Davey, P., 2009: A common species in southern Britain, the larva feeding on maple (Acer spp.), but more local further north where the larva feeds on alder (Alnus spp.). In Dorset, the moth is associated with deciduous woodland on chalky soil and here it is usually frequent. However, it is locally common in damp deciduous woodland on acid and clay soils, for example at Oakers Wood, Holt Forest, Trigon Ford and Arne Wood. In this biotype maple is largely absent, and alder or birch (Betula spp.) may host larvae at these sites. The moth has also also been recorded from coastal locations where there are few deciduous trees: St Alban's Head, Portland Bird Observatory and West Bexington. Recorded in 38 (95%) of 40 10k Squares. First Recorded in 1930. Last Recorded in 2019. (Data up to end 2019) |
