It inhabits open mountain sides and adults are on the wing in November to January.

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

The forewings are elongate, posteriorly dilated, the costa gently arched, the apex obtuse, the termen bowed and oblique.

They are greyish-bronze, irregularly irrorated with white, especially towards the costa and on a terminal band.

[1][7] It is found in the southern half of the South Island and has been observed in the Hunter Mountains, the Hump range in Fiordland and at Bold Peak.
