Davey, P., 2009: A species of extensive deciduous woodland and parkland throughout Britain, the larva feeding nocturnally on various herbaceous plants and also on the buds of tree species during the spring. The adult is thought to aestivate during August. In Dorset, the moth is frequent and occasionally common in deciduous woodland. The dip in August is likely to reflect diminished activity due to aestivation. High nightly totals have included forty on 29 July 1992 at Durlston; this date is also mentioned in the Large Yellow Underwing2107 and Lesser Yellow Underwing2109 accounts. The extremely similar Noctua tirrenica occurs in southern Europe, and although there are no British records to date, it may be worth retaining the occasional yellow 'Broad-bordered Yellow Underwing' at times of immigration for closer inspection. Both species are deemed to exhibit immigrant behaviour abroad.
