The Rock and Pillar Range of high hills is located in the Maniototo, an area of inland Otago, New Zealand. They are surrounded by the Taieri River, which has its source in the range, flowing out across the scroll plain at Paerau, before almost doubling back on itself at Waipiata and flowing back along the other side through the Strath-Taieri. The town of Middlemarch lies close to the Taieri to the east of the range, and Patearoa lies to the northwest.

The Rock and Pillars are a horst range, caused by movement on two parallel faults uplifting the area in between. Thus, the range is characterised by a very flat top, with steep escarpments on either side. The Great Moss Swamp lies on the upper surface of the range. There is a persistent and highly unusual cloud formation associated with the range. This strange cloud formation, found only in one or two places in the world, is more or less stationary and is called the Taieri Pet by the local inhabitants. It is formed by high north-westerly winds being forced upward over the Rock & Pillar range. Big Hut, situated near the summit of the range, is available for public use.

The Rock and Pillar Range is the border separating the Central Otago District from the Dunedin City administrative area within the Otago Region.

The range takes its name from the rock formations that cover parts of it. The highest point in the range is Summit Peak or Summit Rock at 1,450 metres (4,760 ft). Several lower points include Stonehenge 1,380 metres (4,530 ft) and McPhee's Rock 1,013 metres (3,323 ft).

Fauna and Flora

The nationally endangered Burgan Skink is endemic to the Rock and Pillar range. [1] This range is also an area of narrow-range endemism for New Zealand endemic moths. [2] The moth species Ichneutica schistella can only be found in this area. [2]

Middlemarch is a small town in the Otago region of New Zealand's South Island. It lies at the foot of the Rock and Pillar Range of hills in the broad Strath-Taieri valley, through which flows the middle reaches of the Taieri River. Since local government reorganisation in the late 1980s, Middlemarch and much of the Strath-Taieri has been administered as part of Dunedin city, the centre of which lies some 80 km to the southeast. Middlemarch is part of the Taieri electorate, and is currently represented in parliament by Ingrid Leary. Middlemarch has reticulated sewerage but no reticulated water supply. A description of 1903, that "[T]he summer seasons are warm, but not enervating, and the winters cold, but dry" is still true today.

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

Ichneutica lithias is a moth of the family Noctuidae. This species is endemic to New Zealand. It is a small moth but distinctive as a result of the markings on its forewings. Although this species is widespread in the South Island, it has only been collected in the Rangipo Desert in the North Island. The species prefers habitat that is scrubland ranging in altitude from coastal to alpine. Adults are on the wing from October to April and larvae have been collected and reared on the New Zealand endemic plant species Melicytus alpinus.

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

Ichneutica averilla is a moth of the family Noctuidae. It is endemic to New Zealand. This species is found in the North Island at Mount Taranaki but is widespread throughout the South Island and Stewart Island. It prefers mountainous habitat but can be found down to sea level in the southern parts of the South Island. Adults of the species are on the wing between November and March. Larvae likely exist on a variety of herbaceous plants but have been recorded as feeding on species within the genus Plantago. This species is sometimes confused with I. mutas but can be distinguished from the latter on the basis of forewing colour as well as the absence of or an indistinct antemedian forewing line.

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

Ichneutica cuneata is a moth in the family Noctuidae. It is endemic to New Zealand. I. cuneata is found in and around the Tongariro National Park in the North Island and throughout the South Island. Specimens found in Tongariro National Park tend to be darker in appearance than South Island specimens but as their colour is variable, and antennae and genitalia of both species are consistent, they are not now regarded as a separate species. I. cuneata inhabits tussock grasslands and shrublands in alpine and subalpine zones. The adults are on the wing from December to April and can be found flying during the day. The life history of I. cuneata is unknown as are the specific host species of its larvae. However larvae of I. cuneata are said to feed on herbaceous plants. The adults of this species also pollinate native species such as Myosotis macrantha.

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

Ichneutica fibriata is a moth in the family Noctuidae. It is endemic to New Zealand. Specimens of this moth were first collected by Frederick Giles Gibbs. The species is similar in appearance to other species in the Ichneutica genus particularly I. eris but can be distinguished due to its larger size and more uniform light grey colour. I. fibriata also has a similar coloured thorax and head where as these two anatomical features may differ in colour shade in I. eris. Adults frequent alpine areas and are on the wing in November to January. The life history and the host species of the larvae of this species is unknown.

Taiari / Chalky Inlet is one of the southernmost fiords in Fiordland, in the southwestern corner of New Zealand's South Island and part of Fiordland National Park. As with the neighbouring fiords of Tamatea / Dusky Sound to the north and Rakituma / Preservation Inlet to the south, Taiari / Chalky Inlet is a complex fiord with many channels and islands along its roughly 28 km (17 mi) length. Most notably, this includes the sections Moana-whenua-pōuri / Edwardson Sound and Te Korowhakaunu / Kanáris Sound, which split at Divide Head in the middle of Taiari and each extend for roughly 10 km (6.2 mi) inland in a V-shape.

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

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

Ichneutica fenwicki is a moth of the family Noctuidae. This species is endemic to New Zealand and is found in the southern parts of the South Island and on Stewart Island. It is a distinctively coloured moth that is unlikely to be confused with closely related species. It is a spring flying moth being on the wing from September to November. The life history and host species of the larvae of I. fenwicki are unknown.

Ichneutica cornuta is a moth of the family Noctuidae. This species is endemic to New Zealand and is only found in the South Island, in and around the Southern Alps. I. cornuta is very similar in appearance to pale forms of I. arotis. It is easy to confuse the two species as their ranges overlap. Male I. cornuta can be distinguished as it has longer pectinations on the antennae and the female lacks the dark scaling that can be found on the thorax of the I. arotis. There are also subtle differences in the forewing patterns of the two species. The life history of this species is unknown as are the host species of its larvae. Adults are on the wing from January to April.

<i>Ichneutica virescens</i> Species of moth, also known as owlet moth

Ichneutica virescens is a moth of the family Noctuidae. It is endemic to New Zealand, and is found in the southern North Island and throughout the South Island. The species is found in alpine, sub-alpine, and down to sea-level in grassland habitats. Adults are on the wing from November through to April. The likely larval host may be grasses, but larvae have been reared on a range of plants. The adults are similar to I. panda, I. falsidica and I. nobilia, but is distinguished by size, wing colouration, and antennae formation.

Ichneutica lyfordi is a moth of the family Noctuidae. This species was named in honour of its first collector, Brian M. Lyford, and is endemic to New Zealand. It is only known from the Von Valley in the Otago Lakes area of the South Island. As at 2021, only the male of the species has been collected. The life history of this species is unknown as are the host species of its larvae. Adults are on the wing in February and are attracted to light.

Ichneutica prismatica is a moth of the family Noctuidae. This species is endemic to New Zealand. The species is ochreous coloured with distinctive pale streaks on its forewings and a white fringe on its hindwings. It is similar in appearance to I. paraxysta but I. prismatica is smaller, lighter bodied and has narrower wings. Also I. prismatica can only be found in the South Island where as I. paraxysta is only known from the North Island. I. prismatica has mainly be collected in the Central Otago region but has also been recorded in the Otago Lakes and the wider Dunedin regions. It inhabits tussock grasslands and wetlands. The life history of this species is unknown but the larval host species are found in the genus Chionochloa. Adults are on the wing in December and January and have been recorded as flying during the day.

Ichneutica haedifrontella is a moth of the family Noctuidae. This species is endemic to New Zealand. It is only known from scattered areas in the North and South Islands. In the North Island it has only been collected in the Pouakai Range in Taranaki. In the South Island it is known from the Nelson, Buller, North Canterbury, Otago Lakes and Fiordland regions. It inhabits alpine to subalpine zones. The life history of this species is unknown as are the host species of its larvae in the wild. Larvae have been reared on species in the Chionochloa genus. Adults are on the wing from December to February and are attracted to light. This species has a smaller dwarf form that can be found in the Pouakai Range and at Dart Hut.
