Norfolk status Rare. The largest and most robust of the British Olethreutinae, this species is further distinguished from E. turbidana by the fasciculate-ciliate antennae and the lighter ochreous-brown general coloration of the forewing, which lacks an ocellus [Bradley].
Formerly found on the Yorkshire coast until 1910, Epiblema grandaevana is otherwise only known in the UK from a population in Leicestershire, although there have been several isolated records from West and East Suffolk up to 2004.
First Norfolk specimen found among leaves of coltsfoot on the soft-rock cliffs at Overstrand in 2012 (J. McGill, 15/07/12).
