Odezia atrataGeometridaeABH 70.13 B&F 1870
A day-flying moth of rough, often acidic grassland and hay-meadows where its foodplant Pignut grows. Often common where it occurs, it can be astonishingly local, persisting in isolated populations based on a couple of suitable fields. Widespread on parts of Exmoor - though not the whole of the area - in two separate areas of the Mendips, on the limestone hills north of Bath, and in a well-known but isolated population at Mount Fancy which appears to be its only site in the Blackdowns. The moth is occasionally reported from elsewhere.
