Wingspan about 10 mm. The only all-white member of the Opostegidae in Britain, it is fairly easy to identify due to its very large eye caps.
It inhabits open areas where the suspected foodplant, Sheep's Sorrel (Rumex acetosella) occurs, although the early stages have yet to be found in Britain.
Can be attracted to light during its flight period from June to early August.
Distributed widely but locally throughout much of Britain. In the Butterfly Conservations Microlepidoptera Report 2011 this species was classified as local.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
