Local in oak woodland throughout much of southern England and Wales, with records north to Yorkshire. In Hampshire there is a scattering of records generally away from the chalk and concentrated in the south and south-west of the county. Apart from one, possibly unconfirmed, record from 2013, not seen on the Island since Victorian times. 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.
