Taxonomy

This species was first described in 1887 by Edward Meyrick using a male specimen collected at Mount Arthur under the name I. ceraunias. [1] This species name has been misspelt as Ichneutica caraunias.

I. ceraunias was discussed and illustrated by George Hudson in his books published in 1898 and 1928. [2] [3] John S. Dugdale agreed with the placement of this species within the Ichneutica genus in 1988. [4] Robert J. B. Hoare also confirmed the placement of this species within the Ichneutica genus in his major review of New Zealand Noctuidae species in 2019. [5]

Meyrick originally described this species as follows:

41 mm. Head, palpi, antennae, thorax, abdomen, and legs brownish-ochreous ; palpi externally suffused with dark fuscous ; stalk of antennae white above. Forewings moderately dilated, costa almost straight, apex obtuse, hindmargin rather oblique, rounded beneath ; whitish-ochreous, brownish-tinged ; a pale yellow-ochreous gradually dilated streak from base above middle to 35, where it separates abruptly into two strong remote branches, nearly reaching hindmargin, upper acutely pointed, lower with two acute points ; space between and beyond these, and on a broad streak beneath them, reaching from 13 to hindmargin but acutely attenuated anteriorly, ochreous-brown, sprinkled with black on margins ; a small blackish spot between branches at origin, and an irregular black divided streak from base beneath median streaks to middle : cilia whitish-ochreous (imperfect). Hindwings light fuscous-grey ; cilia whitish-ochreous (imperfect). [1]

This species is variable in the intensity of its colour and markings with darker specimens being found in the South. [3] The pale streaks on the forewing help identify this species but some forms of I. dione can be confused with I. ceraunias. [5] Some populations have full winged females, others have brachypterous, flightless females with the form of the wing reduction being variable. [5]

The larvae of the species has been partially described but there is no full description of the larvae of this species. [5]

Geographic range

I. ceraunias is found from central North Island down and throughout the South Island. [5]

Habitat

The species inhabits the alpine zone in the northern sections of its range down to sea-level in the south. [5]

Host species

The larvae of I. ceraunias feed on Chionochloa and Festuca species. [5]

Behaviour

Although adult moths are known to fly during the day it is more common to see them at night. [5] They are attracted to light. [3] Adults are on the wing from October to February. [5]

Conservation

Currently this species is not listed as in need of conservation efforts. [6]

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

Isonomeutis amauropa is a species of moth in the Copromorphidae family. It is endemic to New Zealand where it can be found on both the North and South Islands. I. amauropa inhabits native forest particularly forest dominated by Rimu and native beech trees. The larvae of this species consumes margarodid scale insects that live under the bark of these trees. When mature the larvae pupate in a cocoon made of silk and covered in twigs and frass. This cocoon is normally placed under the bark of the same tree the larvae inhabited. Adults of I. amauropa are on the wing from September to February.

<i>Physetica prionistis</i> Species of moth endemic to New Zealand

Physetica prionistis is a moth of the family Noctuidae. It was described by Edward Meyrick in 1887. It is endemic to New Zealand and is widespread throughout the North, South and Chatham Islands. This species can be found in open clearings of shrubland and forest at altitudes from sea level up to the alpine zone. Adults are on the wing throughout the year and are attracted to sugar traps and occasionally to light. The life history of this species is unknown as are the larval host species.

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

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.

<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 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 steropastis</i> Species of moth endemic to New Zealand

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.

<i>Pyrgotis plinthoglypta</i> Species of moth endemic to New Zealand

Pyrgotis plinthoglypta is a species of moth of the family Tortricidae. It is endemic to New Zealand and is found throughout the whole country. The preferred habitat of this species is native forest. The larvae of this species feeds on rimu leaves from under a silken web. It pupates in loose cocoons amongst rimu foliage. Adults are on the wing from October to May and are night flying. They are attracted to light and can be collected by beating their host tree. The adult insect resembles a small dried fragment of rimu foliage when at rest.

<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.

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

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.

<i>Ichneutica dione</i> Species of moth endemic to New Zealand

Ichneutica dione is a moth of the family Noctuidae. It is endemic to New Zealand. This moth species is closely related to I. ceraunias and is very similar in appearance to that species. However I. dione has a much more restrictive range, being found only in the alpine zone and hills of the South Island and is less commonly collected. Adults of the species are on the wing from December to February and although sometimes can be found flying during the day, they are more commonly seen at night.

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

Ichneutica cana is a moth of the family Noctuidae. It is endemic to New Zealand.

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

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.

<i>Physetica homoscia</i> Species of moth endemic to New Zealand

Physetica homoscia is a species of moth of the family Noctuidae. It is endemic to New Zealand and is found throughout New Zealand including in the Auckland Islands. This species inhabits places where its host plants are common and this includes costal dune habitat. It lives at a wide range of altitudes from sea-level up to at least 1750 m. The larvae of P. homoscia feed on Ozothamnus leptophyllus and Ozothamnus vauvilliersii. They are very active and drop to the ground when disturbed. Larvae are parasitised by a species of fly. This species pupates in the soil and the pupa life stage lasts for approximately 6 weeks. The adult moths are on the wing from September to June and are attracted to light. The adults of P. homoscia might possibly be confused with Ichneutica moderata however this latter species lacks the small white dots on the forewing veins of P. homoscia. Adults might also be confused with P. temperata but P. homoscia is significantly larger in size.
