History 1860-2010
Douglas Robinson (1870-71) had only one to record which he found at flowers in August, 1870 on Almorness (VC73). Buchanan White of Perth (1895) listed it as occurring in Colvend and Southwick parishes (VC73).
David Cunningham on 31st July 1951 had also found it at Closeburn, it was an addition to the Dumfriesshire list. Sir Arthur Duncan (1909-84) during his lifetime had found it at Tynron and Castlehill, Dumfries (all VC72).
Although five of the seven Rothamsted stations recorded it, Waterside Mains and Mabie Forest recorded many records, with Gatehouse of Fleet, Caerlaverock and Bridge of Dee managing just a handul of records between them. During 1992-2010 Kirkton, Durisdeer (VC72), Mersehead RSPB and Cally Woods (VC73) with regular trapping recorded it many times. It was also recorded from many widespread sites proving it to be very common.
