Davey, P., 2009: A very local species confined to south-east England, the larva feeding on field maple (Acer campestre). The moth is only known to occur in Chase Woods at the present time where large numbers of mature field maple trees grow on chalky soil, and in this locality it is frequent. Forty year-old records exist from Iwerne Minster, before the deciduous woodland in the area was replaced with conifer plantation in response to government incentives. The only other site where the moth has been found is Garston Wood, located a few miles to the east of Chase Woods. Coppicing within this wood carried out by the RSPB during the 1990s, reduced stocks of mature maple trees, and despite intensive light trapping in recent years, no further moths have been detected. Mature maple woodland appears to be a primary requirement for the moth, and further reduction in old woodland containing mature field maple trees in north-east Dorset will undoubtedly endanger this species further. Research to locate further colonies at Garston Wood is recommended plus the implementation of dedicated management plans for the species at Chase Woods.
