Sestra flexata, also known as the common fern looper, is a species of moth in the family Geometridae. [3] This species is endemic to New Zealand.
S. flexata was first described by Francis Walker in 1862 using specimens collected either in Auckland by D. Bolton. [4] Walker originally named the species Cidaria flexata. [2] George Hudson discussed and illustrated this species in his 1928 book The butterflies and moths of New Zealand. [5] The male holotype is held at the Natural History Museum, London. [2]
The pale yellow egg is cylindrical in shape. [6] The larva of this species is coloured dark brown and is 25 to 30 mm long when mature. [7] The larvae are approximately 1 to 1+1⁄4 inch long and is a brownish greenish colour with yellow tones underneath. Down its back is a brown line with two more lines down its sides. It also has a few black markings and a number of short bristles. [6]
Walker described the adult of this species as follows:
Female. Cinereous fawn-colour, ochraceous beneath. Palpi slender, very short, obliquely ascending. Abdomen yellowish. Forewings acute, subfalcate, with a blackish shade on nearly half the middle space and along the exterior border, which is distinctly angular. Hind wings yellowish, without markings; fore part of the exterior border slightly truncated. Length of the body 6 lines; of the wings 16 lines. [4]
Hudson described the adults of this species as follows:
The expansion of the wings is from 1+1⁄4 to 1+3⁄8 inches. The fore-wings are pale plum-colour; there is an indistinct, curved, brownish transverse line near the base; a straight dark brown line across the middle, and a curved series of brownish dots beyond the middle; the apex is pointed, and the termen has a strong projection a little above the middle. The hind-wings are ochreous, with a series of minute brownish dots across the middle. [5]
This species is endemic to New Zealand. [1] This species is found throughout New Zealand including the North, South, Stewart and Chatham Islands. [6]
The larval hosts of this species are Pteris macilenta and Histiopteris incisa . [7] It has been collected by beating the latter fern. [6]
The older larvae of this species feed at night. [7] When disturbed the larva will drop to the ground. [7] Adults of this species pollinate Leptospermum scoparium . [8] The adult moths are nocturnal, are attracted to light and on the wing from September until March. [7] [6]
Ichneutica insignis is a moth of the family Noctuidae. It is endemic to and found throughout New Zealand, although it appears to be scarce at inland sites of tussock grasslands. The adults are on the wing throughout the year. It is a variable species and as such can be easily confused with I. skelloni and I. plena. The larvae of this species have been recorded as feeding on Trifolium pratense.
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, and Plantago lanceolata. 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.
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.
Phaeosaces coarctatella is a species of moth in the family Oecophoridae. It is endemic to New Zealand and can be found throughout the country. The preferred habitat of this species is native forest however they can also be found in domestic gardens. Larvae shelter in hollow twigs or under bark and emerge at night to browse on lichens. They pupate within their shelter. Adults are on the wing from September to January and are variable in their appearance. They vary both in colour, from reddish brown to a greenish yellow shade, and also in the extent of the black marking on their forewings. They are nocturnal and are attracted to light.
Heterocrossa adreptella is a moth of the Carposinidae family. This species was long considered the New Zealand raspberry budmoth however this was a taxonomic misinterpretation of the type material used to describe this species. This error was corrected in 1988 with the New Zealand raspberry budmoth giving its own species name Heterocrossa rubophaga. H. adreptella is endemic to New Zealand and has been collected in the Wellington Botanic Garden and been observed resting on mānuka branches.
Pasiphila bilineolata is a moth in the family Geometridae. It is endemic to New Zealand and can be found in the North and South Islands. The species inhabits native forest and shrubland and the larvae feed on Hebe species. Adults are on the wing commonly from August to January but have been observed most months of the year and are attracted to light.
Pasiphila muscosata, the emerald pug moth, is a moth in the family Geometridae. It is endemic to New Zealand and has been found in the North, South and Stewart Islands. The larvae of this species are known to be present in January and live on Muehlenbeckia species including Muehlenbeckia australis. The larvae tends to be brown but it is variable in both colour and markings. The larvae of this species pupates in a loose cocoon on the ground and adult moths emerge in September. Adults are commonly on the wing until the following May. Although adults tend to be a deep emerald green colour this species is again variable and there is also an orange-yellow variety as well as intermediate forms. Adults are attracted to light and often rest during the day on tree trunks.
Epiphryne undosata, also known as the lacebark looper, is a moth of the family Geometridae. It is endemic to New Zealand and is found on both the North and South Islands. It inhabits native forest. The larvae feed on plant species in the genera Hoheria and Plagianthus. They pupate amongst dead leaves in a silk cocoon. The adult moths have been observed on the wing all year round but are most commonly seen from November until February. The adult moths are extremely variable in both their colour intensity and wing pattern.
Homodotis megaspilata, also known as the small hooked-tip looper moth, is a moth of the family Geometridae. It is endemic to New Zealand and can be found throughout the country. It is regarded as being common species. The preferred habitat of this species is native forest, scrub, coastal areas and domestic gardens. Larvae feed on the dead leaves of Geniostoma ligustrifolium and likely other native plants. Once mature the larvae will pupate on the ground forming a silken cocoon protected by hiding inside two leaves of its host plant. Adults are nocturnal and are on the wing from October to April. They are attracted to light. In appearance the adults of this species are extremely variable but can be distinguished from similar species as all variations have forewings with blunt hook shaped tips.
Agriophara colligatella, also known as the Olearia Skeletoniser, is a moth of the family Depressariidae. It is endemic to New Zealand and is found on both the North and South Islands. This species inhabits native scrub. Larvae feed on the leaves of species in the genus Olearia during the months of November and December. They then pupate amongst the old flowers and leaves of their host plant. Adults have been observed on the wing from August to September but are most common in January. It has been hypothesised that this species overwinters as an adult as it has been observed on the wing in late autumn and early winter. Adults are attracted to light.
Bityla defigurata is a moth of the family Noctuidae. It is endemic to New Zealand.
Asaphodes clarata is a species of moth in the family Geometridae. This species is endemic to New Zealand and has been found on the North and South Islands. The species inhabits open grassy areas, including tussock grasslands, in montane habitat. The larvae feed on the leaves of Ranunculus species. The adult moths are day flying and are on the wing from December to February and have been shown to pollinate Celmisia laricifolia and Hebe pinguifolia.
Chalastra pellurgata, also known as the brown fern moth or the pale fern looper, is a moth of the family Geometridae. This species was first described by Francis Walker in 1862. It is endemic to New Zealand and can be found throughout the country. It inhabits native forest. This species is extremely variable both in its larval and adult life stage. Larvae of this species are active during spring and summer. They feed on the fronds of fern species. C. pellurgata pupates by forming a thin cocoon on the soil amongst leaf litter and moss. Adults are on the wing throughout the year but are most common from September to March. During the day adult moths can be observed resting on dead fern fronds. They become active from dusk and are attracted to light.
Chalastra aristarcha, the silver fern moth, is a moth of the family Geometridae. This species was first described by Edward Meyrick in 1892. It is endemic to New Zealand and is found in the North Island. This species inhabits dense native forest. The larvae feed on the species host plant, the Silver fern, during spring. This species then pupates on top of leaf litter or moss on the ground. The pupation state lasts for approximately 6 weeks. Adult moths are on the wing from October until April but can sometimes also be seen during the winter months. Adults can be disturbed from silver ferns during the day or are seen on the wing at night particularly at Metrosideros perforata when in flower. Adults are attracted to light. It has been hypothesised that the range of C. aristarcha has restricted as a result of urban development and land conversion of its habitat.
Trachypepla contritella, the Kiwi Enigma, is a species of moth in the family Oecophoridae. Originally endemic to New Zealand this species can be found throughout that country. However, from 2012 this species has been also been recorded in the United Kingdom. The preferred habitat of T. conritella is New Zealand native forest and larvae of this species are litter leaf feeders. Adults are on the wing from November to February in New Zealand and are attracted to light.
Ischalis nelsonaria, also known as the angled fern looper, is a species of moth of the family Geometridae. It was first described in 1875. This species is endemic to New Zealand and has been observed in both the North and South Islands. I. nelsonaria inhabits native forest. The larval host of this species is Zealandia pustulata. Larvae have also been raised on Blechnum novae-zelandiae. Adult moths of this species are variable in appearance and are nocturnal. They have been observed on the wing throughout the year but are most frequently observed in February and March. They have been observed feeding on the flowers of Metrosideros diffusa.
Pseudocoremia colpogramma is a species of moth in the family Geometridae. This species was described by Edward Meyrick in 1936. It is endemic to New Zealand.
