Fen Wainscot Arenostola phragmitidis

(Hübner, [1803])


Wingspan 32-36 mm.

A distinctively plain-looking species with creamy forewings fading to rufous at the outer edge.

It is distributed mainly in the south and east of England, westwards to Dorset, and also locally in the north-west of England.

Flying in July and August, the adults can be attracted to light.

The caterpillars feed internally in the stems of common reed (Phragmites australis).
