Ichneutica eris is a moth of the family Noctuidae. [1] It is endemic to New Zealand. It is found in alpine habitat in the South Island and is on the wing from November to February. The species is attracted to light.

Contents

Taxonomy

This species was first described by Robert Hoare in 2019. [2] The holotype specimen was collected near the Homer Tunnel by John Salmon in 1946. [1] I. eris was named in honour of Eris in light of the difficulty of the confusion this species has caused lepidopterists. [1]

Description

Adults of this species are brownish-grey in colour, with whitish markings on the forewings as well as greyish dots along the forewing edge. [1] The hindwings are grey in colour. [1] The wingspan range for the male of the species is between 37 and 46 mm, and for the female is between 43 and 51 mm. [1]

This species is similar in appearance to both I. cana and I. fibriata. [1]

Habitat and geographic range

This species is endemic to New Zealand and can be found throughout the South Island in alpine habitat. [1] This species overlaps with the range of I. cana although it appears to be more restricted in range than that species. [1] However, I. eris can be found in the mountains surrounding Nelson, whereas I. cana is not present in that locality. [1]

Life history

Little is known of the life history of this species. [1] However, it is possible that the larvae exist on short alpine grasses and pupate on bare soil. [1]

Behaviour

Adults of this species are on the wing from November to February. [1] This species also appears to be attracted to light. [3]

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

Ichneutica ustistriga is a moth of the family Noctuidae. It is endemic to New Zealand and can be found from the Three Kings Islands to Stewart Island. This species lives in a wide variety of habitats including domestic gardens, horticultural areas, orchards, native and exotic grasslands, as well as native forest. The larvae eat a variety of herbaceous plants. Recorded food plants include Muehlenbeckia australis, Muehlenbeckia complexa, Olearia hectorii, Plantago lanceolata, and Urtica australis. This moth has a mauvish grey wing colour and is unlikely to be confused with other species as the patterns on its forewing are distinctive. This species is on the wing throughout the year and is attracted to both sugar and light traps. Adult moths can be found at rest on fences and tree trunks during the day.

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

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.

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

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.

<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 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 alopa</i> Species of moth

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.

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

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.

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

Ichneutica fibriata is a moth in the family Noctuidae. It is endemic to New Zealand. Specimens of this moth were first collected by Frederick Giles Gibbs. The species is similar in appearance to other species in the Ichneutica genus particularly I. eris but can be distinguished due to its larger size and more uniform light grey colour. I. fibriata also has a similar coloured thorax and head where as these two anatomical features may differ in colour shade in I. eris. Adults frequent alpine areas and are on the wing in November to January. The life history and the host species of the larvae of this species is unknown.

<i>Ichneutica notata</i> Species of moth 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.

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

Ichneutica nobilia is a moth of the family Noctuidae. This species is endemic to New Zealand and can be found in the South Island, although not in the Nelson, Dunedin or Southland regions. This species prefers rocky habitats in alpine zones and the blueish-grey sheen on the species' forewings help camouflage it. Adults of I. nobilia are on the wing from December to February and are attracted to light. The life history of this species is unknown as are the host species of its larvae.

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

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 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.
