Main: (Ypsolophidae / Ypsolophinae)
17.006 [B&F: 0456] Ypsolopha horridella (Treitschke, 1835)


Nationally scarce (Nb) in open woodland and gardens throughout southern England and northern Wales. Barely annual in Hampshire, where recorded widely, but only regular on the coast in the south-east of the county; very rare on the Isle of Wight. Wingspan 16-21 mm. Positioning and size of scale tufts on dorsum, and fuscous colouring distinguish Y. horridella from its congeners. Larva feeds on Apple and Blackthorn, beneath a silken web, over-wintering as an egg.
