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 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.
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 omoplaca is a moth of the family Noctuidae. It is endemic to New Zealand. It is widespread from the Bay of Plenty in the North Island down to Southland in the South Island. Specimens have also been collected from the Auckland Islands. It lives in a variety of habitats including beech forest clearings and tussock grasslands. This species has been recorded that some of the larval hosts of this species include Poa cita, Dactylis glomerata and it has been reared on Plantago lanceolata. The larva is undescribed but pupae have been found in a pine plantation in soil under weeds. Adults of this species are on the wing from October to March. The adult moths are variable in appearance but the diagnostic feature is the pale ochreous to white colouring between the basal streak and the costa which contrasts with the ground colour of the forewing.
Ichneutica rubescens is a moth of the family Noctuidae. It is endemic to New Zealand. This species can be found locally in the North Island but is widespread throughout the South Island and is present on both Stewart Island and the Auckland Islands. I. rubescens has a round or oval mark near the centre of the forewing that encloses a dot. This is diagnostic of this species. I. rubescens inhabits tussock grasslands, beech as well as podocarp forests. Larval hosts are likely herbaceous plants such as grasses and herbs and larvae have been reared on Gunnera prorepens. Adults of this species are on the wing from December to April and are attracted to light.
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 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 disjungens is a moth of the family Noctuidae. This species is endemic to New Zealand and can be found on the central volcanic plateau of the North Island and in the eastern as well as the south western parts of the South Island. I. disjungens inhabits tussock grasslands in the alpine and subalpine zones. The hosts of the larvae of this species include Poa cita, P. colensoi, and Festuca novae-zelandiae. The adults of this species are distinctive and are unlikely to be confused with other species. They are on the wing between October and March.
Ichneutica bromias is a moth of the family Noctuidae. This species is endemic to the Chatham Islands of New Zealand where is found on the Chatham, Pitt and Rangatira Islands. This species is similar in appearance to Ichneutica mutans but is darker and duller in its overall appearance. However, as I. mutans is not present in the Chathams this similarity is unlikely to cause confusion. The adults of the species are on the wing from November to March. The life history and the larval host species are unknown.
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 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 sapiens is a moth of the family Noctuidae. This species is endemic to New Zealand. I. sapiens is found in the central North Island, in the South Island in Westland and also the southern parts of the South Island, and in Stewart Island. This species inhabits wetland habitat but its life history is unknown as are the host species of its larvae. The adult moths are on the wing between December and early January and are attracted to sugar traps and to light. I. sapiens is very similar in appearance to I. micrastra but is a smaller moth with a shorter wingspan, has differently formed antennae and slightly different forewing markings.
Ichneutica emmersonorum is a moth of the family Noctuidae. This species is endemic to New Zealand. It is very similar to I. similis but its forewings have visual differences. I. emmersonorum is only known from the North Island volcanic plateau. The life history of this species is unknown as are the host species of its larvae however Robert Hoare argues that the likely larval host plant species is a grass or grass like plant. The adult moths are on the wing from November to January. This species is attracted to sugar traps and to light.
Ichneutica theobroma is a moth of the family Noctuidae. This species is endemic to New Zealand. The males of this species has a pink chocolate brown appearance to its forewings with a small white dot. The males of this species can be distinguished from the 'northern dark form' of Ichneutica arotis as they have broader shaped forewings with less markings than the latter species. The females are extremely difficult if not impossible to tell apart. I. theobroma are found in the northern parts of the North Island and inhabit kauri forests. The life history of this species is unknown as are the host species of its larvae although it has been hypothesised that larval hosts include Gahnia setifolia and Gahnia xanthocarpa. Adults of this species are on the wing from mid September until early November and are attracted to light.

Ichneutica mustulenta is a moth of the family Noctuidae. This species is endemic to New Zealand is widespread throughout the North, South and Stewart Islands. I. mustulenta prefers damp native forest in the west of the North and South Islands. Its range only overlaps with its close relative I. morosa in a few places such as Taranaki. The life history of this species is unknown as are the host species of its larvae. However it is assumed that the larval hosts of this species will be grasses similar to its close relatives in the same genus. Adults of this species are on the wing from January to March.
Ichneutica supersulcana is a moth of the family Noctuidae. This species is endemic to New Zealand and is only known from the Tararua Ranges and at Tongariro National Park. This species has been collected in subalpine tussock grasslands as well as subalpine shrubland and at the margins of Fuscospora cliffortioides forest. The life history of this species is unknown as are the host species of its larvae. The adults of this species are on the wing in February and are attracted to light. It appears to be restricted to higher altitudes in comparison to its close relative I. sulcana.I. sulcana and I. supersulcana are very similar in appearance with no reliable visible differences between the two having been discovered.
