Davey, P., 2009: A local woodland species in southern Britain, but scarcer further north, the larva feeding on various herbaceous plants before hibernation and the young foliage of shrubs and trees the following spring. In Dorset, the moth was always rare and any news of a surviving colony would be very welcome, as the last county record was more than twenty years ago. The majority of the moths were caught within old damp deciduous woodland on clay and sandy soils. The loss of old oak and birch woodland plus the blotting out of much of its preferred habitat during the last century from the spread of rhododendron and the block planting of conifers are possible factors behind its demise. It may be that the species hangs on still in the fragments of deciduous woodland that remain just to the south and east of Wareham, and on Brownsea Island. Recent initiatives to clear rhododendron from the Arne and the Brownsea Island nature reserves can only benefit colonies that might survive.
