Local in oak woodland throughout much of southern England and Wales, with records north to Yorkshire. In Hampshire there is a scattering of records along the M27 and M3 corridors, and although evidently rare, it is perhaps under-recorded elsewhere. Not recorded from the Isle of Wight since 1900. Wingspan 17-19 mm. Similar to Y. alpella, but generally darker with more obvious fasciae (MBGBI Vol 3). Larva feeds on Oak, beneath a silken web, over-wintering as an egg.
