Yorkshire Status: Uncommon and fairly widespread resident.

Sutton & Beaumont, 1989: Probably widespread and frequent in all five vice-counties. However, this is a species which comes to sugar more readily than light and records are rather few in VC61 and VC65. Only reported as common at Harmby, VC65 (FBS) and Sheffield, VC63, where Garland (1979) states it to be abundant in gardens.

2012 (CHF): Widespread and fairly common across the county, particularly in upland areas in the west and the north-east. Numbers and distribution have not altered recently. This species has two broods to the south of us but there is little evidence of this happening in Yorkshire yet.

Recorded in 157 (79%) of 200 10k Squares.
First Recorded in 1879.
Last Recorded in 2022.
