Plecoptera is an order of insects, commonly known as stoneflies. Some 3,500 species are described worldwide, with new species still being discovered. Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and Lower Permian geological periods, while true stoneflies are known from fossils only a bit younger. Their modern diversity, however, apparently is of Mesozoic origin.
Aquatic insects or water insects live some portion of their life cycle in the water. They feed in the same ways as other insects. Some diving insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete.
Kiewa River, a perennial river that is part of the Murray catchment within the Murray-Darling basin, is located in the Alpine bioregion, in the Australian state of Victoria.
Mount Bogong,, located in the Alpine National Park and part of the Victorian Alps of the Great Dividing Range, is the highest mountain in Victoria, Australia, at 1,986 metres (6,516 ft) above sea level.
The Victorian Alps, also known locally as the High Country, is a large mountain system in the southeastern Australian state of Victoria. Occupying the majority of eastern Victoria, it is the southwestern half of the Australian Alps, the tallest portion of the Great Dividing Range. The Yarra and Dandenong Ranges, both sources of rivers and drinking waters for Melbourne, are branches of the Victorian Alps.
The Bogong High Plains, part of the Victorian Alps of the Great Dividing Range, are a section of plains located in the Alpine National Park in the Australian state of Victoria and are situated south of Mount Bogong.
The Cordulegastridae are a family of Odonata (dragonflies) from the suborder Anisoptera. They are commonly known as spiketails. Some vernacular names for the species of this family are biddie and flying adder. They have large, brown or black bodies with yellow markings, and narrow unpatterned wings. Their bright eyes touch at a single point, and they can be found along small, clear, woodland streams, flying slowly 30 to 70 cm above the water. When disturbed, however, they can fly very rapidly. They usually hunt high in forest vegetation, and prefer to capture prey resting on leaves or branches.
Riekoperla darlingtoni, the Mount Donna Buang wingless stonefly, is a species of stonefly in the family Gripopterygidae, which is endemic to Australia.
The Kiewa Valley Highway is a minor highway of 80 kilometres (50 mi) which traverses the Kiewa Valley near the alpine regions of Victoria, Australia. In the 1950s the road was sealed and realigned to Mount Beauty to permit the transport of materials for the construction of the Kiewa Hydroelectric Scheme. From Mount Beauty the road continues as the Bogong High Plains Road, a winding and twisty route via the alpine resort of Falls Creek, which terminates at its junction with the Omeo Highway at Shannonvale south of Glen Valley.
Victoria is the southernmost mainland state of Australia. With an area of 227,444 km2 (87,817 sq mi), it is Australia's sixth largest state/territory, comparable in size to the island of Great Britain or the U.S. state of Utah. It is bound to the northwest by South Australia, directly north by New South Wales, and also shares a maritime border with Tasmania across the Bass Strait to the south. Most of Victoria's northern border lies along the Murray River. The eastern half of the state is dominated by the Australian Alps and the surrounding highlands of the Great Dividing Range, which also to a lesser extent extend far into the west of the state and ease off after The Grampians. By comparison the north and northwest of the state is extremely flat with little prominence.
Chloroperlidae are a family of stoneflies, commonly known as green stoneflies, with more than 200 species and 22 genera. They appear green to yellow in colour, and are popularly used among fisherman as bait for trout fishing. Green stoneflies live in the benthic zone of the cold streams and rivers of five continents and four zoogeographical regions, emerging from the water to live in the riparian zone as adults. They are sensitive to pollutants, making them an indicator species for determining the quality of water bodies. Chloroperlidae are hemimetabolous, having no pupal stage, but instead hatch from eggs as nymphs and mature directly into adults. They are omnivorous, feeding on small organisms and plant particles, and become more carnivorous as they mature. The classification of Chloroperlidae is contested, with some believing that they should be considered as members of different orders, as opposed to the order Plecoptera that they currently belong to.
Coxoplectoptera or "chimera wings" is an extinct order of stem-group mayflies containing one family, Mickoleitiidae. Together with mayflies (Ephemeroptera), Coxoplectoptera are assigned to the clade Heptabranchia.
Maisie Carr was an innovative Australian ecologist and botanist who contributed much to the understanding of the uniqueness of Australian plants and their environmental systems.
Eustheniidae is a family of insects in the order Plecoptera, the stoneflies. They are native to Australia, New Zealand, and Chile.
Thaumatoperla is a genus of insect in the family Eustheniidae containing four species of stonefly, all endemic to the Victorian alpine area of Australia.
Thaumatoperla flaveola is a species of stonefly in the genus Thaumatoperla. They are endemic to the Mount Buller–Mount Stirling area of the Victoria alps, Australia.
Capnia lacustra, also known as the Lake Tahoe benthic stonefly, is a species of insect in the family Capniidae. It was first described by S.G. Jewett in 1965 and is the only stonefly known to spend its entire adult life underwater.
Stenoperla prasina is a species of stonefly belonging to the family Eustheniidae. This species is endemic to New Zealand and is classified as "Not Threatened" under the New Zealand Threat Classification System. It is found on the North, South and Stewart Island / Rakiura Islands as well as on Little Barrier Island. Although adults of this species are most often coloured bright green, this species can be coloured yellow. This species inhabits clean, cold, running streams and rivers with stony bottoms within native bush. It is a known indicator of water quality. The larvae eat plant detritus and other aquatic insects while the adult insects feed on sooty mould fungi as well as other plant matter. The adults of this species are a known food source for New Zealand long tailed bats. Adults have been dissected and have been found to have been carrying Nematomorpha and trematode parasites. The New Zealand Department of Conservation classifies this species as "Not Threatened". In 2022 a specimen of this species was the 5 millionth specimen to be digitised in the Natural History Museum, London collection.
Eusthenia spectabilis is a very large species of stonefly in the family of giant stoneflies, Eustheniidae. At 4 cm (1.6 in) Eusthenia spectabilis is the largest member of the genus and emerges later than other similar species.
Zelandoperla fenestrata is a widespread endemic New Zealand ‘long-tailed’ stonefly that is often abundant in high-gradient stony streams, from near sea-level up to alpine elevations. The species name 'fenestrata' refers to the window-like rectangular patterning visible on the wings of non-melanic adult specimens.
