Davey, P., 2009: A generally distributed species in Britain, the larva feeding on birch (Betula spp.), and less frequently on beech (Fagus sylvatica), hazel (Corylus spp.) and alder (Alnus spp). This is the largest of the Emeralds, with a wingspan of up to 65mm. In Dorset, the moth is most frequent where birch grows in deciduous woods on sandy and clay soils and on heaths. Favoured sites include Arne Wood, Hurn, Whitesheet, Boys Wood and Castle Wood. Elsewhere it is scarce.
