Lennon (1863) stated that it was rather common and that it had occurred at Terregles (VC72). Gordon (1913) had found it fairly common. It also came to sugar in the woods and on sugared posts on the moor at Corsemalzie, Wigtownshire. Earliest date was 6th September 1910.
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Tynron (VC72).
In 1977 there was one record from all of the Rothamsted stations, namely Gatehouse of Fleet, on 23rd September. On the Hensol Estate another was trapped on 8th September 1981.
