History
Lennon (1863) stated it as common around the Dumfries area. Gordon (1919) found it common at light and at rest on tree trunks in Wigtownshire. They were very variable with large light specimens and small dark unicolorous ones, probably form fuscata Mosley. Earliest date was 18th February 1912. Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72).
 
During 1974-89 all seven Rothamsted stations recorded it with varying success amounting to 61 records. From 1992 to 2010 regular trapping at Kirkton, Durisdeer (VC72) and Cally Woods (VC73) provided most of the records, with a small scattering of records elsewhere in VCs 72 and 73; one record from Torrs Warren, Wigtownshire in this period.

Melanic for ab. fuscata Mosley
The first modern record to be noted was trapped on 11th April 2013 at Courance (VC72).
 
Life cycle
One generation. Overwinters as a pupa underground. Larvae present April to mid-June.
 
Larval foodplants
A wide variety of broadleaved trees and shrubs.
 
Identification
Brownish forewing in the male with a conspicuous row of black dots at the termen of both wings will help to identify it. The females are flightless.
 
Habitat
Mainly woodland, but also a wide variety of habitats.
