Davey, P., 2009: A frequently occurring species in England and Wales, but local elsewhere, the larva feeding on a variety of deciduous tree and shrub species. The female has very rudimentary wings. In Dorset, records of this species are few; admittedly trapping is rarely undertaken from mid-November onwards, but it is far more scarce than the Mottled Umber1935. Overall, it seems to be locally frequent in deciduous woodland and among scrub on chalky soil.
