The larvae consume parts of the seeds and fruits of tawa, tarairi and miro trees and are predated upon by the invasive to New Zealand house mouse.

They can be found having flown inside houses and have also been observed resting on fences or other human made structures during the day.

[3] George Hudson in his 1928 book The butterflies and moths of New Zealand discussed and illustrated this species under that name.

[6] The male lectotype, collected in Wellington by George Hudson, is held at the Natural History Museum, London.

Forewings elongate-triangular, costa gently arched, in♂ with very short and narrow basal fold, apex obtuse, termen rounded, rather oblique; purplish-bronzy-fuscous suffusedly mixed and strigulated with dark fuscous; costa obscurely pale-strigulated on posterior 2⁄3; a whitish or ochreous-whitish dot in disc at 2⁄3; two or three variable curved transverse series of small dark-fuscous spots or dots between this and termen : cilia fuscous, with darker line near base.

[7] They can be found inside houses due to this attraction and have also been observed resting on fences or other human made structures.
