Davey, P., 2009: A species confined to south-east England plus a few sites further north and west, but absent in Scotland, the larva feeding on horse chestnut (Aesculus hippocastanum), sycamore (Acer pseudoplatanus), maple (Acer campestre) and occasionally other deciduous trees. In Dorset, the moth is widespread but at low density and rarely frequent. It is found wherever its primary foodplants grow, whether in deciduous woods, plantations, open hedgerow situations or in towns and villages. The larva has been found feeding on sallow (Salix spp.) at Whitesheet, a locality where none of the primary foodplant species occur. Although the moth is single brooded in mid-summer in the UK, a separate single brood is suspected from mid-May with the main brood on the wing between late-June and early August.
