Chlorolestes Draconicus
''Chlorolestes draconicus'', the Drakensberg malachite, is a species of damselfly in the family Synlestidae. Distribution and status This species has a restricted range in the Drakensberg mountains of Lesotho and South Africa. Its conservation status has been assessed as Least Concern as much of its range falls within the uKhahlamba / Drakensberg Park. Habitat Its natural habitat is rocky streams at high altitude (1700–3000 m). Identification Where ''Chlorolestes draconicus'' is found, it is usually outnumbered by the similar ''Chlorolestes fasciatus''. Key differences between these species are the shape of the antehumeral stripe and the shape of the appendages. ''Chlorolestes draconicus'' is also larger and darker than ''Chlorolestes fasciatus''.

Boris Balinsky
Borys Ivanovych Balinsky (23 September 1905 – 1 September 1997) was a Ukrainian and South African biologist, embryologist, entomologist, professor of Kyiv University and University of the Witwatersrand. Pioneer researcher in the field of experimental embryology, electron microscopy and developmental biology. He was author of popular textbook in embryology ''An Introduction to Embryology''. Balinsky was born 23 September 1905, in Kyiv, Russian Empire (now Ukraine). He was a student of Ivan Schmalhausen and one of the first to experimentally induce organogenesis in amphibian embryos. Balinsky was a full university professor and the deputy director of the Institute of Biology in Kyiv (now I. I. Schmalhausen Institute of Zoology) at 28 years of age. He became a recognized expert in fish and amphibian development. Being a victim of Soviet repressions, he remained under German occupation during World War II and fled to Poznań, Poland and later Munich, Germany. Balinsky briefly w ...

Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, bu ...

Lesotho
Lesotho ( ), officially the Kingdom of Lesotho, is a country landlocked as an enclave in South Africa. It is situated in the Maloti Mountains and contains the highest mountains in Southern Africa. It has an area of over and has a population of about million. It was previously the British Crown colony of Basutoland, which declared independence from the United Kingdom on 4 October 1966. It is a fully sovereign state and is a member of the United Nations, the Commonwealth of Nations, the African Union, and the Southern African Development Community. The name ''Lesotho'' roughly translates to "land of the Sotho". History Basutoland Basutoland emerged as a single polity under King Moshoeshoe I in 1822. Moshoeshoe, a son of Mokhachane, a minor chief of the Bakoteli lineage, formed his own clan and became a chief around 1804. Between 1820 and 1823, he and his followers settled at the Butha-Buthe Mountain, joining with former adversaries in resistance against the ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of .

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evalua ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stream
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are importan ...

Odonata Of Africa
Odonata is an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic, though members of their total group, Odonatoptera, first appeared in Late Carboniferous. The two common groups are distinguished with dragonflies, placed in the suborder Epiprocta, usually being larger, with eyes together and wings up or out at rest, while damselflies, suborder Zygoptera, are usually smaller with eyes placed apart and wings along body at rest. All Odonata have aquatic larvae called naiads (nymphs), and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their legs are specialised for catching prey. They are almost entirely insectivorous. Etymology and terminology Fabricius coined the term ''Odonata'' in 1793 from the Ancient Greek ( Ionic form of ) 'tooth'. One hypothesis is that it was because their maxillae are notably toothed. Most insects also have toothed mandibles. The word ...
