Common in fens, reed-beds and marshes throughout much of the British Isles. In Hampshire and on the Isle of Wight probably occurs wherever Bulrush
Typha grows in numbers. Wingspan 40-54 mm. Similar to
Large Wainscot Rhizedra lutosa but shows a subterminal row of interneural dots or short, wedge-shaped streaks. Moths taken at light away from known breeding locations are invariably wandering females. Larva feeds on Bulrush, over-wintering as an egg.
