Foodplant and Larval Feeding Signs
In fens and beds of common reed of varying sizes, possibly preferring, but not restricted to, unmanaged beds.
Finding the Moth
Larva: feeds and overwinters in the dead stems of common reed and amongst the leaf litter on the ground. Carefully parted dead leaves of the shoots and decaying reed leaves on the surface of the litter layer will contain scattered pale brown frass and a little silk if a larva is present.
Adult: flies at dusk and later comes to light placed in amongst or very close to the larval foodplant.
Could be confused with Helcystogramma lutatella but that species has a more rounded end to the forewing.
Single-brooded from late May to early August.
