Ichneutica semivittata is a moth of the family Noctuidae. It is endemic to New Zealand. It can be found from the Three King Islands down to Stewart Island. The similar species I. sulcana can be distinguished from I. semivittata as the former is much larger, has a darker hindwing and abdomen and has only one to three spots located behind the middle of the forewing in comparison to the 8 or 9 of I. semivittata. This species lives in a variety of habitats from open grasslands to clearings in forest and at a range of altitudes from the sea level to the alpine zone. Larval host species include Juncus procera, Carex secta as well as on tussock grasses such as Poa cita, P. colensoi and Festuca novae-zelandiae. Adults of this species are on the wing from August to April and are attracted to light.
Ichneutica lissoxyla is a moth of the family Noctuidae. It is endemic to New Zealand. It is found in the central and southern parts of the North Island and in most parts of the South Island. The species prefers snowgrass habitat in the alpine zone. I. lissoxyla is similar in appearance to I. paraxysta but can be distinguished as I. lissoxyla lack the black streaks on the forewings that can be found on the latter species and the male I. lissoxyla also has longer pectinations on antennae. 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 and are attracted to the light.
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.
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.
Ichneutica scutata is a moth of the family Noctuidae. It is endemic to New Zealand. This species can be found in the southern parts of the North Island as well as the eastern parts of the South Island. It is similar in appearance to I. insignis and I. skelloni but can be distinguished as I. scutata is much paler in appearance. It is likely this species inhabits lowland tussock grasslands as well as coastal dunes although it is not common in inland tussock grasslands. The larvae feed on a variety of herbaceous plants such as Plantago and Convolvulus species, Plagianthus divaricatus. It pupates on soil near its host plants. The adults are on the wing from late March to July.
Ichneutica arotis is a moth of the family Noctuidae. It is endemic to New Zealand. This species is found throughout the North and South Islands but has yet to be recorded on Stewart Island. I. arotis is variable in appearance and have been described as having a "northern dark form", a "typical" form and a "swamp" form. Robert Hoare hypothesised that this species may be in the process of evolving into several distinct species. However, as these forms show no difference in antennae or genitalia so, as at 2019, they are not regarded as separate species. Larval hosts include species in the genera Cortaderia and Schoenus as well as Phormium tenax. The caterpillar feeds at night and rests in during the day amongst dead flax leaves. It pupates in a loose cocoon either hidden at the base of a stem of flax or on the ground. The adults of this species is on the wing from September to April. In the North Island there have also been records of adults being on the wing in June to August.
Ichneutica blenheimensis is a species of moth in the family Noctuidae. It is endemic to New Zealand and is found throughout the North, South and the Stewart Islands. This species appears to prefer drier eastern localities and is rarely collected in western North Island forested areas. It does not appear to be frequently collected in inland dry tussock grassland habitats. The host plant for the larvae of this species is likely to be the golden sand sedge pīngao which is now absent from the moths type locality. However Chappell has raised very young larvae on grass species and the more developed larvae consumed Phormium tenax. Adults are on the wing from November to March and are attracted to both light and sugar traps. The blackish forewing fringes are diagnostic of this species. But worn specimens of I. arotis can be confused with worn specimens of I. blenheimensis. However I. arotis can be distinguished from I. blenheimensis as it has a scale-tuft on the thorax and dark longitudinal stripes on the tegula. This species is classified as "At Risk, Naturally Uncommon" by the Department of Conservation.
Ichneutica sulcana, the dark underwing wainscot, is a moth of the family Noctuidae. It is endemic to New Zealand and can be found throughout the North, South and Stewart Islands at a range of altitudes from the lowlands to the alpine zone. This species prefers to live in native grass, shrub and wetland habitats as well as in native forest. The larval host plants of this species are forest grasses and sedges and larvae have been reared on Microlaena avenacea and species within the genus Carex. The larva pupates in the soil. Adults are on the wing from December to May but have also been recorded in August and September in the northern parts of the North Island. They are attracted to sugar traps as well as to light. I. sulcana and I. supersulcana are very similar in appearance but can be distinguished as there are differences in the male abdomen and genitalia of the two species. Also these two species do not appear to share a range as I. supersulcana seems to prefer to live at higher altitudes than I. sulcana. I. sulcana might also be confused with I. semivittata but I. sulcana is a larger species with a much darker abdomen and hindwing, and has only 1 to 3 dots on the forewing postmedian line.
Ichneutica stulta is a moth of the family Noctuidae. It is endemic to New Zealand. This species has only been collected from West Plains and Tuturau in Southland but, as at 2021, no male species appears to exist in collections. I. stulta can resemble I. acontistis but can be distinguished as I. stulta has a strongly curved forewing edge as well as having a discal spot on the underside of the hindwing. I. stulta is also darker than specimens of I. acontistis obtained in the southern parts of the South Island. I. stulta is also very similar in appearance to I. emmersonorum but the later species has darker forewings and is more strongly marked on the thorax. The life history of this species is unknown as are the host species of the larvae but the adults have been recorded as being on the wing from October to December.
Ichneutica purdii, the orange astelia wainscot, is a moth of the family Noctuidae. It is endemic to New Zealand. It can be found throughout the main islands of New Zealand. I. purdii is a relatively large, colourful moth, unlikely to be confused with any other endemic moth species in New Zealand. The larvae of this moth feed at night on species of Astelia. During the day they shelter in the interior of the plant. When fully grown the larvae can reach a length of approximately 48mm. The larvae are ocherous in colour with a pink flush with line markings but when ready to pupate these markings fade and the larvae take on a light golden hue with a rosy tinge to its rear segments. The deep wine coloured pupa is enclosed in a slight cocoon, with this being constructed below the soil, amongst debris or alternatively within a hollow stick. The adult moths are on the wing from October to March. Although this moth is found throughout the main islands of New Zealand it is more frequent in the south of New Zealand at higher altitudes of up to 1200m.
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.
Ichneutica paraxysta is a moth of the family Noctuidae. It is endemic to New Zealand. This species is very similar in appearance to its close relative I. acontistis but as the range of the two species do not overlap this is unlikely to cause confusion. I. paraxysta is only found in the North Island at the subalpine zones in the Mount Taranaki region and at Mount Ruapehu. It prefers tussock grassland and shrubland habitat. The life history of this species is unknown as are the host species of its larvae however it has been hypothesised that the larval host plants are species in the genera of Poa and Festuca.
Ichneutica panda is a species of moth in the family Noctuidae. It is endemic to New Zealand and only found in central and southern parts of the South Island. The species has not been collected in Canterbury since the late 1950s and has not been seen at The Wilderness scientific reserve since 1941. This species is similar in appearance to Ichneutica falsidica however I. panda lack or have indistinct black dashes on their edge of their hindwings. I. panda inhabit shrubland from alpine zones down to river terraces and adults are on the wing between December and February. The life history of this species is unknown as is the host species of the larvae.
Nivetica nervosa is a moth of the family Noctuidae. It is only found in New Zealand. This species can be found in wetland habitat in the alpine zone of the South Island. It is a small, distinctively patterned moth that is attracted to light. Currently much of its biology and life cycle is unknown. Adults are on the wing in January and February.
Ichneutica ceraunias is a moth of the family Noctuidae. It is endemic to New Zealand. This species is found from the central North Island to the bottom of the South Island. Hosts of the larvae are species of Chionochloa and Festuca. This colourful moth is variable in appearance and can be mistaken for Ichneutica dione. Adults are on the wing from October to February.
Ichneutica cana is a moth of the family Noctuidae. It is endemic to New Zealand.
Ichneutica notata is a moth of the family Noctuidae. It is endemic to New Zealand. Although similar in appearance to other species in the Ichneutica genus, it can be distinguished by the colouration and patterns on its wings. It appears to be a very local species, rarely collected and having only been recorded in the north-west of the Tasman District, the Paproa Range, the Rainbow Ski field and the Craigieburn Range. Very little is known of the life history of I. notata.
Ichneutica marmorata is a moth of the family Noctuidae. This species is endemic to New Zealand and can be found in the North Island at the Tongariro National Park and at Puketitiri near the Kaweka Range. In the South Island it is widespread. 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.
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.
Ichneutica lindsayorum is a moth of the family Noctuidae. This species is endemic to New Zealand and can be found in the southern parts of the North Island and in the South Island. I. lindsayorum is very similar in appearance to I. olivea but has a longer basal streak and lacks the white scaling from the subterminal line on the forewing that can be found on the forewings of I. olivea. The life history of this species is unknown as are the host species of its larvae in the wild. However larvae have been reared on Ozothamnus leptophyllus. The adults of this species are on the wing from December to April.
