Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Tynron (VC72). In the mid 1960s Pelham-Clinton found it at Caukerbush and Kirkbean (VC73).
 
During 1974-93 there were a hundred records recorded from all of the Rothamsted stations. On the Hensol Estate it was regulary recorded in the early 1980s.
 
From 1992 to 2010 there were three hundred records with more than half of them from the regular trapped sites at Kirkton, Durisdeer, Cally Woods and Kirkcudbright, with the rest from widely scattered sites across the region.
