Distribution


Imago

Wingspan 18–23 mm. A fairly variable species, though usually showing a pale blotch on the dorsal area, sometimes edged with darker.
The nominate and other fasciate forms of E. brunnichana may be confused with some forms of Epinotia solandriana, which dorsal blotch is triangular and in Epinotia brunnichiana it is subquadrate or trapezoid.
Also in E. brunnichiana the outer edge of the subbasal fascia is less oblique dorsally.
