History
The first records came from Sir Arthur Duncan (1909-84) who during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72).
 
During 1975-89 there were just over fifty records from five of the seven Rothamsted stations, Newton Stewart and Caerlaverock not recording it.
 
In the 1990s it was trapped regularly at Bargaly Lodge, Cally Woods (VC73), Kirkton and Durisdeer (VC72) with singles at Abbey Burn Foot, Stronord and Caerlaverock.
 
In the first decade of the 21st century, Cally Woods featured heavily again, with Carsfad at Dalry also trapping it regularly. Other sites during this period include Holm Wood, Stroan Wood, Closeburn, Old Torr, Forest Moor and Carsluith.
