History
The six people who went on the Field Meeting to Cairnsmore of Fleet on 2nd July 1881 as recorded in the Transactions, found the Grey Scalloped Bar resting next to a granite rock, which nearly went unnoticed due to its similarity to it. Gordon (1919) found it frequent on all moors in Wigtownshire. Larvae were also common on heather, with five on Low Moor on 4th March 1906, and ten on Whitedyke Moor, Corsemalzie area, on 28th May 1906. Earliest date was 14th May 1901.
 
In 1971 it was found at Culsharg and Loch Trool (VC73). During 1974-80 there were thirteen records from the Rothamsted station at Gatehouse of Fleet, with a single record from the Newton Stewart site in 1977, and another record from the Mabie Forest site in 1988.
 
On 6th June 1996 one was found at Torrs Warren (VC74), the only record in that decade; as were the two found on Corserig Hill, Kelloholm (VC72) in 2003, the only record for the first decade of the 21st century.
