The first record came on 16th July 1999 when one was trapped at Float Bay, Wigtownshire. The following day, 75 were trapped at the Mull of Galloway (VC74), and from then to 2008, it has been found on Torrs Heughs at Sandyhills (1999) and Meikle Ross (2002), the only Kirkcudbrightshire records, with one more Dumfriesshire record from Kirkton, in 2006.

Since the original two records in VC74, a further 13 records have come from Wigtownshire during the period 1999-2008, all very adjacent to the coast.
