Uropetala Chiltoni
''Uropetala chiltoni'' (New Zealand mountain giant dragonfly) is a giant dragonfly in the family Petaluridae, endemic to New Zealand. The Māori name for giant dragonflies, ''kapokapowai'', means "water snatcher", alluding to the water-dwelling juvenile stage (nymph), which, like all dragonflies, has a long extendable jaw that shoots out to snatch prey. Description The second-largest New Zealand dragonfly species, ''Uropetala chiltoni'' has a body length of about 80 mm and wingspan of about 100 mm. ''Uropetala chiltoni'' can be distinguished from the similar ''Uropetala carovei'' by large pale blotches on its labrum (which in ''Uropetala carovei'' is all black'')'', and its black femur leg segments (which are brownish in ''Uropetala carovei''). It was described as a separate species in 1921, based on specimens collected at Cass and Arthur's Pass. Distribution This species is found only in New Zealand, in upland and sub-alpine parts of the South Island. It has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert John Tillyard
Robert "Robin" John Tillyard FRS (31 January 1881 – 13 January 1937) was an English–Australian entomologist and geologist. Early life and education Tillyard was the son of J. J. Tillyard and his wife Mary Ann Frances, née Wilson and was born at Norwich, Norfolk. He was educated at Dover College and intended to enter the army but was rejected on account of having suffered from rheumatism. He won a scholarship for classics at Oxford and another for mathematics at Cambridge, and decided to go to Queens' College, Cambridge. He graduated senior optime in 1903. He went to Australia in 1904 and was appointed second mathematics and science master at Sydney Grammar School. While working as a science master Tillyard found time to publish extensively on dragonflies. After nine years with Sydney Grammar School, he resigned and undertook a research degree in biology at Sydney University and took his research BSc degree in 1914. Career He was seriously injured in a railway accident ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod Leg
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schoenus (plant)
''Schoenus'' is a predominately austral genus of sedges, commonly known as bogrushes, or veldrushes in South Africa. Species of this genus occur mainly in South Africa (some 44 species), Australia (some 70 species) and Southeast Asia. Others are found in scattered locations worldwide, from Europe (2 species) to Asia, North Africa (1 species) and the Americas. Three species occur in the peatlands of southern South America, including '' S. antarcticus'' which is found in Tierra del Fuego, where it forms a component of hyperhumid Magellanic moorland. Taxonomic attention to the South African taxa, starting 2017, revealed a wealth of species. 24 species were transferred from '' Tetraria'' and '' Epischoenus'' into ''Schoenus'', and several new species were described. '' S. inconspicuus'', discovered on the outskirts of Cape Town, consists of only a few specimens.

Lake Wakatipu
Lake Wakatipu ( mi, Whakatipu Waimāori) is an inland lake (finger lake) in the South Island of New Zealand. It is in the southwest corner of the Otago region, near its boundary with Southland. ''Lake Wakatipu'' comes from the original Māori name . With a length of , it is New Zealand's longest lake, and, at , its third largest. The lake is also very deep, its floor being below sea level, with a maximum depth of . It is at an altitude of , towards the southern end of the Southern Alps / Kā Tiritiri o te Moana. The general topography is a reversed "N" shape or "dog leg". The Dart River / Te Awa Whakatipu flows into the northern end, the lake then runs south for 30 kilometres before turning abruptly to the east. Twenty kilometres (12.4 mi) further along, it turns sharply to the south, reaching its southern end further south, near Kingston. The lake is drained by the Kawarau River, which flows out from the lake's only arm, the Frankton Arm, east of Queenstown. Until ...

Lake Rotoiti (Tasman)
Lake Rotoiti, previously also known as Lake Arthur, is a lake in the Tasman Region of New Zealand. It is a substantial mountain lake within the borders of Nelson Lakes National Park. The lake is fed by the Travers River, water from the lake flows into the Buller River. The lake is surrounded by beech forest and is deep. Saint Arnaud is a small community at the northern end of the lake. The New Zealand Ministry for Culture and Heritage gives a translation of "little lake" for . The first European to see the lake was John Sylvanus Cotterell on 18 January 1843. Thomas Brunner and Charles Heaphy reached the lake in November 1843, and Heaphy named it Lake Arthur after Captain Arthur Wakefield, but the Māori name remained. For many years the lake formed part of Nelson politician and landowner John Kerr's beloved Lake Station - including Mt Robert. Kerr (who introduced Trout to the lake),drowned there with many believing his son Robert to be responsible. The lake and Mt Robert reve ...

South Island
The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers , making it the world's 12th-largest island. At low altitude, it has an oceanic climate. The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook at . The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and services. ...

Arthur's Pass (mountain Pass)
Arthur's Pass, a mountain pass ( above sea level) in the Southern Alps of the South Island of New Zealand, marks part of the boundary between the West Coast and Canterbury regions. Located 140 km from Christchurch and 95 km from Greymouth, the pass comprises part of a saddle between the valleys of the Otira River (a tributary of the Taramakau River in the west) and of the Bealey River (in the east). Arthur's Pass lies on the border of the Selwyn and Westland districts. A township of the same name (Arthur's Pass) lies about 5 km south of the mountain pass. The pass is named after Arthur Dudley Dobson and a memorial at the pass commemorates him. History For hundreds of years Māori had crossed the Southern Alps by every pass free of snow in the summer months. The reason for making this difficult journey was greenstone (''pounamu''), highly prized both for its hardness and beauty and found only on the West Coast of the South Island. By the time Europeans arrived, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labrum (arthropod Mouthpart)
The labrum is a flap-like structure that lies immediately in front of the mouth in almost all extant Euarthropoda. The most conspicuous exceptions are the Pycnogonida, which probably are chelicerate-relatives. In entomology, the labrum amounts to the "upper lip" of an insect mouth, the corresponding "lower lip" being the labium. The evolutionary origin, embryogenesis and morphological development of the labrum have proved to be by far the most controversial and challenging topic in the study of arthropod head structures. Embryonic nature and origin of the labrum The labrum is innervated in crustaceans and insects from the tritocerebrum (the back of the brain). However, in development, its embryonic primordium often appears at the anterior of the head and migrates backwards towards its adult position. Furthermore, it often appears as a bilobed structure, with a set of muscles, nerves and gene expression in many ways similar to that of an appendage. This evidence has been use ...

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized by a pair of large, multifaceted compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or ...

Uropetala Carovei
''Uropetala carovei'' (New Zealand bush giant dragonfly) is a giant dragonfly of the family Petaluridae, endemic to New Zealand. Its Māori name, ''kapokapowai (or kapowai)'' means "water snatcher", alluding to the water dwelling juvenile stage (nymph), which, like all dragonflies, has a long extendable jaw that shoots out to snatch prey. It is also known as Carové's Giant Dragonfly. Description Its yellow and black body can be up to long, with a wingspan up to , making it the largest dragonfly in New Zealand. Females are slightly larger than males. The bodies of both the female and male are dark brown, with pale spots on the abdomen and thorax. Males have petal-shaped appendages at the tip of the abdomen. ''Uropetala carovei'' can be distinguished from the similar '' Uropetala chiltoni,'' which occurs in the mountains of the South Island, by its all-black labrum (lacking the large pale blotch on ''Uropetala chiltoni),'' and its brown to yellowish leg femur segments (which ...
