Species Account

Sutton & Beaumont, 1989: Not definitely recorded since Porritt (1883-86) when it had been reported from Barnsley, Doncaster (VC63), near Riccall, Selby (VC61) 'and I think also at Bishop's Wood', also at Sheffield in the 'old lists'.

2012 (CHF): One at Bishop Burton on 16.8.2004 was the first since Porritt's time. The following year Lancashire had its first record. This species is doing well to the south of us and is slowly moving north so we may see more records in years to come.
2021 (CHF): In Porritt’s time, Yorkshire was the northern limit for Black Arches. He described it as occurring at Barnsley, Doncaster, Riccall, Bishop Wood and in “old lists” at Sheffield. There are also some specimens in the Booth Museum at Brighton of adults bred from eggs taken near Middlesbrough in 1913, and this remains the most northerly record in the country. It then retreated southwards in the same pattern as Chocolate-tip to the Midlands and East Anglia, and evidence of spread to the north started about fifty years ago.
