Yorkshire Status: Very rare and very local. No recent record.
Sutton & Beaumont, 1989: There is one record of this species since Porritt (1883-86), from the Auckley area (VC63) as a larva in the late 1950s. No precise details are available but the authenticity of the specimen was vouched for by the late Mr A. H. Wright who was a close friend of the collector (per PS, Doncaster Mus.).
Species status (CHF, 2011): With the last in 1950, this species is unlikely to recolonise. The population in the south of England is healthy but it would need a major increase in population range to see it back in Yorkshire.
2012 (CHF): There is one other Yorkshire record which is mentioned in The Naturalist 1:255 as follows: Mr William Bowers of the Training College York, a young but indefatigable entomologist, during last midsummer's vacation collected in this neighbourhood amongst many others ... (list of larvae) ... Mr Bowers has taken splendid imagos of Boarmia Roboraria (Great Oak Beauty), N. Trepida (Great Prominent) and Stauropus fagi. Richard Hebson, Bailby Bank, Selby Nov 21 1864. It seems highly likely but unproven that the site of capture of this specimen must have been Bishop Wood.
