Davey, P., 2009: A generally distributed species in Britain, the larva feeding nocturnally on the flowers and immature seeds and later the foliage of various grass species. In Dorset, the moth is widespread and generally at low density, but although locally frequent in the vicinity of deciduous woodland, where for example false brome (Brachypodium sylvaticum) and wood meadow-grass (Poa nemoralis) are potential host plants, it is rare on coastal grassland and on heathland. In Dorset, the moth is usually on the wing between early May and early July, but a partial second generation occurs occasionally during August. The moth has two basic forms; the darker of these two (see photo) is known as ab. combusta.
