History
Firstly, there were two records in 1975, one in August near Stranraer, the other in a Rothamsted trap at Caerlaverock WWT (Colley, 1981). During 1996, seven were found, five at Mersehead RSPB, two at Kirkton (VC72). In 2000 one was trapped at Cally Woods (VC73), with a further two trapped singly at Kirkton in August and October, 2006, and an earlier male at Kippford in June, 2006, see photo. This is the only specimen where the sex was recorded.
