Argus 56, 2008: First recorded in Yorkshire in 2007 from all five vice-counties, this moth has now been recorded far more widely throughout the county. There are many records from the Barnsley, Doncaster and Sheffield districts of VC63 but it remains infrequent in the Rotherham area where many Horse Chestnut trees remain unaffected at present. There is a suggestion that road transport may have played a part in the distribution of this moth as there is a concentration of records along the route of the A1 road.
Current status (HEB, 2011): A moth that was not described until 1985 from Macedonia, it has spread rapidly across Europe and was first recorded in Britain in 2002. Following an explosive range expansion it arrived in all five Yorkshire vice-counties in 2007 and has since become widespread and abundant.
