Davey, P., 2009: A species that is restricted to England, the larva feeding for two or three years in a stem or branch (often no more than ten cm. in diameter) of a wide range of deciduous trees and shrubs. The caterpillar exudes an odour, a polyphenol called zeuzerine (C14H26O2), and this may be used by the insect as a defence mechanism against potential prey (MOGBI Vol 2). Damage to commercially grown crops is limited as larvae rarely 'infest' the host plant. In Dorset, the moth is locally frequent in woodland and gardens, but not to such an extent that it constitutes a pest. The male is readily attracted to light, but rarely more than a single moth is observed on any given night during its flight period. Larvae have been detected within sycamore (Acer pseudoplatanus), apple (Malus domestica) and oak (Quercus spp.) across the county.
