Davey, P., 2009: A local species in southern Britain, the larva feeding inside the stems and then nocturnally on the blades and flowers of various woodland grass species. In Dorset, the moth is local and at low density in old woodland on sandy and chalky soil where false brome (Brachypodium sylvaticum) and wood meadow-grass (Poa nemoralis) grow. In Oakers Wood and Powerstock Common, good stocks of wood-rush (Luzula spp.) may account for the relatively high numbers of moths trapped there. It is also common very locally in old woodland on chalky soil in the north-east of the county where wood melick (Melica uniflora) and wood millet (Milium effusum) grow alongside false brome and wood meadow-grass.
