Sutton & Beaumont, 1989: First found in Yorkshire at Askham Bog (VC64) in 1950 then at Skipwith (VC61) (YNU, 1970), this species has now been found in several other localities in the County. Yorkshire is at the northern limit of its range (Skinner, 1984), so it will be interesting to see whether it continues to expand within the County.
2012 (CHF): This species has spread further across the county as far north as Teesside which is the northern limit on the east side of the country. Numbers are still growing with a peak of 156 records in 2011. More than half of the county records are from Spurn though the biggest concentrations are from inland wetland sites. Look for the characteristic headband (a dark line flanked by two paler lines) when viewed from the front (see photos) which is not shared with other confusion species such as Smoky Wainscot.
