Hierodoris atychioides (also known as the gregarious tineid) is a moth of the family Oecophoridae. [1] [4] It was described by Arthur Gardiner Butler in 1877. The female holotype specimen held at the Natural History Museum, London. This species is endemic to New Zealand, and can be found in the North, South and Stewart Islands. The larvae form webs of silk attached to frass and leaves on their hosts in which they shelter, often in the company of other larvae in their species. Their feeding habits have not been observed in detail but Hoare hypothesises the larvae may feed on dead or dying leaves. The larvae feed on a wide range of trees and shrubs, including Dacrydium cupressinum , Prumnopitys taxifolia , Dacrycarpus dacrydioides , Libocedrus bidwillii , Cupressus macrocarpa , Leptospermum scoparium , Kunzea ericoides , Ozothamnus leptophyllus , Abies , Picea , Pinus and Thuja species. Although they are regarded as a pest of exotic forests in New Zealand, the economic damage the larvae cause is minimal and they tend to be controlled only by their natural enemies. Larval enemies include the parasitic flies Trigonospila brevifacies and Pales funesta as well as parasitic wasps including Xanthopimpla rhopaloceros. The adult moths are day flying and are most common during the months of December and January. This species is variable in appearance as larvae, pupa and as adults, and it has been hypothesised that it is in the process of speciation.
This species was first described by Arthur Gardiner Butler in 1877 and named Tachyptilia atychioides. [5] [3] Butler used specimens sourced from James Hector (who collected in Dunedin) and John Davies Enys (who collected in Christchurch) but did not state a type locality. [5] [2] In 1888 Edward Meyrick placed this species within the Heliostibes genus. [6] In 1939 George Hudson synonymised both Heliostibes gregalis and Heliostibes barbarica with H. atychoioides. [7] In 1988 J. S. Dugdale placed this species within the genus Hierodoris. [2] This placement was confirmed by Robert Hoare in 2005. [3] The female holotype specimen is held at the Natural History Museum, London. [2]
M. K. Kay described the larvae of this species as follows:
Mature caterpillars are about 15 mm long and generally brown in colour although some may be quite light. The head is brown with black markings and immediately behind the head the upper surface of the next two segments is shiny, hardened and black. A white stripe extends along the back from the head to the last abdominal segment and separates paired brown spots on each segment. On dark specimens along each side there is also a pair of irregular whitish lines with dark spots between. Segments without legs have four brown spots on the underside. [8]
Butler described the adults of the species as follows:
Primaries above purplish brown; discoidai cell white, crossed by a large central subquadrate black spot, terminated by a smaller black spot; a small white spot beyond the cell, and a discal arched white line; apex bronzy brown; fringe brown, whitish towards apex; secondaries coppery brown, two sordid whitish longitudinal and fringe white, the latter brownish at anal angle; body above dark brown, collar and prothorax varied with ochraceous; hind margins of tegulae fringed with whitish; abdomen with whitish hind margins to the segments : primaries below bronzy-brown, pale towards the base, crossed towards apex by a series of ill-defined whitish dots, fringe greyish; secondaries sordid white, shining, clouded (excepting at apex and outer border) with grey; body below pearly whitish; tibiae and tarsi of legs above banded with black. [5]
The wingspan of the adults of this species is between 14–20 mm. [3] The hindwings are dark brown. [3]
It can be distinguished from H. callispora as it does not have the metallic head and thorax of that species. It is also different in appearance from H. gerontion as H. atychoioides has a hindwing with less white on it and a smooth labial palp. Finally it is a smaller moth that the dark forms of H. illita and does not have the pale streaks on that species' hind wings. [3] H. atychoioides is variable in appearance as a larva, pupa and as an adult. [8] Depending on the larval host, the adults of this species can show distinct differences in wing pattern as well as in their size. [3] For example if the larvae have been reared on rimu the adults can have a small reddish-marked appearance where as if reared on Libocedrus bidwillii larvae can produce a larger reddish adult moth. [3] As a result of this, it has been hypothesised that this species may be in the process of speciation. [3] However it has also been argued that the currently differences in appearance merge gradually from one to another in a continuous series and cannot be morphologically separated and therefore do not yet merit taxonomic separation. [3]
This species is endemic to New Zealand and is found throughout the North, South and Stewart Islands. [4] [3] However this species is regarded as being uncommon in Christchurch. [9]
The larvae form webs of silk attached to frass and the leaves of their hosts in which they shelter, often in the company of other larvae in their species. [3] Their feeding habits have not been observed in detail but Hoare hypothesises the larvae may feed on dead or dying leaves. [3] The larvae will attempt to withdraw further into its shelter or alternatively will fall to the ground if disturbed. [8] Once the larva is mature it pupates within its silken nest and then takes three weeks to metamorphosise. [8] [9] This species appears to have an annual life cycle. [9] The adult moth is day flying and is most common during the months of December and January. [8]
The larvae feed on a wide range of trees and shrubs, including Dacrydium cupressinum, Prumnopitys taxifolia, Dacrycarpus dacrydioides , Libocedrus bidwillii , Cupressus macrocarpa , Leptospermum scoparium , Kunzea ericoides , Ozothamnus leptophyllus , Abies , Picea , Pinus and Thuja species. [3]
The larvae of this species are susceptible to both fungal disease and parasitic insects. [8] Both Trigonospila brevifacies and Pales funesta , two species of fly, are known to parasitize H. atychioides. [8] H. atychioides are also parasitized by the wasp Xanthopimpla rhopaloceros , as well as wasp species in the Campoplex, Aucklandella and Goniozus genera. [8] It has been hypothesised that these natural parasites as well as wasps introduced as biocontrol agents may have caused the scarcity of this moth in Christchurch. [9]
Although this species is regarded as a pest of exotic forests in New Zealand, because the damage it does is limited, it is normally controlled by its natural enemies rather than by chemicals. [8] However this species can cause ornamental plants to be defoliated and as a result gardeners may resort to spraying insecticide to kill the feeding larvae. [8]
Kupea is a monotypic moth genus of the family Crambidae described by Alfred Philpott in 1930. It contains only one species, Kupea electilis, also known as Kupe's grassmoth, which is endemic to New Zealand. This species has only been recorded at Kaitorete Spit. The larvae feed on Zoysia minima and exist in a cocoon constructed of silk and sand. Adults are on the wing from March to April. It has been hypothesised that the adults are active at twilight. It is classified as Nationally Vulnerable by the Department of Conservation. The female of the species was first discovered in 2012.
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.
Hierodoris illita is a moth of the family Oecophoridae. It is endemic to New Zealand and is found in both the North and South Islands. However this species has not been recorded at Stewart Island / Rakiura.
Hierodoris electrica is a moth of the family Oecophoridae. It was described by Edward Meyrick in 1889. It is endemic to New Zealand, where it has been reported from the northern and southern parts of the South Island. The larva of H. electrica has yet to be described. The wingspan is between 15 and 16.5 mm. The ground colour of the forewings is dark brown, with narrow yellow scales overlaying this base colour. The hindwings are brown. The known larval host species is Olearia nummulariifolia.
Schiffermuelleria orthophanes is a moth of the family Oecophoridae. It is endemic to New Zealand. It is classified as critically endangered by the Department of Conservation.
Hierodoris iophanes is a moth of the family Oecophoridae. It was described by Edward Meyrick in 1912. This species can be distinguished from others in its genus by the purple metallic colouration as well as the blue-white mark on its forewings. It is endemic to New Zealand, where it has been recorded from Auckland to Southland. This species inhabits native forest or scrub, with the adults preferring open glades. They are known to be on the wing from November until February and fly during daylight hours, being active on hot sunny days. Larvae feed on the interior of twigs of Prumnopitys ferruginea. The twigs had evidence of oviposition scars of cicadas and the larvae were collected in October after reddish-brown frass indicated their location within the twigs.
Hierodoris stella is a species of moth in the family Oecophoridae. This species is endemic to New Zealand and occurs in Auckland, Taranaki, Hawkes Bay, Bay of Plenty and Wellington. As at 2005 the larvae of this species is unknown as is its host plant. The adult moth frequents forest and are on the wing in January and February. It is classified as "At Risk, Relict'" by the Department of Conservation.
Hierodoris bilineata is a species of moth in the family Oecophoridae. It is endemic to New Zealand. This species is classified as "At Risk, Naturally Uncommon" by the Department of Conservation. It is possible that this species gives birth to live young rather than lay eggs as is the norm.
Hierodoris polita is a species of moth in the family Oecophoridae. It is endemic to New Zealand and is found only in the Central Otago region and in the Dunedin area. As at 2005 the larvae have yet to be identified. However it is possible that a specimen may have been collected in leaf litter thus leading to the hypothesis that the species may be a detritivore. The adults of this species prefer open habitat and have mainly been collected on south-facing rocky bluffs. The adult moths are on the wing in October, November and January to March. This species is classified as "At Risk, Naturally Uncommon" by the Department of Conservation.
Hierodoris callispora is a moth of the family Oecophoridae. It is endemic to New Zealand and can be found throughout the country from south of the Bay of Plenty. This species inhabits native beech forest. Adults of the species have been found where Muehlenbeckia is common. Adults have also been collected from the flowers of Kunzea ericoides. However the larval host is unconfirmed although it has been hypothesised that larvae of this species feed on Kunzea ericoides flowers. Adults of this species can be distinguished by its orange ruff that contrasts with its dark head and thorax. There is a colour form that exists that has orange scales and an orange coloured fringe on the hindwing. Adults have been collected in December and January and are day flying but are also attracted to light at night. A female specimen has been found with a larva in her oviduct suggesting that this species may give birth to larval young.
Hierodoris eremita is a moth of the family Oecophoridae. It is endemic to New Zealand and found in the areas around Aoraki / Mount Cook and Westland Tai Poutini National Park areas. This species inhabits alpine herbfields at altitudes of around 900–1400 m. Larvae are said to have been reared on the leaves of plants in the Celmisia genus. Pupation happens on the host plant. The adults of this species is on the wing between December and June. This species is day flying.
Hierodoris frigida is a moth of the family Oecophoridae. It is endemic to New Zealand and is only found in the South Island. This species is found in two parts of that island, the Nelson/Tasman area and the Mackenzie, Otago and Dunedin areas in the southern part of the island. Although similar to H. iophanes this species can be distinguished as H. frigida has white bands on its forewings and the metallic coloured areas differ in placement. Segment 2 on the labial palp is entirely yellow and enables this species to be distinguished from the similar appearing species H. polita and H. torrida. Larvae have been collected amongst leaf litter from beneath species within the genus Thymus. It prefers open and shrubland habitats and adult moths have been observed flying close to the soil underneath Leptospermum scrub.
Hierodoris gerontion is a moth of the family Oecophoridae. It is endemic to New Zealand and is found in the alpine zones of the mountain ranges in Central Otago. This species prefers habitat near seepages and is also common in fellfields. H. gerontion is variable in appearance with the hindwings varying in appearance from white to a darkened brownish shade. It can be distinguished from other species in the Hierodoris genus as on the second segment of the labial palpi it has sub-erect scales giving the appearance of a shaggy beard. The larvae of this species has yet to be described.
Hierodoris pachystegiae is a moth of the family Oecophoridae. It is endemic to New Zealand and has only been collected at Kaikōura. The larval host are plants in the genus Pachystegia which is found only in the Marlborough region. The larvae of this species have yet to be described from life but the adults of this species are predominantly grey in colour. The forewings of this species have silver markings similar to that of H. electrica.
Hierodoris squamea is a moth of the family Oecophoridae. It is endemic to New Zealand and is found in the mountains of Fiordland as well as the Olivine Range in south Westland. This species has a wingspan of between 12 and 13 mm and can be distinguished from similar species as it is very small in size, has a reduced eyespot on its forewings, clearly visible through Scanning Electron Microscope preparations, and has orange-yellow scales overlaying its dark forewing. It prefers open country of tussock grasslands and herbfields at high altitudes. As at 2005 the larvae are unknown. Adults are on the wing in January.
Hierodoris s-fractum is a moth of the family Oecophoridae. It is endemic to New Zealand and can be found only in the southern parts of the South Island. The male is larger than the female. This species is very similar in appearance to H. eletrica however H. s-fractum has an interrupted silver S-mark on the forewing and longer labial palps. The larvae has not yet been described. Hoare hypothesised that the larvae of this species likely feeds on leaf-litter. The species seems to prefer open dry areas and can be found in native shrub and gorse.
Hierodoris insignis is a species of moth in the family Gelechiidae. It is endemic to New Zealand and has been found in the Nelson/Tasman districts. The larvae are leaf miners and are hosted by Celmisia species. Adults are on the wing in January. It is likely that this species belongs to another genus and as such this species is also known as Hierodoris (s.l.) insignis or 'Hierodoris' insignis.
Hierodoris stellata is a species of moth in the family Plutellidae. It is endemic to New Zealand and is found in Fiordland and Dunedin. This species has been found in coastal native forest. Larvae feed on Astelia flower-spikes and adults are on the wing in late December and January. It has been stated that this species belongs to the genus Charixena however this placement has yet to be published. As such this species is currently known as Hierodoris (s.l.) stellata or 'Hierodoris'stellata.
Trachypepla conspicuella is a species of moth in the family Oecophoridae. It is endemic to New Zealand and is found in both the North and South Islands. It is similar in appearance to its close relative T. euryleucota but tends to be paler. Its colouration imitates bird droppings. Larvae feed on leaf litter. Adults of this species are on the wing from November to February and have been observed resting on fences and walls.
Chrysorthenches virgata is a species of moth in the family Plutellidae. It was first described by Alfred Philpott in 1920. It is endemic to New Zealand and has been found in the North, South and Chatham Islands at altitudes ranging from sea-level up to approximately 1000 m. This species inhabits areas where its larval host plants, Libocedrus bidwillii and Cupressus macrocarpa are common. The larvae feed on the leaves of their hosts from under a silk shelter and pupate in a cocoon of thick silk covered in frass. Adult moths are on the wing from September to February as well as in April and June.
