Nationally scarce (Na) in broad-leaved woodland throughout much of south-eastern England from Kent to Wiltshire, a priority species under the UK Biodiversity Action Plan, thought to be in decline due to changes in management of woodland, especially cessation of coppicing. In Hampshire first recorded in 1971 at Alice Holt, and only two records since; its true status remains a mystery, but it is obviously extremely rare. Not recorded from the Isle of Wight to date. Wingspan 28-31 mm. Main confusion species is Olive Crescent Trisateles emortualis, in which cross-line are light, not dark as in Clay Fan-foot. Larva feeds on Pedunculate Oak.
