Davey, P., 2009: A widespread species in Britain, the larva feeding on nettle (Urtica dioica) and dead-nettle (Lamium spp.), and occasionally on various other herbaceous plants. In Dorset, the moth is widespread and frequent, but at low density in open, unimproved grassland on all soil types, but rises to common in areas where improved farmland provides nitrogen-rich soils where nettle plants flourish. This is therefore one of the very few moth species to benefit from changes in agricultural practices in recent years. The moth is bivoltine and the peak of the first brood is on average, twice as large as the peak of the second. Recorded in 41 (103%) of 40 10k Squares. First Recorded in 1930. Last Recorded in 2019.
