Davey, P., 2009: A species found throughout southern Britain, the larva feeding on hawthorn (Crateagus spp.), blackthorn (Prunus spinosa), ivy (Hedera helix), privet (Ligustrum spp.) and a variety of other deciduous and evergreen tree and shrub species. In Dorset, the moth is evenly distributed. 'The insect is not abundant and does not like fir woods, but it is a usual sight of an evening flying rapidly along country lanes, in rides in woods and about town in gardens and parks' (W Parkinson Curtis ms). Examples have been trapped occasionally during autumns following warm summers; these suggest a bivoltine tendency in recent years: 1989, 1997, 1999, 2003, 2005, 2006.
