2375 Large Wainscot Rhizedra lutosa
(Hübner, 1803)Wingspan 42-50 mm.
Frequenting reed-beds and riversides, this is a fairly common species in much of England, especially in the south and east. Further north and west it becomes more local, ranging into southern Scotland.
The larvae feed in the bases of stems and the roots of common reed (Phragmites australis).
The adults are readily attracted to light and are on the wing from August to October.
