Sutton & Beaumont, 1989: This species was only recently discovered in Britain (Skinner, 1984), although it may have been an unnoticed resident for some time, being difficult to distinguish from C. rectangulata (Linnaeus). In Yorkshire it was first found by P. Q. Winter in 1975 and there have been several records since. It is probably still overlooked as an adult, being most easily identified in the larval stage.
2012 (CHF): Still local in the county and not recorded every year. Uncommon in VC63 and 65 with most records from the centre of the county. Take care to separate this species from the much commoner Green Pug. Sloe Pug fades rapidly and loses its green colour.
