Ichneutica purdii, the orange astelia wainscot,[2] is a moth of the family Noctuidae.

The deep wine coloured pupa is enclosed in a slight cocoon, with this being constructed below the soil, amongst debris or alternatively within a hollow stick.

[4] Fereday originally named the species Leucania purdii in honour of the collector of the type specimen.

[7] When fully grown the larvae are ocherous in colour with a pink flush with line markings but when ready to pupate these markings fade and the larvae take on a light golden hue with a rosy tinge to its rear segments.

[7] Fereday first described the adult male holotype specimen of this species as follows: Head and thorax dark pinkish-ochreous-yellow, darkest in front; abdomen paler and greyish at base.

Primaries above dark pinkish cedar colour, a dash of ochreous-yellow occupying the areolet between the submedian nervure and the third median nervule, the dash being very bright at the base and fading towards the posterior angle; a dash of the same colour commencing broadly in the middle of the discoidal cell, extending along the areolet between the first discoidal and lower subcostal nervules, and narrowing towards and vanishing near the exterior margin; a similar dash extending along two-thirds of the costa from the base of the wing; cilia, basal half ochreous-yellow, exterior whitish-ochreous.

Primaries below greyish-ochreous with a pinkish tinge, costal part more ochreous, exterior area more grey; cilia as above.

[9] I. purdii is endemic to New Zealand and can be found throughout the North, South and Stewart Islands.

[7] Once hatched the larvae are nocturnal, spending the day sheltering in the middle of their host plant.
