Taxonomy

This species was first described by Frances Walker in 1864 and named Aciptilus furcatalis. [4] Walker used specimens from Colonel Bolton collected in Auckland and T.R. Oxley collected in Nelson. [4] [2] In 1913 Edward Meyrick placed Aciptilus furcatalis into the genus Alucita. [5] In 1928 George Hudson followed Meyrick's placement discussing and illustrating this species in his 1928 publication The butterflies and moths of New Zealand. [6] In 1988 John S. Dugdale discussed this species under the name Pterophorus furcatalis. [2] In 1993 Cees Gielis discussed this species under the name Pterophorus furcatalis but placed it in a list where the species were regarded as having an uncertain status. [7] The lectotype specimen, collected by T. R. Oxley in Nelson, is held at the Natural History Museum, London. [2]

In 1928 Hudson illustrated the egg of this species. [6] Hudson subsequently described the larva of this species as follows:

The length of the larva when full-grown is about 38 inch. Very stout, rapidly tapering posteriorly; segments well defined. General colour rather pale green, darker on the back; the edges of the darker dorsal band edged with whitish. Head pale brown on the sides. Each segment furnished with a row of long, very stout, blackish-brown bristles and tufts of short whitish hairs near ventral surface. [8]

The larvae are slow moving and rest on the upper surface of the leaves of its food plants. [8]

Hudson also described the pupa as follows:

The pupa is about 516 inch long, stout, rapidly tapering towards extremity. Colour uniform grass green; integument polished, slightly and irregularly striated, with a row of impressions on each side of abdominal segments; limbs very faintly sculptured; no hairs or bristles. [8]

The larva prepares a large pad of silk on a support upon which the pupa is attached by the whole of its flattened ventral surface. [8]

Hudson described the adults of this species as follows:

The expansion of the wings is about 78 inch. The fore-wings are brown with 23 of the costa broadly edged with white, and a small white mark near the middle of the first plume. The hindwings are snow white. The head is white and the dorsal surface of the thorax and abdomen brown. All the cilia are white except a brown patch near the extremity of the second plume on the fore-wings. [6]

Some species have markings that are a darker shade of brown. [6] This species can possibly be confused with the brown streak form of P. monospilalis . [9] P. furcatalis but can be distinguished as the second plume is brown where as with P. monospilalis that second plume is white. [9] P. furcatalis also has a brown streak down the dorsal side of its abdomen which is also a distinguishing feature. [6]

Distribution

This species is endemic to New Zealand. [1] It can be found throughout the country including in the North, South and Stewart Islands. [6]

This species inhabits native scrub. Larvae feed on the leaves of species in the genus Olearia during the months of November and December. They then pupate amongst the old flowers and leaves of their host plant. Adults have been observed on the wing from August to September but are most common in January. It has been hypothesised that this species overwinters as an adult as it has been observed on the wing in late autumn and early winter. Adults are attracted to light.

<i>Charixena iridoxa</i> Species of moth

This species is endemic to New Zealand and has been observed in the North, South and Stewart Islands. The life cycle of this moth is at least two years in length with the larvae inhabiting the bulb of its host plants and mining the underside of its leaves. These mines have a distinctive zig-zag appearance and can be easily recognised when looked for on the host plants. The larvae pupate in a cocoon attached to the leaf and this stage takes place between February and August. The adult moths emerge in the early spring and are fast, day flying moths. Their larval hosts are plants in the genus Astelia and include Astelia fragrans and Astelia nervosa.

<i>Austramathes purpurea</i> Species of moth endemic to New Zealand

Austramathes purpurea is a species of moth in the family Noctuidae. It is endemic to New Zealand and can be found throughout the North and South Islands but has yet to be recorded at Stewart Island. It inhabits native forest. This species might possibly be confused with A. pessota, however this latter species does not have the purple hue to the forewings. The larvae of A. purpurea feed primarily on māhoe but have been recorded as feeding on, and have been reared on, narrow-leaved māhoe. The larvae pupate in a silken cocoon on moss covered ground. Adults can be found on the wing during the months of March to January but mainly occur during New Zealand's late autumn, winter, and spring. Light trapping may not be the most efficient technique for collecting this species.

<i>Physetica homoscia</i> Species of moth endemic to New Zealand

Physetica homoscia is a species of moth of the family Noctuidae. It is endemic to New Zealand and is found throughout New Zealand including in the Auckland Islands. This species inhabits places where its host plants are common and this includes costal dune habitat. It lives at a wide range of altitudes from sea-level up to at least 1750 m. The larvae of P. homoscia feed on Ozothamnus leptophyllus and Ozothamnus vauvilliersii. They are very active and drop to the ground when disturbed. Larvae are parasitised by a species of fly. This species pupates in the soil and the pupa life stage lasts for approximately 6 weeks. The adult moths are on the wing from September to June and are attracted to light. The adults of P. homoscia might possibly be confused with Ichneutica moderata however this latter species lacks the small white dots on the forewing veins of P. homoscia. Adults might also be confused with P. temperata but P. homoscia is significantly larger in size.

<i>Proteodes carnifex</i> Species of moth endemic to New Zealand

Proteodes carnifex is a species of moth in the family Depressariidae. It is endemic to New Zealand. Both the larvae and the adults of this species are variable in appearance. However the adults are normally easily identified as the outline is characteristic and the size is consistent. In appearance, adult moths mimic the leaves of their larval host plants. This species has been found near Wellington in the North Island, the tableland of Mount Arthur, in the Canterbury region, Arthur's Pass and at Lake Wakatipu in the South Island. The larval hosts of this species are southern beech trees particularly Nothofagus solandri var. solandari and Nothofagus solandri var. cliffortioides but larvae have also been found on Nothofagus fusca, Nothofagus truncata and Nothofagus menziesii. The female moth deposits her eggs individually on the underside of native beech tree leaves. Once hatched the larvae feed on those leaves through winter and spring and then pupate in January. The adult moth emerges from the pupa after fourteen days and is on the wing from January until April. They are day flying moths and are not attracted to light. Various insects parasitise the larvae of this moth including several species of wasp as well as flies including the endemic fly, Pales funesta.

<i>Tingena chloradelpha</i> Species of moth, endemic to New Zealand

Tingena chloradelpha is a species of moth in the family Oecophoridae. It is endemic to New Zealand and can be found in the North and South Islands. The larvae live underground forming silken tubes from which it feeds. It overwinters in these tubes and then pupates enclosed in a weak pale white silken cocoon. The adults of this species is variable in appearance both in the depth of colour as well as in its discal spots which may in some specimens be lacking. The adults are on the wing from October until the end of December and can be found inhabiting domestic gardens as well as cultivated land. They have been seen resting on window frames and can be found inside houses.

<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>Chrysorthenches drosochalca</i> Species of moth endemic to New Zealand
