very local, and chiefly found on the Selsey Peninsula and near Rye, although sightings have been made in a few places elsewhere along the East Sussex coast. Single-brooded, flying mainly from late July to late August, occasionally from the second week of July. Larvae feed on prickly saltwort. (Pratt, 2011).
