The larva and pupa of this species is currently unknown but the adults are on the wing in February, October and November.

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

[2] The female lectotype, collected by George Hudson at Mount Taranaki in February, is held at the Natural History Museum, London.

Forewings elongate, costa moderately arched, apex pointed, termen slightly sinuate, rather strongly oblique; bright shining bronze : markings shining white; a streak along fold from base to 2⁄3; an oblique streak from costa before middle to fold; an oblique streak from costa beyond middle not reaching half across wing, and a slightly oblique streak from dorsum before tornus, their apices connected by a purple black mark; a purplish-black dot on tornus; three small wedge-shaped spots on costa posteriorly; three or four small marks or dots along termen, one below middle forming an erect strigula : cilia grey, basal half bronzy, round apex with three or four white bars.

[1][6] As well as the type locality this species has been observed at the Motueka Valley, Arthur's Pass and Christchurch.
