Taxonomy

This moth was first described by Edward Meyrick in 1881 using specimens collected in Hamilton in January.[2] He named the species Tortrix aerodana.[2] George Vernon Hudson discussed and illustrated this species in his 1928 book under the names Tortrix indigestana as well as T. aerodana.[1][3] In 1971 John S. Dugdale assigned T. aerodana to the genus Ericodesma.[4] The lectotype specimen is held at the Natural History Museum, London.[1]

Description

Meyrick described the moth as follows:

♂︎ ​4 3⁄4"-​5 1⁄4". Head, palpi, and thorax whitish-grey mixed with dark grey. Antennae dark fuscous-grey, sometimes with whitish annulations. Abdomen light grey, anal tuft whitish. Legs grey-whitish, anterior and middle tibiae and tarsi suffused with dark fuscous. Forewings narrow, costa slightly arched, hindmargin very obliquely rounded ; dark grey, irrorated with ashy-whitish and black scales ; sometimes there is a distinct ochreous slender oblique fascia from middle of costa to inner margin before anal angle, and costal spot at three-fourths, but these are often imperceptible ; cilia whitish-grey mixed with darker. Hindwings dark grey ; cilia paler, with a dark grey line near base. ♀︎ ​6 1⁄2"-7". Head, etcetera, as in male. Abdomen whitish-ochreous. Forewings with costa somewhat more arched towards base, hindmargin very oblique ; paler than in male, without trace of fascia : cilia whitish. Hindwings whitish, posteriorly whitish-grey ; cilia white, with a faint grey line near base.[2]

Distribution

This species is endemic to New Zealand.[5][6] The species can be found in Waikato, Bay of Plenty, Taupo, Taranaki, Whanganui, Wellington, Marlborough & Marlborough Sounds, Kaikoura, Mid Canterbury.[7]

Biology, behaviour and habitat

Adults are on wing from October to January.[8] Adult moths are active at twilight.[9] E. areodana inhabits active sand dunes.[10]

Host species

The larvae feed on Pimelea prostrata.[8]

Conservation Status

This species has been classified as having the "At Risk, Declining" conservation status under the New Zealand Threat Classification System.[9] The survival of this moth is dependent upon the survival of it host plants.[7] These are under threat as a result of habitat loss.[7] The moth and its host plant is also under thread by sea spruge.[11]
