Genus:Depressaria
Species:douglasella
Authority:Stainton, 1849

Nationally scarce (Nb) in grassland and waste ground throughout much of England. In Hampshire and on the Isle of Wight recorded from a handful of sites, and quite rare in North Hampshire. Wingspan 17-21 mm. The main confusion species are D. pulcherrimella, in which the angle made by the pale fascia on the forewing forms a right-angle (obtusely angled in A, douglasella), and D. sordidatella, which differs in the slightly glossy, less heavily marked forewing and the darker head, thorax and tegulae (MBGBI Vol 4 part 1). Larva feeds on Wild Carrot, Wild Parsnip and Upright Hedge-parsley, living between leaves spun together with silk.
