Proteuxoa comma is a species of moth in the family Noctuidae. It is endemic to New Zealand. It can be found in the lower half of the North Island and throughout the South Island, although it appears to be more frequent on the eastern side of these islands, and also is present in Stewart Island. P. comma is very similar in appearance to P. tetronycha but can be distinguished as it is a larger moth with slightly different colouration on, as well as shape of, its forewings. This species pupates in the soil. The adult moths are on the wing from December to April. P. comma may possibly be declining in population and as at 2017 a reassessment of its conservation status is regarded as being needed.

Taxonomy

This species was originally described by Francis Walker in 1856 and named Mamestra comma. [3] [2] The female holotype specimen was collected by Reverend John Frederick Churton. [2] J. S. Dugdale presumed Churton collected this specimen in Auckland however Robert Hoare has hypothesised that Wellington may possibly be the type locality for this species. [4] [2] The holotype specimen is held at the Natural History Museum, London. [2] In 1857 Walker, thinking he was describing a new species, again named this species Graphiphora implexa. [5] In 1868 Achille Guenée replaced Walker's comma name with Nitocris bicomma. [6] In 1887 Edward Meyrick synonymised both this name and Graphiphora implexa and moved the species into the Orthosia genus. [7] In 1988 J. S. Dugdale placed this species in the Rictonis genus. [4] In 2017 Robert Hoare undertook a review of Noctuinae. In this review he placed this species in the Proteuxoa genus. [2]

Description

Walker originally described the species as follows:

Female. Cinereous. Head whitish. Palpi with whitish tips. Thorax and fore wings sprinkled with brown. Fore wings with brown transverse undulating or zigzag lines. Hind wings paler towards the base. Length of the body 6 lines ; of the wings 16 lines. [3]

The adult male of this species has a wingspan of between 32 and 37 mm and the female has a wingspan of between 33 and 37 mm. P. comma can be distinguished from the very similar P. tetronycha as P. comma has a less contrasting prothoracic collar and a more grey forewing ground colour. [2] P. comma also has a narrower winged appearance than P. tetronycha. [2] P. comma is slightly larger than P. tetronycha. [2] If the wingspan of a specimen is above 33 mm then the species is P. comma. [2]

Distribution

This species is endemic to New Zealand. [1] The species can be found in the lower half of the North Island and throughout the South Island, although it appears to be more frequent on the drier, eastern side of these islands, and is also present in Stewart Island. [2]

Behaviour

This species pupates in the soil. [2] The adults of this species are on the wing from December to April. [2]

Biology and host species

As a result of the previous confusion with P. tetronycha, as at 2017 there is currently no description of P. comma larva that does not also relate to P. tetronycha. [2] The same is true for larval host species and rearing records, although P. comma larvae have been reared on Brassica oleracea . [2]

Conservation status

P. comma may possibly be declining in population, likely caused by environmental changes. [2] Hoare advocates for a reassessment of this species conservation status. [2]

Physetica caerulea is a species of moth of the family Noctuidae. It is endemic to New Zealand and can be found from the centre of the North Island south, including the South and Stewart Islands. The adult moths are variable in appearance but can be distinguished by the bluish tinge to the forewings as well as the underside buff colour. However this species does have several forms including a very dark bluish black form, a brownish form and a green-brown form. It lives in open habitats and can be found in tussock grasslands and dunes and can normally be found from altitudes of sea level up to 900 m. Adults of this species are on the wing from August to April. As at 2017, the life history of is unknown as are the host species of its larvae. However it has been hypothesised that the larval host species is a tomentose plant.

<i>Austramathes purpurea</i> Species of moth endemic to New Zealand

Austramathes purpurea is a species of moth in the family Noctuidae. It is endemic to New Zealand and can be found throughout the North and South Islands but has yet to be recorded at Stewart Island. It inhabits native forest. This species might possibly be confused with A. pessota, however this latter species does not have the purple hue to the forewings. The larvae of A. purpurea feed primarily on māhoe but have been recorded as feeding on, and have been reared on, narrow-leaved māhoe. The larvae pupate in a silken cocoon on moss covered ground. Adults can be found on the wing during the months of March to January but mainly occur during New Zealand's late autumn, winter, and spring. Light trapping may not be the most efficient technique for collecting this species.

<i>Austramathes fortis</i> Species of moth

Austramathes fortis is a species of moth in the family Noctuidae. It is endemic to New Zealand and is found in both the North and the South Islands but has yet to be recorded at Stewart Island. It can be found in shrubland containing its host species at a range of altitudes from sea-level up to 1840 m. The larvae of this moth feed on several Melicytus species including M. crassifolius, M. alpinus, M. macrophyllus and M. novae-zelandiae. The larvae pupate in a cocoon of silk at the base of its host plant. It can take between 25 and 45 days before the adult moth emerges. Adults can be found on the wing during the months of July to March. The adults tend to be on the wing in twilight hours but have also been known to be active during the late afternoon. They are attracted to light but this behaviour may limit the number seen at light traps. The distinguishing feature of this moth is the curved black line at the base of its forewing. This species is unlikely to be confused with any other species in its range but it is very similar in appearance to A. squaliolus. However this latter species is only found on the Chatham Islands.

<i>Austramathes pessota</i> Species of moth endemic to New Zealand

Austramathes pessota is a species of moth in the family Noctuidae. It is endemic to New Zealand and is found in Northland, in the southern North Island and in the South Island, mainly on the eastern side of that island but is also present in Fiordland. It is not regarded as being present in either Dunedin or the Southland district. This species lives in shrubland at altitudes ranging from sea-level up to subalpine. As at 2017, the larvae have yet to be described or photographed but it is known that they feed on Melicytus alpinus and it is likely that Melicytus micranthus is also a host. Adults of this species are distinctively patterned and coloured. Its appearance differs from its close relatives such as A. purpurea as it lacks the purple hue that can be seen on the latter species forewings. It also differs from A. coelacantha as it is much darker and has a distinctive small, round, pale mark on its forewing. Adults are on the wing from December to April.

<i>Proteuxoa tetronycha</i> Species of moth

Proteuxoa tetronycha is a moth of the family Noctuidae. It is endemic, and can be found throughout, New Zealand. This species was previously muddled up with the rarer Proteuxoa comma and is very similar in appearance to that other species. P. tetronycha can be distinguished from P. comma by the paler colour of its prothorax as well as the browner base colour of its forewings. P. tetronycha is also a smaller moth with the wingspan of the adults of this species being between 29 and 33 mm. There are also differences between the females of these two species. For the females of P. tetronycha, their ovipositor is lacking the spiny hair like structures that are present on the ovipositor of P. comma. Larvae likely feed on a variety of host species and have been raised on Acaena species as well as Poa cita. The adults of this species are on the wing from September to March and are attracted to light.

<i>Nivetica nervosa</i> Species of moth endemic to New Zealand

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.

<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>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.

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

Physetica temperata is a species of moth of the family Noctuidae. It is endemic to New Zealand and found in the North Island and the top of the South Island in coastal areas. P. temperata is unlikely to be confused with other species in its range, even though it is not distinctively patterned. It is possible that males might be confused with males of P. homoscia but this latter species is much larger. P. temperata can be distinguished from P. caerulea as the former species has forewing veins that are marked black and a chequered forewing fringe. The adults of this species are on the wing from September to March. The life history of this species has not been well documented although it is thought that larval host species is Ozothamnus leptophyllus.

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

Physetica cucullina is a species of moth of the family Noctuidae. It is endemic to New Zealand and can be found throughout the South Island, apart from in the Nelson district with the exception of the St Arnaud Range where it is present. It is likely to be also resident in Stewart Island. P. cucullina lives in shrubland at subalpine and alpine zones but can occur at sea-level in the more southern regions. The life history of this species is poorly documented. There is only one known record in the New Zealand Arthropod Collection of the larvae of this species having been reared. These larvae were reared on Leucopogon fraseri. Adults of this species is on the wing from October to March and are attracted to light. P. cucullina is almost identical in appearance to P. funerea. The only reliable distinguishing feature between the two species is the antennae of the male. P. cucullina is also very similar in appearance to P. sequens but P. sequens lacks the narrow black line on the forewing dorsum area that can be present on the forewings of P. cucullina.

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

Physetica sequens is a species of moth of the family Noctuidae. It is endemic to New Zealand and can be found throughout the North and South Islands. It appears to be more common in the North Island than the South Island, and lives in open native shrublands, peatlands, Northland gumland, inland volcanic dunes, and Dracophyllum-dominated areas at altitudes that range from sea level to the alpine zone, up to at least 1600 m. Larvae of this species have been successfully reared on Leucopogon fasciculatus and Leptecophylla juniperina. The adults of this species are variable in appearance and are on the wing from September to March. P. sequens is similar in appearance to P. phricias but can be distinguished as P. phricias has a narrow black line along the dorsum of its forewing that P. sequens does not. P. sequens is also similar in appearance to P. cucullina however the forewing dorsum area of P. sequens does not have the narrow black line that is frequently present on P. cucullina forewings.
