Davey, P., 2009: Generally distributed in Britain, becoming less common in northern districts, the larva feeding on a wide range of deciduous trees and shrubs. The wingless female remains close to its empty cocoon. "Generally and evenly distributed in Dorset. Occasionally on tamarisk, roses, and fruit trees, it rises to being a minor pest. The male is a frequent sight on the wing on sunny autumn days." (W Parkinson Curtis ms). In addition to this, the moth also flies at night and has been found in light traps on more than hundred occasions in recent years. The species is usually single-brooded in August and September in the UK, however, an additional bivoltine cycle may explain the protracted flight period of four months between 25 June and 27 October.
