For the county, we have a total of 153 records from 58 sites. First recorded in 1984.
Sutton & Beaumont, 1989: This species was added to the Yorkshire list in 1984, when a single moth was caught in the south of VC63. In Britain it is usually only found as far north as Lincolnshire (on a level with the south of VC63) in the east and Lancashire in the west, so it is not surprising that one should eventually find its way into Yorkshire. (The record shown on map 76 of MBGBI 10 in 10k square NZ50 was recorded in error and should have been removed before publication (JP pers. comm.).
Beaumont, 2002: Has consolidated its position and has been recorded at several localities in the south of the County since the mid 1990s.
VC61. Holme-on-Spalding Moor, 23.6.1996, 13.6.2000 (EDC); North Cliffe Wood, 16.6.1995; Rudston, 21.7.1996; Allerthorpe Common, 22.7.1996; Wheldrake Wood, 16.7.1997 (ASE); Spurn, 1.7.2000 (BRS). NEW VICE-COUNTY RECORD.
VC62. Wass, 21.7.1996 (PCI). NEW VICE-COUNTY RECORD.
Argus 52, 2006:
VC64. Tadcaster, 23.6.2006 (DBk). NEW VICE-COUNTY RECORD.
2012 (CHF): Bird’s Wing was first recorded in Yorkshire in 1984 when one was caught at Rossington in the south of VC63. It was rare until 2000 when it started to become locally common at various sites, mostly in the centre of the county. In 2011 year there was a significant spread to the west with three records at Spofforth and one even further west at Burley-in-Wharfedale. Comparing the current national distribution maps with the old maps from the 1980s, there has been considerable spread throughout Nottinghamshire and Lincolnshire and up into Yorkshire whilst populations in the west have not altered as much. It should be looked for in open broadleaved woodland and parkland where the larvae feed on docks and sorrels.
