History
Somerville (1858) while on a visit to the Moffat area in August of that year had found it locally. Robinson-Douglas during 1874 had found it in the Castle Douglas area, while K. J. Morton had also located it near Monreith in July, 1899. Gordon (1919) had found it to be common and generally distributed in Wigtownshire. It was very numerous in meadows around Leswalt and Corsemalzie, (VC74). Earliest date was 14th June 1906.
 
Russell (1944) while staying at Gatehouse of Fleet during 1942-43 had found it locally. Sir Arthur Duncan (1909-84) during his lifetime had found it at Tynron. T. H. Ford found it at Sandyhills (VC73) in the mid-1970s. During 1976-89 there were nineteen records from four of the seven Rothamsted stations, all but four from Bridge of Dee.
 
From 1990 to 1997 there were five records: two from the Caerlaverock area and one from Powfoot (VC72), with Port o' Warren and Gutcher's Isle (VC73) adding the rest. One record in the first decade of the 21st century found on the Threave Estate in mid-August 2007.
