[6] Alex Purdie describes the caterpillar of this species as: Length, at rest, about three- quarters of an inch.

Under-side with delicate whitish or yellowish longitudinal tracings, as on the upper side.

The junctions of the segments show yellowish or whitish rings when the larva contracts.

[7] While it is endemic to New Zealand,[8] the larvae have so far only been recorded feeding on exotic plant species: Nasturtium officinale, Plantago lanceolata, Trifolium ambiguum, Trifolium repens and Tropaeolum majus.

A recent study suggests this moth may be assisting with the pollination of avocado trees.
