Morley’s Final Catalogue: At present almost confined with us to the Breck : Santon Downham before 1890 (Norgate): near Thetford (Harwood); at light in Tuddenham Hall, in that village, during late August 1902 (Mly). Several at Minsmere in Sept. 1928, and one on Sutton Heath in Aug. 1933 (Bp.).

Recent Status: A scarce species in Suffolk primarily associated with dry sandy locations such as heathland that is recorded across the county.

Life Style: A single brooded species flying late in the summer peaking in late August or early September. The larvae are believed to feed on the Wavy Hair Grass, Deschampsia flexuosa.

Identification: Crambus hamella is one of the easier Crambus species to identify. The complete central white streak on the forewing has a prominent spur, does not touch the costa and after widening evenly from the base narrows only when close to the sub-terminal line that is does not quite reach.
