73.344 [B&F: 2108] Lunar Yellow Underwing (Noctua orbona) (Hufnagel, 1766)

 

Notes: Nationally scarce (Nb) in dry sandy areas, heaths and open woodland, discontinuously in parts of Britain, greatly declined, a priority species under the UK Biodiversity Action Plan. In Hampshire and on the Isle of Wight there is a strong colony at Porton Down, on the Wiltshire/Hampshire border, and the moth is recorded occasionally elsewhere. Wingspan 38-45 mm. Distinguished from Lesser Yellow Underwing N. comes by its narrower forewing and straighter costa, and by the presence of a black mark towards the apex. Distinguished from small examples of Large Yellow Underwing N. pronuba by the lack of discal spot on the hindwing. Larva feeds on various grasses and herbaceous plants, including Sheep's-fescue, Wavy Hair-grass, Cock's-foot, Common Couch, Reed Canary-grass, Meadow Buttercup, Creeping Cinquefoil, Cowslip and Chickweed.
