Davey, P., 2009: A relatively recent colonist of England, first recorded on the Isle of White in 1951 and now found as far north as Lancashire, the larva feeding on cypress (Cupressussuga spp.). In Dorset, the first record was of eight moths trapped at Durlston in the first week of October 1959. The following year, it was found at Studland and over the next ten years it moved rapidly northwards and westwards to colonise much of the county. It is common wherever monterey cypress (Cupressus macrocarpa), leyland cypress (x Cupressocyparis leylandii) and lawson's cypress (Chamaecyparis lawsoniana) has been planted in hedges. The moth is found in Iberia, France and Belgium.
