Helastia Cinerearia
''Helastia cinerearia'' is a moth of the family Geometridae. It is endemic to New Zealand and can be found in the North, South and Stewart Islands as well as on the Mercury and Chatham Islands. The preferred habitat of ''H. cinerearia'' includes urban gardens, various types of forest and sub alpine habitats. The larval host is lichen on rocks. The adult moths are on the wing all year round but are most commonly observed from September until February. Adult moths are nocturnal and have been observed feeding from and likely pollinating '' Hebe salicifolia'', ''Hoheria lyallii'' and ''Leptospermum scoparium''. Taxonomy This species was first described by Edward Doubleday in 1843 and named ''Cidaria cinerearia''.

In 1939 Louis Beethoven Prout placed this species in the genus ''Larentia''. In 1971 J. S. Dugdale placed this sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helastia Alba
''Helastia alba'' is a moth of the family Geometridae. This species is endemic to New Zealand and is found only in the South Island. This species inhabits native forest or scrubland and can be observed in montane to subalpine Nothofagus dominant forests. It has also been observed at lower altitudes in native podocarp forests. Larvae of this species have been raised on mosses. Adults are on the wing from November to January and are nocturnal. This species is very similar in appearance to other species in the genus ''Helastia, but'' specimens can be distinguished by the dissection of their genitalia.

Helastia Plumbea
''Helastia plumbea'' is a moth of the family Geometridae. This species is Endemism, endemic to New Zealand and is found in both the North Island, North and South Island, South Islands. The species inhabits stream and river banks in montane to subalpine terrain. Adults are on the wing from October to April and are nocturnal and attracted to light. The life history of this species is, at 2024, poorly known but the larval host plants are likely mosses, herbs or possibly lichens. Taxonomy This species was first described by Alfred Philpott in 1915 using four specimens collected in Queenstown, New Zealand, Queenstown in November and was originally named ''Xanthorhoe plumbea''. George Hudson (entomologist), George Hudson discussed this species under that name in his book ''The Butterflies and Moths of New Zealand.'' Philpott illustrated the male genitalia of this species in 1928. Louis Beethoven Prout, L. B. Prout, in 1939, discussed this species as a synonym of ''Xanthorhoe infanta ...

Helastia Cymozeucta
''Helastia cymozeucta'' is a moth of the family Geometridae. It was first described by Edward Meyrick in 1913. This species is endemic to New Zealand and is found in both the North and the upper parts of the South Island. The adults of this species have been observed on the wing from November to January as well as in March. Taxonomy This species was first described by Edward Meyrick in 1913 using specimens collected by George Hudson at Ohakune and named ''Xanthorhoe cymozeucta''. Hudson used this same name when he discussed and illustrated the species in his 1928 book The butterflies and moths of New Zealand. In 1939 Hudson, thinking he was describing a new species, also named it ''Xanthorhoe maoriaria''. In 1971 J. S. Dugdale placed both ''X. cymozeucta'' and ''X. maoriaria'' in the genus ''Helastia''.

Helastia Christinae
''Helastia christinae'' is a moth of the family Geometridae. It was Species description, first described by Robin C. Craw in 1987. This species is Endemism, endemic to New Zealand and has been confirmed as being observed at Dunedin, and the Central Otago and Otago Lakes areas. ''H. christinae'' inhabits subalpine to lowland areas frequenting river banks and stream sides. The food source for the larvae of this species are lichens. The adults of this species are on the wing in October to December. They are nocturnal and are attracted to light. Adult moths can be distinguished from similar appearing species in the genus ''Helastia'' as they have a "conspicuous transverse grey-ish white median band on the upper side of the forewing".

Helastia Corcularia
''Helastia corcularia'' is a moth of the family Geometridae. This species is endemic to New Zealand and is found only in the South Island and the Chatham Islands. It inhabits a wide variety of habitats including native forest and scrubland, gardens, parks, subalpine and coastal areas. Larvae feed on herbs, lichen and moss. The adults of the species are on the wing from September until May and are nocturnal and attracted to light. ''H. corcularia'' is considered an orchard and pack house contaminant. Taxonomy This species was first described by Achille Guenée in 1868 using a specimen collected in Christchurch by Richard William Fereday and named ''Larentia corcularia''. In the same publication and thinking he was describing another new species, Guenée also named this species ''Larentia infantaria''. Robin C. Craw when revising this species in 1987 synonymised ''L. infantaria with L. corcularia''. In 1877 Arthur Gardiner Butler synonymised ''H. corcularia'' with the species ''H ...

Helastia Cryptica
''Helastia cryptica'' is a moth of the family Geometridae. It was Species description, first described by Robin C. Craw in 1987. This species is Endemism, endemic to New Zealand and is found from mid Canterbury south. This preferred habitat of ''H. cryptica'' is native forest and scrub at altitudes ranging from lowland to subalpine. It has also been observed in human modified habitat. The larvae of this species has been observed on ''Melicytus alpinus'', likely feeding on perched dead leaves and have been hypothesised as feeding on epiphytic mosses. Adults are nocturnal and are on the wing from November until January. Externally this species is indistinguishable from its close relative ''Helastia cymozeucta, H. cymozeucta.'' However the distribution of these two species can assist in the correct identification of specimens. Taxonomy This species was first described by Craw in 1987. The male holotype, collected by Craw near the River Jordan in Paradise, New Zealand, Paradise, Ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helastia Semisignata
''Helastia semisignata'' is a moth of the family Geometridae. This species is Endemism, endemic to New Zealand and is only found in the North Island. The life history of this species is in need of further investigation as sources differ about what plants host the larvae. Adults are on the wing commonly from October until March. Taxonomy It was first described by Francis Walker (entomologist), Francis Walker in 1862 using specimens collected by A. Sinclair in Auckland and originally named ''Larentia semisignata''. In 1877 Arthur Gardiner Butler synonymised ''Cidaria dissociate'' and ''Cidaria semisilata'' with ''L. semisignata''. In the same publication Butler also mistakenly synonymised ''Larentia corcularia'' with ''L. semisignata''. This taxonomic error was correct by R. C. Craw in 1987. In 1912 Louis Beethoven Prout, L. B. Prout placed this species in the genus ''Xanthorhoe''. This placement was followed by George Hudson (entomologist), George Hudson in his 1928 book ''The b ...

Helastia Mutabilis
''Helastia mutabilis'' is a species of moth of the family Geometridae. It is endemic to New Zealand, where it is known from both the North and South Islands. It inhabits native forest at lower altitudes and its larval host are moss species in the genus ''Racomitrium.'' This species is nocturnal and is attracted to light.

Helastia Farinata
''Helastia farinata'' is a moth of the family Geometridae. It was first described by William Warren in 1896. This species is endemic to New Zealand and is found in the North Island. ''H. farinata'' inhabits shady and damp forest ravines. Taxonomy It was first described by William Warren in 1896 using specimens collected by George Hudson in Wellington and named ''Xanthorhoe farinata''.
