Taxonomy

This species was first described by John S. Dugdale in 1996. [3] The male holotype specimen, collected as a larva at the Lewis Pass summit and raised to maturity, is held at the New Zealand Arthropod Collection. [3]

Description

Illustration of C. halocarpi.

The larva of this species has a green body and brown head. [3] The pupa can be found within a silk cocoon covered in frass. [3] Dugdale described the adults of this species as follows:

Wing span 8.5—10.5 mm. Colour pattern: head dark-scaled, with frons and vertex purple-reflecting; antennal scape dark-scaled, pedicel and proximal 4 flagellomeres black dorsally, other flagellomeres black and white-scaled; gular tuft grey. Mesothorax and forewings dark brown, strongly purple-reflecting. Forewings banded with speckled white markings: basal band oblique, not reaching costa in ♂, reaching costa and wider and less peppered (more obvious) in ♀; antemedian band parallel to basal band, with dull purple speckling, and edged irregularly in dark, strongly purple reflecting scales; postmedian band interrupted by dark purple scales discally; vein CuP with strong purple-reflecting patches at half length and at apex (just before tornus); terminal part of wing with irregular small patches of white scales. Thoracic scaling, hindwings and abdomen dark grey. Middle tibia dark, with white rings absent or faint. [3]

Specimens of this species has been confused with specimens of C. drosochalca , but can be distinguished as C. halocarpi has a purple shaded ground colour to its forewings, has dark throat scales in comparison to the white in C. drosochalca and lacks the white rings on the middle tibia which can be seen in C. drosochalca. [3]

Larvae have been sieved from rotten wood on the floor of a mixed podocarp/broadleaf forest or extracted from moss or from bryophytes.

<i>Hierodoris atychioides</i> Species of moth endemic to New Zealand

Hierodoris atychioides is a moth of the family Oecophoridae. It was described by Arthur Gardiner Butler in 1877. The female holotype specimen held at the Natural History Museum, London. This species is endemic to New Zealand, and can be found in the North, South and Stewart Islands. The larvae form webs of silk attached to frass and leaves on their hosts in which they shelter, often in the company of other larvae in their species. Their feeding habits have not been observed in detail but Hoare hypothesises the larvae may feed on dead or dying leaves. The larvae feed on a wide range of trees and shrubs, including Dacrydium cupressinum, Prumnopitys taxifolia, Dacrycarpus dacrydioides, Libocedrus bidwillii, Cupressus macrocarpa, Leptospermum scoparium, Kunzea ericoides, Ozothamnus leptophyllus, Abies, Picea, Pinus and Thuja species. Although they are regarded as a pest of exotic forests in New Zealand, the economic damage the larvae cause is minimal and they tend to be controlled only by their natural enemies. Larval enemies include the parasitic flies Trigonospila brevifacies and Pales funesta as well as parasitic wasps including Xanthopimpla rhopaloceros. The adult moths are day flying and are most common during the months of December and January. This species is variable in appearance as larvae, pupa and as adults, and it has been hypothesised that it is in the process of speciation.

<i>Hierodoris frigida</i> Species of moth endemic to New Zealand

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.

They are on the wing from November until January. This species is regarded as being uncommon.

<i>Chalastra aristarcha</i> Species of moth, endemic to New Zealand

Chalastra aristarcha, the silver fern moth, is a moth of the family Geometridae. This species was first described by Edward Meyrick in 1892. It is endemic to New Zealand and is found in the North Island. This species inhabits dense native forest. The larvae feed on the species host plant, the Silver fern, during spring. This species then pupates on top of leaf litter or moss on the ground. The pupation state lasts for approximately 6 weeks. Adult moths are on the wing from October until April but can sometimes also be seen during the winter months. Adults can be disturbed from silver ferns during the day or are seen on the wing at night particularly at Metrosideros perforata when in flower. Adults are attracted to light. It has been hypothesised that the range of C. aristarcha has restricted as a result of urban development and land conversion of its habitat.

<i>Trachypepla contritella</i> Species of moth endemic to New Zealand
