Lewis at Broken River, Canterbury and named Hydriomena expolita.[3][4]George Hudson discussed and illustrated this species in his 1928 book The Butterflies and Moths of New Zealand under the same name.[5] In 1987 Robin C. Craw placed this species within the genus Helastia.[2] The holotype specimen is held at the New Zealand Arthropod Collection.[4]Description[edit]Philpott described the species as follows:       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4\u2642\ufe0e. 30 mm. Head, palpi, and antennae purplish-grey. Thorax fuscous-brown mixed with grey. Abdomen fuscous-grey with some reddish scales laterally. Forewings moderate, triangular, costa moderately arched, apex subacute, termen sinuate, oblique\u00a0; whitish-grey with faint purplish tinge\u00a0; markings dark purplish-fuscous\u00a0; basal line thick, evenly curved, projecting angularly at middle\u00a0; anterior margin of median band inwardly oblique beneath costa at 1\u20443, thence broadly excurved to dorsum at 1\u20444\u00a0; posterior margin from 2\u20443 costa to 3\u20444 dorsum, with strong broad apically-indented projection at middle\u00a0; traces of a thin waved white subterminal line\u00a0; an oblique suffused purplish-fuscous fascia from apex\u00a0: cilia grey, obscurely barred with fuscous, tips whitish. Hindwings elongate, termen angularly projecting at middle\u00a0; purplish-grey\u00a0; basal half darker, being marked off by a median fascia parallel to termen\u00a0: cilia as in forewings. Undersides\u00a0: Forewings ochreous-reddish with the upper markings faintly reproduced\u00a0; hindwings ochreous-reddish, terminal half suffused with whitish.[3]Distribution[edit]This species is endemic to New Zealand.[6][1] It occurs in Buller, Marlborough, North Canterbury and Mid Canterbury.[2]Biology and lifecycle[edit]Very little is known about the biology of H. expolita.[7]Host species and habitat[edit]This species prefers short tussock grassland habitat in montane to subalpine zones.[2][8] The host species for the larvae of H. expolita is unknown.[9] It has been hypothesised the larvae of H. expolita feed on the flowers of Helichrysum species and then feed on mosses, lichens or shrubs growing nearby.[10]Conservation status[edit]This moth is classified under the New Zealand Threat Classification system as being “At Risk, Relict”.[11] The decline in the area and quality of this species habitat is one of the factors putting this species at risk.[7]References[edit]^ a b “Helastia expolita (Philpott, 1917)”. www.nzor.org.nz.
