Griseargiolestes Albescens
''Griseargiolestes albescens'' is a species of Australian damselfly in the family Megapodagrionidae The Megapodagrionidae are a family Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-bei .... It is commonly known as a coastal flatwing. Coastal flatwings are medium sized damselflies; males are about 37 mm in length and the slightly smaller females are about 34 mm. They have a bronze-black colour marked with pale yellow, adult males are strongly pruinescent - their bodies and tip of their tails are covered with a fine, white, powdery layer. They are only found in south-eastern Queensland and north-eastern New South Wales, inhabiting creeks and streams, swampy areas, boggy seepages and lakes, and will often rest on the lower parts of plants. Like other flatwing damselflies, coastal flatwings rest with their win ... [...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] |
Biodiversity Heritage Library
The Biodiversity Heritage Library (BHL) is the world’s largest open access digital library for biodiversity literature and archives. BHL operates as worldwide consortiumof natural history, botanical, research, and national libraries working together to address this challenge by digitizing the natural history literature held in their collections and making it freely available for open access as part of a global “biodiversity community.” The BHL consortium works with the international taxonomic community, publishers, bioinformaticians, and information technology professionals to develotools and servicesto facilitate greater access, interoperability, and reuse of content and data. BHL provides a range of services, data exports, and APIs to allow users to download content, harvest source data files, and reuse materials for research purposes. Through taxonomic intelligence tools developed bGlobal Names Architecture BHL indexes the taxonomic names throughout the collection, allowing ...

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, but the ...

A 2013 phylogenetic analysis pares down this family into only three genera, and numerous other genera are now placed in different families, including Amanipodagrionidae, Argiolestidae, Heteragrionidae, Hypolestidae, Lestoideidae, Mesagrionidae, Mesopodagrionidae, Philogeniidae, Philosinidae, Protolestidae, Rhipidolestidae, Tatocnemididae, and Thaumatoneuridae.

Australian Faunal Directory
The Australian Faunal Directory (AFD) is an online catalogue of taxonomic and biological information on all animal species known to occur within Australia. It is a program of the Department of Climate Change, Energy, the Environment and Water of the Government of Australia. By May 12, 2021, the Australian Faunal Directory has collected information about 126,442 species and subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species .... It includes the data from the discontinued ''Zoological Catalogue of Australia'' and is regularly updated. Started in the 1980s, it set a goal to compile a "list of all Australian fauna including terrestrial vertebrates, ants and marine fauna" and create an "Australian biotaxonomic information system".''Commonwealth Record'', Volume 5, Issues 26-34, p. 1 ...

Australian Biological Resources Study
Australian Biological Resources Study (ABRS) is a project undertaken by Parks Australia Division of Australia's Department of the Environment, Water, Heritage and the Arts (DEWHA). Background ABRS was founded in 1973 from the recommendations of a 1972 Senate Select Committee report on Wildlife Conservation. Its purpose is to collate from the many libraries, museums and other collections the taxonomy of Australia's estimated 2 million species of flora and fauna, including aquatic species. These represent almost 20% of the earth's biodiversity, 80% of which are unique to Australia. ABRS has undertaken active funding for taxonomic research of Australia's biodiversity and is internationally recognised for its extensive data bases and publications. Publications The most important outputs of the ABRS has been the publication of the multi-volume ''Flora of Australia'' and '' Fauna of Australia'' series. Other output includes ''The Banksia Atlas'' and the "Platypus" database pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pruinescence
Pruinescence , or pruinosity, is a "frosted" or dusty-looking coating on top of a surface. It may also be called a pruina (plural: ''pruinae''), from the Latin word for hoarfrost. The adjectival form is pruinose . Entomology In insects, a "bloom" caused by wax particles on top of an insect's cuticle covers up the underlying coloration, giving a dusty or frosted appearance. The pruinescence is commonly white to pale blue in color but can be gray, pink, purple, or red; these colors may be produced by Tyndall scattering of light. When pale in color, pruinescence often strongly reflects ultraviolet. Pruinescence is found in many species of Odonata, particularly damselflies of the families Lestidae and Coenagrionidae, where it occurs on the wings and body. Among true dragonflies it is most common on male Libellulidae (skimmers). In the common whitetail and blue dasher dragonflies (''Plathemis lydia'' and ''Pachydiplax longipennis''), males display the pruinescence on the back of th ...
