Ichneutica naufraga is a moth of the family Noctuidae. [1] [2] This species is endemic to New Zealand. It is only found on Big South Cape Island. The host of I. naufraga larvae is Poa foliosa, upon which the larvae feed at night. Adult moths have been recorded on the wing in November. This species can be distinguished from the visually similar I. mutans as both the male and female of the former species lack the distinctive dark marking that can be found on the forewings of I. mutans. The female I. naufraga is coloured a brown shade as opposed to the grey I. mutans and the male I. naufraga has longer antenna pectinations.

Taxonomy

I. naufraga was first described by Robert Hoare in 2019. [2] The male holotype specimen was collected by J. S. Dugdale in November 1968 and is held by the New Zealand Arthropod Collection. [2] Hoare justified erecting this species based on the difference in the forewing appearance, antenna and genitals of adults of the species. [2] This species has not been collected since 1968. [2]

Description

The wingspan of the adult male of this species is between 35 and 37 mm and for the adult female is between 35 and 41 mm. [2] I. naufraga is similar in appearance to I. mutans. It can be distinguished from that species as the male I. naufraga has longer pectinations that also reach further along the antennae, the female is coloured a brown rather than a grey shade and both the male and female lack a dark marking that can be found on the forewings of the I. mutans. [2]

Distribution

This species is endemic to New Zealand and is only found on the Big South Cape Island, off Stewart Island. [3] [2]

Behaviour

Adults of I. naufraga are on the wing in November but may also be present in surrounding months as no sampling has been done outside of November. [2] This species is attracted to light. [2]

Ichneutica maya is a moth of the family Noctuidae. It is endemic to New Zealand. It is found in the mountains in southern half of the North Island and in the South Island. I. maya is a distinctively coloured and patterned moth and as such is unlikely to be confused with similar species. I. maya can be found in the southern half of the North Island down through the South Island. This species can be found in alpine to subalpine zones with high rainfall but in Southland this species can be found down to sea level. This life history in the wild is unknown, nor has its larval host species been confirmed. Adults are on the wing from December to March and are attracted to sugar and light traps.

<i>Ichneutica nullifera</i> Species of moth

Ichneutica nullifera is a moth of the family Noctuidae. This species is endemic to New Zealand and can be found in the Tongariro National Park, along the Wellington coast and throughout the South Island. The adults are large and the forewing of adults can vary in colour from pale fawn to dark grey. The larvae are coloured a bright yellow-brown with a paler underside. The larval host species are in the genus Aciphylla and as a result the adult moths are often found in habitat dominated by species in this genus. Adults are on the wing from November to early April and are sometimes attracted to light.

<i>Ichneutica pagaia</i> Species of moth

Ichneutica pagaia is a moth of the family Noctuidae. I. pagaia is endemic to New Zealand and can only be found on the Snares Islands. This species is unlikely to be confused with moths with a similar appearance as it is the only noctuid found in the Snares Islands. Its preferred habitat is tussock grasslands and the hosts for its larvae are likely Poa astonii and Poa tennantiana. Adults of this species are on the wing from November to February.

<i>Ichneutica petrograpta</i> Species of moth

Ichneutica petrograpta is a moth of the family Noctuidae. This species is endemic to New Zealand where it is found in the southwest districts of the South Island, including Westland, Otago Lakes and Fiordland. It is very similar in appearance to I. mutans.

<i>Ichneutica acontistis</i> Species of moth

Ichneutica acontistis is a moth of the family Noctuidae. It is endemic to New Zealand and is found only in the South Island, mainly on the eastern side although not in the Nelson district. This species is similar in appearance to I. paraxysta,I. stulta and I. toroneura. I. acontistis is unlikely to be confused with I. paraxysta as the later is only found in the North Island. I. acontistis can be distinguished from I. stulta as the latter species has a strongly curved forewing edge where as I. acontistis' is straight. I. acontistis can be distinguished from I. toroneura as the former has a dark stroke of colour starting from the base of the forewing that I. toroneura lacks. I. acontistis inhabits tussock grasslands and the larvae of this species feed on species of grass found in the genera Poa, Elymus and Rytidosperma. It pupates under rocks and adults are on the wing from September to January. I. acontistis are attracted to light.

<i>Ichneutica micrastra</i> Species of moth

Ichneutica micrastra is a moth of the family Noctuidae. It is endemic to New Zealand. This species has been found only in the North Island and has been collected in the Northland, Auckland, Whanganui and Wellington regions. The preferred habitat of this species is wetlands and heathlands including gum fields in Northland. Adults of this species are on the wing from October to December. The life history of this species is unknown as are the host species of its larvae however it has been hypothesised that the likely larval host is a grass or grass like plant. This species is very similar in appearance to I. phaula and I. sapiens but can be distinguished as a result of differences in male antennae, the shape, colour and size of forewings, the range of the species as well as differences in genital shape.

<i>Ichneutica propria</i> Species of moth

Ichneutica propria is a moth of the family Noctuidae. It is endemic to New Zealand. This species is only known from Tongariro National Park and Pureora Forest in the North Island but is widespread in the South Island. I. propria might be confused with faded I. atristriga, however the later species lacks the distinctive marking on the prothorax nor does it have the black mark running through the middle of the forewing. It is very common and widespread in montane to alpine grassland areas. Although the larvae have yet to be described, they have been reared on Poa cita and Festuca novae-zelandiae and are known to feed on introduced grass species. The adults of this species are on the wing from December to mid May and are attracted to light.

<i>Ichneutica unica</i> Species of moth

Ichneutica unica is a species of moth in the family Noctuidae. It is endemic to New Zealand and is found in the centre of the North Island and throughout the South Island. This moth is very similar in appearance to its close relatives Ichneutica phaula and Ichneutica toroneura. I. phaula can be distinguished as there is a difference in pectinations on the male antennae and I. toroneura can be distinguished as the black vein markings on the forewings is more uniform for that species in comparison to I. unica. I. unica is variable in appearance with the North Island specimens having a darker brown colour on the forewings and having a darker underside of the hindwings. This species inhabits open tussock grassland at various altitudes, coastal dunes, and inland volcanic dunes. Larvae feed on tussock grasses such as Chionochloa pallens and species in the genus Poa. Adult moths are on the wing from November to February and are attracted to both sugar and light traps.

<i>Ichneutica averilla</i> Species of moth

Ichneutica averilla is a moth of the family Noctuidae. It is endemic to New Zealand. This species is found in the North Island at Mount Taranaki but is widespread throughout the South Island and Stewart Island. It prefers mountainous habitat but can be found down to sea level in the southern parts of the South Island. Adults of the species are on the wing between November and March. Larvae likely exist on a variety of herbaceous plants but have been recorded as feeding on species within the genus Plantago. This species is sometimes confused with I. mutas but can be distinguished from the latter on the basis of forewing colour as well as the absence of or an indistinct antemedian forewing line.

<i>Ichneutica toroneura</i> Species of moth

Ichneutica toroneura is a moth of the family Noctuidae. It is endemic to New Zealand. This species is similar to I. unica but can be distinguished from that species by the uniform black vein markings on the forewings of I. toroneura. It is also similar in appearance to I. acontistis but the base of the forewings of I. toroneura lack the dark stripe that can be found on the forewings of I. acontistis. The males of I. toroneura have longer pectinations on their antennae. I. toroneura is found in the centre of southern South Island in the tussock grasslands of Central Otago and the Mackenzie Basin. Larvae feed on tussock grasses Poa cita and Festuca novae-zelandiae. Adults are on the wing from November to January.

It prefers alpine to subalpine habitat but occurs down to sea level altitudes in more southern locations. Adults are on the wing from late October to February. Larvae of this species may use tussock grasses in the genus Chionochloa as their host and they have been reared on Festuca novae-zelandiae.

<i>Ichneutica erebia</i> Species of moth

Ichneutica erebia is a moth of the family Noctuidae. This species is endemic to New Zealand and is found on Campbell Island and the Auckland Islands. Adults of this species are on the wing from August to January. The adults are variable in appearance but can be distinguished from similar species by the patters or lack thereof on their forewings. The larvae of I. erebia are polyphagous and hosts include Pleurophyllum criniferum, species within the genera Stilbocarpa and Carex, as well as Chionochloa antarctica, Urtica australis and Raukaua simplex.

<i>Ichneutica brunneosa</i> Species of moth

Ichneutica brunneosa is a moth of the family Noctuidae. This species is endemic to New Zealand. It can be found in the North Island from Mount Te Aroha and in the South Island from the Coromandel to Stewart Island. However it appears to not be present in the centre of the South Island. The distinctive colour and patterns on the forewing of this species ensures it is unlikely to be confused with similar species. It inhabits native forests with higher rainfall and is attracted to mercury vapour light traps. The life history of I. brunneosa is unknown as are the host species of its larvae but the adults of the species are on the wing from October to January.

Ichneutica dundastica is a moth of the family Noctuidae. This species is endemic to New Zealand. As at 2019 this species has only been found near the Dundas Hut in the Tararua Range near Wellington. It inhabits alpine shrubland and is attracted to light. The life history of this species is unknown as are the host species of its larvae however adults are on the wing from late November to early December. The female of the species is larger and more conspicuous than the male.

Ichneutica peridotea is a moth of the family Noctuidae. This species is endemic to New Zealand. The species is similar in appearance to Ichneutica plena but are more dull olive-green in appearance and the male lacks the patches of orange-brown forewing scales of the male I. plena. As at 2021 I. peridotera has only been collected in the Auckland District although Robert Hoare hypothesises that its range may include the northern districts of the North Island. The lack of information about this species is partially due to the fact it is late winter flying. The life history of this species is unknown as are the hosts of its larvae. Its preferred habitat is forest and the adults are attracted to light.

Ichneutica cornuta is a moth of the family Noctuidae. This species is endemic to New Zealand and is only found in the South Island, in and around the Southern Alps. I. cornuta is very similar in appearance to pale forms of I. arotis. It is easy to confuse the two species as their ranges overlap. Male I. cornuta can be distinguished as it has longer pectinations on the antennae and the female lacks the dark scaling that can be found on the thorax of the I. arotis. There are also subtle differences in the forewing patterns of the two species. The life history of this species is unknown as are the host species of its larvae. Adults are on the wing from January to April.
