History 1860-2010

Only one record. Lennon (1863) had found it at Lochaber, close to Mabie Forest (VC73), but stated that it was not common.

The Moths of Great Britain and Ireland (1992) state it was formerly in southern Scotland but is in serious decline due to various changes in its habitat; it was widespread and locally common.
