History
Douglas Robinson (1870-71) found it common at sugar during July on Almorness (VC73). K. J. Morton of Edinburgh (1900) whilst on a visit in July 1899 to Wigtownshire had found this species in the Monreith area. Gordon (1913) stated it to be generally distributed in Wigtownshire, sometimes common. It came to sugar from late June to early November in 1897. Earliest date was 17th June 1899.
 
William Evans received specimens from Mowat, the Killantringan lighthouse keeper during 1913-14 to aid his insect migration studies.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Tynron during 1951 and 1954 and also in Kirkmahoe parish in 1972.
 
During 1974-80 there were nineteen records from the four Galloway Rothamsted stations, with the twentieth from 1992 at Mabie Forest.
 
From 1992 to 2010 two thirds of the 130 records came from the regular trapped site at Kirkton, three from Wigtownshire, with the rest from scattered sites across VCs 72 and 73.
 
Life cycle
Two generations. Overwinters as a larva, during July to April, again, June to August.
 
Larval foodplants
A wide variety of herbaceous plants, including Beet, Carrot, Cabbage, Swede and Turnip, where it is regarded as a serious pest of these.
 
Identification
Forewing is very variable in colour, with a gleaming white hindwing. The kidney-mark, oval and central dart-mark are usually hollow-centred, which should help to identify it.
 
Habitat
A wide variety including agricultural land.
