For the county, we have a total of 1275 records from 44 sites. First recorded in 1860.
Sutton & Beaumont, 1989: Now quite well established in south-east Yorkshire, and probably found along much of the Humber shore (Sutton & Spence, 1974a). There have been a few sporadic records from elsewhere in the County.
Beaumont, 2002: An extraordinary run of records since 1997 from two inland localities in VC63 at West Melton and Wintersett Country Park, of this predominantly estuarine moth, suggests (perhaps temporary) resident populations.
2012 (CHF): Numbers have declined at its Spurn stronghold since the 1990s though there was an encouraging increase to 40 records in 2011. It is still recorded infrequently at West Melton and Wintersett but not as commonly as ten years ago.
