History
Gordon (1919) stated it to be common locally at Alticry, Luce Bay, and at Corsemalzie on ivy at dusk. Earliest date was 16th June 1911. Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72).
During 1974-93 there were 65 records from six of the Rothamsted stations, Caerlaverock being the odd one out. From 1992 to 2010 there were 130 records recorded, regularly at Kirkton (VC72), with a wide scattering of records elsewhere, but only one was in Wigtownshire, at Forest Moor in 2006.

During 1985-88 specimens were caught at the Rothamsted station in Mabie Forest (VC73) that were totally different to the usual in that they were of a sandy ochreous brown colour. The records were discussed with Bernard Skinner but I can find out nothing else.
 
Life cycle
One generation. Overwinters as a fully grown larva during August to April, feeding until October, then forming a cocoon among plant debris, where it pupates in the spring.
 
Larval foodplants
Beech and oak withered leaves that have fallen to the ground.
 
Identification
The three cross-lines are more prominent than in the Common Fan-foot which has a whitish hind-wing.
 
Habitat
Broadleaved woodland, gardens and hedgerows.
