History

The first for the region was when F. W. Smith caught one on 28th June 1943 at Closeburn (E. W. Classey, The Entomologists’ Gazette 1: 51).

Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Tynron.

During 1975-82 there were two records from Caerlaverock, three from Waterside Mains at Keir, and a single from Bridge of Dee Rothamsted stations. Then, from 1985 to 1993, thirty eight records were recorded from the Mabie Forest station.

Confirmed records from 1997 to 2010 occurred at Kirkton and Durisdeer (VC72), Carruchan Moss and Mersehead RSPB (VC73).
