Epiblema grandaevana (Great Bell) New to Norfolk

Epiblema grandaevana (Tortricidae) new to Norfolk

On Sunday 15th July 2012, James McGill found a specimen of the nationally very rare tortrix Epiblema grandaevana (B & F No. 1181) among leaves of coltsfoot on the soft-rock cliffs at Overstrand (TG2540). This is the largest British olethreutine tortrix, and is easily identified by its mottled brown fore wings and large size. The abundance of coltsfoot, a larval food-plant, on recent landslips at the site suggests that a colony is likely to be present. 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. The species is given a national status grading of pRDB2. - Andrew Duff.
