ID pointers: As the name suggest, a black head and thorax. A rather broad forewing, whitish in the male and whitish with a pinkish hue in the female, with brownish or greyish suffusion. Greyish or black at the base and a brown and blackish irregular cross-band at about a half, being narrowly interrupted near the costa. A mix of blackish, purple/blue and brown markings at the termen and apex.
A good guide for the other three “lookalikes” – N.dubitana Head & Palps – White / Thorax – Blackish
N.hybridella Head & Palps White / Thorax – White
N.molliculana Head & Palps – Brown / Thorax – variable mix of White.
