Davey, P., 2009: A generally distributed species in Britain, the larva feeding on rosebay willowherb (Chamerion angustifolium), broad-leaved willowherb (Epilobium montanum), and related species. In Dorset, the moth is widely distributed and found in a various habitats. It occurs near rivers, streams, ditches and ponds where rosebay willowherb abounds, and in disturbed woodland, hedgebanks, gardens and waste places where broad-leaved willowherb grows. It has been found most commonly at Whiteway Fen where hoary willowherb (Epilobium parviflorum) and marsh willowherb (Epilobium palustre) grow amongst rushes in pasture made wet by chalk springs emerging from the ground. The peak of the second brood is, on average, nearly five times larger than that of the first brood.
