Norfolk status
Rare.
Mainly coastal and often common in open dune areas. Local and rare inland.

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 and the coastal form of B. affinis will require Gen. Det.
