Flame Wainscot Senta flammea
(Curtis, 1828)[Synonyms: Senta flammea]
Wingspan 32-40 mm.
A scarce and local species, restricted as a resident to a number of fens in East Anglia, though it sometimes occurs as an immigrant on the south coast.
Flying from May to July, the adults can be attracted to light and can be found resting on reed stems at night.
The larvae feed externally at night on common reed (Phragmites australis), hiding by day in hollow stems of the foodplant.
