Aciagrion Fragilis
''Aciagrion fragilis '' is a species of damselfly in the family Coenagrionidae, commonly known as a blue slim. It is a small, slender damselfly, the male is blue and black. It has been recorded from northern Australia, New Guinea and the Lesser Sunda Islands in Indonesia, where it inhabits still waters and swamps. Etymology The species name ''fragilis'' is a Latin word meaning fragile, or easily broken. In 1906, Robin Tillyard named this species probably in contrast to other members of the genus ''Ischnura'', where it had been provisionally placed.

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] |
Odonata Of Asia
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 wor ...

Insects Described In 1906
Insects (from Latin ') are pancrustacean Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes and one pair of antenna (biology), antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of Extant taxon, extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all Natural environment, environments, although only a small number of species reside in the oceans, which are dominated by ...

Taxa Named By Robert John Tillyard
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lesser Sunda Islands
The Lesser Sunda Islands or nowadays known as Nusa Tenggara Islands ( id, Kepulauan Nusa Tenggara, formerly ) are an archipelago in Maritime Southeast Asia, north of Australia. Together with the Greater Sunda Islands to the west they make up the Sunda Islands. The islands are part of a volcanic arc, the Sunda Arc, formed by subduction along the Sunda Trench in the Java Sea. A bit more than 20 million people live on the islands. Etymologically, Nusa Tenggara means "Southeast Islands" from the words of ''nusa'' which means 'island' from Old Javanese language and ''tenggara'' means 'southeast'. The main Lesser Sunda Islands are, from west to east: Bali, Lombok, Sumbawa, Flores, Sumba, Savu, Rote, Timor, Atauro, Alor archipelago, Barat Daya Islands, and Tanimbar Islands.
