History
One historical record which Lennon (1863) recorded from Tinwald Downs (VC72) but he stated that it was not common.
 
The next record was not until the mid-1970s when T. H. Ford found it at Sandyhills (VC73), and in 1979 it appeared at Laurieston Hall. Just one record in the 1980s, E. F. Hancock recording it from Kilsture Forest (VC74).
 
But from 1995 to 2010, apart from 2004, it has been recorded annually, averaging under a handful of records per year, all within Dumfriesshire and Kirkcudbrightshire.

Subspecies S. f. scotica Cockayne, 1951
We have two records of this smaller, darker and more strongly marked form, both in early August 2011 from Dumfriesshire.
 
Life cycle
One generation. Overwinters as a fully grown larva, with pupation in loose earth.
 
Larval foodplants
Larvae feed on bedstraws and vetches.
 
Identification
It is very similar to the Lesser Cream Wave but slightly larger with more pointed forewings. It also has a differing habitat to that species, liking broadleaved woodland and hedgerows where it can be disturbed during the day. The flight period is slightly earlier too, being from early June to early August.
 
Habitat
Woodland, scrub, hedgerows and gardens.
 
Recorders' notes
Care should be taken in separating this species from the Lesser Cream Wave. Also, beware of the male Smoky Wave when anticipating form scotica.
