The life history of this species is in need of further investigation as sources differ about what plants host the larvae.

It was first described by Francis Walker in 1862 using specimens collected by A. Sinclair in Auckland and originally named Larentia semisignata.

Fore wings with several denticulated blackish lines, some of which are most conspicuous on the veins, where they form black points; middle space without lines, containing the black transverse elongated discal point; interior, exterior and submarginal lines formed by whitish points on the veins; marginal lunules black; costa convex; exterior border hardly convex.

[9] However this species normally has orange scaling present on its forewings and its wing veins have black and white patches.

[11][12] These inconsistencies have resulted in Robert Hoare stating that further investigations into the life history of this species is needed.

[9] The adult moths have been observed visiting and likely feeding from the flowers of Hoheria lyallii, Olearia virgata andVeronica salicifolia.
