Chrysorthenches phyllocladi is a species of moth in the family Plutellidae.^[2] It was first described by John S. Dugdale in 1996. It is endemic to New Zealand and has been observed in both the North and South Islands. The larvae of this species feed on Phyllocladus alpinus . Adults have been observed on the wing in February, April and November.

Taxonomy

This species was first described by John S. Dugdale in 1996.^[3] The female holotype, collected by Dugdale at Governors Bush in the Mackenzie District, is held at the New Zealand Arthropod Collection.^[3]

Description

Dugdale described the adults of this species as follows:

Wing span 11.5-14.0 mm. Colour pattern: head white; antennal scape, pedicel, and proximal 4 flagellomeres broadly white dorsally. Tegulae purple; mesonotum grey or brownish white in ♂, pure white in ♀. Forewing coppery purple, reflecting violet on most of costal half; white markings broader in ♀ than in ♂; basal band oblique, not meeting costa, often present as a patch centred on vein CuP, curving to dorsum (♀) or an arcuate oval (♂); anal angle (base of dorsum) broadly (♀) or narrowly (♂) white; antemedian band oblique, often with a central fine line of black scales; median band present as an obscurely divided white patch ending on discal cell; postmedian band interrupted on discal cell by a dark violet-reflecting dot; terminal area of wing largely white-scaled on costal half. Metanotum, hindwings, and abdomen dark to pale grey-scaled; thorax and abdominal venter paler-scaled. Male hindwing with a long axillary tuft extending to at least half abdomen length. Middle tibia dark, with a single white ring at mid-length.^[3]

This species can be distinguished from similar appearing moths by the pattern of white bands on its forewings, the forewing ground colour of reflective violet, and the long axillary tuft at the base of the hindwing of the male of the species.^[3]

Distribution

This species is endemic to New Zealand and is found in the North and South Islands.^[1] Along with the type locality this species has been observed in the Taupo, Hawkes Bay, North Canterbury, Westland, Dunedin, Central Otago and Southland regions.^[3]

Behaviour

Adult moths have been collected in February, April, and November, although Dugdale hypothesised that the November specimen was an overwintering adult.^[3]

Hosts

The larval host of this species is Phyllocladus alpinus .^[3]

DNA analysis

In 2020 this species along with the other species in the genus Chrysorthenches had their DNA and morphological characters studied.^[4]

Zealandopterix zonodoxa is a moth of the family Micropterigidae. It endemic to New Zealand and is found from the Hawkes Bay north as well as on Poor Knights, Little Barrier and Great Barrier Islands. It is the smallest micropterigid in New Zealand and the shiny white markings on the forewing of this species are variable. It is a day flying moth, but has been collected using UV light. Adults are on the wing from September to March and the species has been witnessed visiting the flowers of Nikau and Cordyline pumilio in large numbers. It inhabits a wide variety of moist indigenous forest but is associated with forests in which podocarps are common. Larvae have been sieved from rotten wood on the floor of a mixed podocarp/broadleaf forest or extracted from moss or from bryophytes.

Asterivora albifasciata is a species of moth in the family Choreutidae. It is endemic to New Zealand and has been observed on both the North and South Islands. The adults of this species are on the wing in December and January. Larvae of this species have been raised on Celmisia brevifolia.

Adults of this species are on the wing in February and flies rapidly in sunshine.

Asaphodes albalineata is a species of moth in the family Geometridae. It is endemic to New Zealand and has been observed on Stewart Island / Rakiura.

Hierodoris frigida is a moth of the family Oecophoridae. It is endemic to New Zealand and is only found in the South Island. This species is found in two parts of that island, the Nelson/Tasman area and the Mackenzie, Otago and Dunedin areas in the southern part of the island. Although similar to H. iophanes this species can be distinguished as H. frigida has white bands on its forewings and the metallic coloured areas differ in placement. Segment 2 on the labial palp is entirely yellow and enables this species to be distinguished from the similar appearing species H. polita and H. torrida. Larvae have been collected amongst leaf litter from beneath species within the genus Thymus. It prefers open and shrubland habitats and adult moths have been observed flying close to the soil underneath Leptospermum scrub.
