[4] George Hudson discussed and illustrated this species in his 1928 book The Butterflies and Moths of New Zealand.

[2] The larvae of this species are large, angular and green coloured with thin red and white lines.

Thorax with moderate bifid anterior and posterior crest; green, with black irregular V-shaped mark, the apex towards head.

Hind wings pale greenish-yellow, with brownish suffusion on apical portion; an irregular line at 2⁄3, and discal spot of same colour.

[9] The larvae are bright green coloured and as a result are well camouflaged when feeding on their host species.

[10] This moth is classified under the New Zealand Threat Classification system as being "At Risk, Relict".

[8] The elimination of the host plants of this species has resulted in their extinction from sites in New Zealand.
