Norfolk status Rare. Mainly coastal and often common in open dune areas. Local and rare inland.
2002 records at Holme Dunes.
Differs from the other black Bryotropha ( B. affinis and B. similis ) by the conspicuous clear white costal and tornal patches contrasting with the very dark forewing.
Specimens found in coastal areas are often not as dark, with a grey form (f. portlandicella) and very pale / white form (f. mundella). Very light coastal forms can be confused with the coastal form of B. affinis (Gen. Det. Required)
