History
Lennon (1863) stated it as very rare, but had found it on the Tinwald Downs (VC72).
 
The next four records occurred between 1990-92 in Mabie Forest (VC73) at the Rothamsted station during July, excepting one trapped with a Skinner at Bargaly Lodge (VC73). The first for Wigtownshire occurred in 1995 at Newton Stewart with one also at Kelton Mill (VC73) that year. Further records from Mabie Forest, Cally Woods (VC73) and Kelhead Flow (VC72) occurred during July 1997-99.
 
The first decade of the 21st century produced records from Closeburn, 2004, Kippford, 2005, Old Torr in 2011 and Minnigaff, 13th July 2012.
 
Has been recorded in all three vice-counties, but the majority are from Kirkcudbrightshire.
 
Life cycle
One generation. Overwinters as a larva during August to May, with pupation among plant debris.
 
Larval foodplants
Larval foodplant not known in the wild.
 
Identification
Status is unclear due to confusion with the unbanded form of Riband Wave. The subterminal line is prominent and curved towards the costa whereas it is sharply angled in Riband Wave.
 
Habitat
Open woodland, scrub and some gardens.
 
Recorders' notes
