Davey, P., 2009: A local species in England and Wales, the larva feeding on birch (Betula spp.), sallow (Salix spp.), larch (Larix spp.), beech (Fagus spp.), and various other deciduous tree and shrub species. In Dorset, the moth is local and tends to be confined to deciduous woodland containing birch and sallow in the eastern half of the county. Debate surrounds the possibility that this species is merely a form of the Engrailed1947, indeed Ectropis crepuscularia is not recognised as a distinct species on the Continent. Structurally there is no difference between the two, but externally, the ground colour is usually much whiter in this species.
Hill, L., 2014: Ectropis crepuscularia ([D. & S.]) is now considered a valid European species; E. bistortata (Goeze) is relegated to a specific synonym of E. crepuscularia ([D. & S.]) (Agassiz et al, 2013). The species that we call E. crepuscularia appears to be endemic to Britain. Agassiz (2003) informs us, however, that the name crepuscularia was first assigned to a moth caught in Vienna and so that must, of course apply to the European species. Thus, our E. bistortata (Goeze) is really E. crepuscularia ([D. & S.]) and our crepuscularia is in need of a valid new name! (Plant, 2008)
