History

The first record was from Sir Arthur Duncan (1909-84) who found it in October 1946, at Castlehill, Dumfries (VC72). The second was trapped at Irvine House Lodge, Auchenrivock (VC72) in October 1973.

During 1975-80 with the Rothamsted stations running, it was trapped mostly at Caerlaverock (VC72), but small numbers of records also came from Bridge of Dee (VC73) and Waterside Mains at Keir (VC72). The Mabie Forest site was set up later and recorded it in 1990 and 1992.

From 1992 to 2009 it only occurred at three sites, twice at Caerlaverock, once at Old Torr (VC73), with the rest from Kirkton, thirty four records in an eight-year span from 1992.
