History
Lennon (1863) stated that it was not common, but that it had occurred at Dalskairth (VC73). Gordon (1913) took one at sugar on 16th September 1897 at Corsemalzie, while Mr. Henderson, keeper at Mull of Galloway Lighthouse had caught two in 1909 (Miss D. Jackson).
 
Cunningham (1950) in the Transactions had a specimen come to sugar in Mabie Forest (VC73) on 16th September 1949. Sir Arthur Duncan during his lifetime (1909-81) had caught it twice at Closeburn (VC72). Only one was caught at the Rothamsted stations and that was at Waterside Mains (VC72) on 11th September 1982.
 
Further records followed from Kirkton and Mersehead RSPB during the latter part of the 1990s, followed by the only modern record for Wigtownshire being trapped at Milton Point on 24th September 2000.
 
The first decade of the 21st century provided 14 records, mainly VC73.
 
Life cycle
A late autumn visitor here.
 
Larval foodplants

Identification
The 'Mohican-style' crest on the head, coupled with the mother-of-pearl like translucent underwing will determine the species.
 
Habitat
Generally occurs in coastal areas.
