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 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. It inhabits tussock and shrubland in the alpine to subalpine zones. Adults of I. petrograpta are on the wing from December to February and are attracted to sugar traps. The life history of this species is unknown as are the host species of its larvae.
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 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.
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 alopa is a moth of the family Noctuidae. It is endemic to New Zealand and is found in the central and southern parts of the North Island as well as in the South Island. It inhabits tussock grasslands and wetlands and can occur at ranges from the alpine zone down to almost sea-level. The life history of this species is unknown as are the host species of its larvae in the wild. Larvae of this species have been raised in captivity on Sphagnum moss as well as on species in the genus Raoulia. Adults of this species are on the wing from late January to April and are attracted to light and to sugar traps. I. alope can be confused with I. agorastis, I. micrastra or I. sapiens but the latter three species can be distinguished externally from I. alope through differences in size, forewing pattern and the antennae of the male of the species.
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 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.
Ichneutica phaula is a moth of the family Noctuidae. It is endemic to New Zealand. It is found only in the South Island in the Nelson district, the eastern side of the South Island and Stewart Island. I. phaula inhabits tussock grasslands and coastal sand dunes. Host species include Ficinia spiralis, Ammophila arenaria, Poa cita and other "tussock grasses". The adults of this species are on the wing from October to December and are attracted to sugar traps. I. phaula is similar in appearance to both I. micastra, with whom it does not share a range, and I. sapiens which differs from I. phaula as I. sapiens is darker and has a more reddish tinge.
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.
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 steropastis, or the flax notcher moth, is a species of moth in the family Noctuidae. It is endemic to New Zealand and can be found throughout the country from the Three Kings Islands to Stewart Island as well as in the Chatham Islands. The larvae of this species feed on a variety of native and introduced plants however the New Zealand flax is one of the more well known host plants for the larvae of this moth. The larvae are nocturnal, hiding away in the base of the plants and coming out to feed at night. They create a distinctive notch in the leaf when they feed. The adults of this species are on the wing from October to March. Although adult specimens of I. steropastis are relatively easy to recognise they might possibly be confused with I. inscripta, I. theobroma or with darker forms of I. arotis. However I. steropastis can be distinguished as it has a long dark basal forewing streak that these three species lack.
Ichneutica similis is a moth of the family Noctuidae. It is endemic to New Zealand. This species is found only in certain parts of the North Island, in the western side of the South Island and on Stewart Island. It inhabits peatlands as well as inland and coastal wetlands. The life history of this species is unknown and the host species of its larvae has yet to be confirmed. It has been hypothesised that larval host species might be within the Empodisma genus as well as possibly the species Apodasmia similis.
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.
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 epiastra is a moth of the family Noctuidae. It is endemic to New Zealand and is found throughout the North, South and Stewart Islands. This species prefers open habitats such as wetlands, dunes and forest clearings. Eggs are laid in the summer or autumn and larvae feed during winter and spring. The larval host species are found within the genus Austroderia. The adult moths are on the wing between October and February. Adult I. epiastra can possibly be confused with the similar species I. arotis and I. haedifrontella however there are differences in appearance that enables I. epiastra to be distinguished from these two species. In particular I. epiastra has long sharp-tipped ‘horns' on its head that are diagnostic. The adults of this species appear reluctant to be attracted to light although they do come more frequently to the brighter mercury vapour traps.
Ichneutica agorastis is a moth of the family Noctuidae. This species is endemic to New Zealand. This moth is similar in appearance to two other species in the genus but can be distinguished through the colour and size of its forewings. This species is found in the South Island and Stewart Island in open habitats in the subalpine zone. However, in Southland I. agorastis can be found down to sea-level. Adult moths are on the wing between January and April. The life history and host species are unknown.
Ichneutica fenwicki is a moth of the family Noctuidae. This species is endemic to New Zealand and is found in the southern parts of the South Island and on Stewart Island. It is a distinctively coloured moth that is unlikely to be confused with closely related species. It is a spring flying moth being on the wing from September to November. The life history and host species of the larvae of I. fenwicki are unknown.
Ichneutica sollennis is a moth of the family Noctuidae. This species is endemic to New Zealand. This species is known from the eastern and central areas of the southern South Island. It inhabits alpine zones and has been collected in tussock grasslands. The life history of this species is unknown. Although the host species is currently unknown it has been hypothesised that this species have grass or grass like plants as host plants. Adults are on the wing from November to February and are attracted to light.
Ichneutica paracausta is a moth of the family Noctuidae. This species is endemic to New Zealand. It is found locally in the central North Island, is widespread in the South Island and can also be found in Stewart Island. I. paracausta is variable in colour, but as it has a distinctive black streak on its forewing as well as a wing pattern that is characteristic, I. paracausta is unlikely to be confused with other species. It is present on the North Island volcanic plateau as well as Little Bush Reserve in Hawkes Bay in the North Island as well as in tussock grassland, alpine and subalpine shrubland and in alpine forest. Larvae have been recorded as feeding on grasses, a pupa has been found in a cocoon under the bark of a tree and adult moths are on the wing from October to January.
