History
The earliest notification of this species is published in Stephens (1829) with the Rev. William Little recording it at Raehills (VC72).
 
Gordon (1919) found it abundant on the moors around Corsemalzie (VC74). He also found it on tree trunks, being very variable, with melanic forms occurring. Earliest date was 14th June 1906, with the latest 1st October 1897.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43.
 
It was the early 1970s before it appeared again, Silver Flowe, Caldons, Stroan Loch and Auchenrivock. During 1974-93 it was recorded from all seven Rothamsted stations, with varying totals from each. From 1993 to 2010 Cally Woods (VC73) and Durisdeer (VC72) have recorded most records, with a wide scattering of records from other sites across the region, proving it to be one of our commonest geometrids.
 
Life cycle
One generation. Overwinters as an egg. Larvae are present April to June, with pupation among plant debris.
 
Larval foodplants
Birches, Sallow, heathers and Bilberry.
 
Identification
A widespread species that is more variable in its markings in Scotland than in the south. On the hindwing the central cross-line usually has a sharp point.
 
Habitat
Woodland, scrub, heathland, moorland and other habitats.
 
Recorders' notes
Care needed in separating from Common Marbled Carpet from July onwards when it emerges.
