Resident. Common.
Flight period

Gordon (1919) found it common on tree trunks around Corsemalzie (VC74), with 12 being found between 14th and 29th February 1912. Larvae were found to be abundant on elms in the woods at Corsemalzie in June, 1906. Earliest date was 24th January 1911.
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Castlehill, Dumfries (all VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43.
At Irvine House Lodge, Auchenrivock a fine series were recorded early in 1974. Then, during 1974-92 five of the seven Rothamsted stations recorded 120 records between them, Caerlaverock and Newton Stewart not recording it.
From 1991 to 2010 the regular trapped sites at Bargaly Lodge, Kirkton, Cally Woods, Carsfad at Dalry, Durisdeer, Kirriereoch and Old Torr provided most of the eighty records with odd ones from various other sites.
Melanic form monacharia Staudinger
Cunningham (1950) recorded the first all-dark brown form at Tynron (VC72) on 14th February 1949. Another was caught in mid-March 1952 at the same site, both were by Sir Arthur Duncan, and both are at the National Museums Scotland. In 2009 three were noted at Kirriereoch (VC73) during February and March.
