Zelleria sphenota is a species of moth in the family Yponomeutidae. This species is endemic to New Zealand. It is classified as "At Risk, Declining'" by the Department of Conservation.
Taxonomy
[edit]This species was first described by Edward Meyrick in 1889 and named Hofmannia sphenota.[4][3] Meyrick used a specimen he collected from Riccarton Bush in August.[3][5] George Hudson discussed the species in his 1928 book The Butterflies and Moths of New Zealand using the name Zelleria sphenota.[6] The holotype specimen of this species is held at the Natural History Museum, London.[3] The genus level classification of this moth is currently regarded as unsatisfactory.[2] As such the species is also known as Zelleria (s.l.) sphenota.[2]
Description
[edit]The larvae of this species are green in colour.[7]
Meyrick described the male adult of the species as follows:
♂ 13mm. Head and antennae light ochreous-grey. Palpi grey. Thorax light ochreous. Abdomen whitish-ochreous. Legs fuscous, posterior pair ochreous-whitish. Forewings very elongate, very narrow parallel-sided, long-pointed, acute ; pale ochreous, thinly and irregularly sprinkled with dark fuscous and whitish ; basal half of costa dotted with black ; a moderately-broad ill-defined cloudy-white streak along inner margin from base to anal angle, pointed at extremities, interrupted at 2⁄3 by a small spot of ground-colour ; a cloudy inwardly-oblique dark fuscous mark at 1⁄3 from near costa to near inner margin: cilia ochreous-grey-whitish, round apex ochreous, with base white, a grey line, and three cloudy dark grey bars. Hindwings pale whitish-grey; cilia ochreous-grey-whitish.[4]
Distribution
[edit]This species is endemic to New Zealand.[2][8] This species has occurred in Taupō, Nelson, Marlborough Sounds, Mid Canterbury and Southland.[5] However it is likely extinct in the North Island.[5]
Behaviour and life cycle
[edit]Initially the larvae of this species are leaf miners but as they mature they mine the stems of their host plants, finally moving on to consuming the leaves and flowers.[7] They prepare for pupation by forming a white silk cocoon that is normally attached to the stem of their host plant.[7] This stage can last as little as ten days.[7] Adults emerge between the months of August and February.[7]
Host plants
[edit]_Tiegh._(AM_AK351706-6).jpg)
The host plants of this species are native leafy mistletoe.[5][9] These include the species Ileostylus micranthus, Peraxilla colensoi and P. tetrapetala.[10][7]
Conservation status
[edit]This moth is classified under the New Zealand Threat Classification system as being "At Risk, Declining".[1] This is as a result of the decline of its host species brought about through the browsing of possums.[5]
