[3] N. edwardsi larvae start off life green in colour but quickly change to brown.

[3] This species has only been seen in its natural habitat in December but it has been hypothesised that it may produce two broods in a season.

[4] When the larvae emerge from their eggs, they eat into the leaves or buds of their host, hiding from predators.

[4] They are low but fast flyers and constantly vibrate their wings to enable them to take off rapidly.

[3] This moth is classified under the New Zealand Threat Classification system as being Nationally Critical.
