Main: (Hepialidae / Hepialinae)
03.001 [B&F: 0015] Orange Swift (Triodia sylvina) (Linnaeus, 1761)

 

Notes: Common, in gardens, woodland and rough grassland, and on roadside verges, downland and moorland, throughout Britain, including the Isles of Scilly, but excluding the Northern Isles. Wingspan male 32-39mm, female 36-48mm. Male brighter than female, but both distinguished from their congeners by the open dark-edged V-shaped diagonal lines on forewing, and the generally much later flight-time. Larva feeds within roots of docks, dandelions and other thick-rooted herbaceous plants, and Bracken, over-wintering twice.
