Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, it fli ...

Satyrini
The Satyrini is one of the tribes of the subfamily Satyrinae. It includes about 2200 species and is therefore the largest tribe in the subfamily which comprises 2500 species. Distribution Satyrini butterflies have a worldwide distribution, but the distribution pattern differs between subtribes. Some subtribes are almost restricted to a single biogeographic region, such as the Pronophilina, which is found only in Andean cloud forests from Venezuela to Bolivia. Biology The larval food plants of many species in this tribe are grasses, i.e. Poaceae. It is considered that the Satyrini diversified at about the same time as the grasses did, and that the radiation of the tribe is therefore closely related to the evolution of the grasses. In contrast, the tribe has a few genera which show uncommon feeding preferences. Three genera, ''Euptychia'', ''Ragadia'' and ''Acrophtalmia'', feed on Lycopsida, and moreover, some species of ''Euptychia'' have been reported to feed on mosse ...

Ehrharta
''Ehrharta'' is a genus of plants in the grass family.Thunberg, Carl Peter. 1779. Kongliga Vetenskaps Academiens Handlingar 40: 217, pl. 8 Most of the species are native to Africa, with a few from Southeast Asia and from various islands in the Atlantic, Pacific, and Indian Oceans. The genus is also found in Australia, southern Asia, the Mediterranean, and North America. Several including '' Ehrharta longiflora'', '' Ehrharta calycina'' and ''Ehrharta erecta'' are considered invasive weeds. Common names for this genus include veldtgrass.

Caterpillar
Caterpillars ( ) are the larva, larval stage of members of the order Lepidoptera (the insect order comprising butterfly, butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawfly, sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species herbivore, eat plant material (Folivore, often leaves), but not all; some (about 1%) insectivore, eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and Ceratophaga vastella, horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of Agriculture, agricultural Pest (organism), pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricult ...

Vestigial
Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to positive selection pressures when it loses its value in a changing environment. The feature may be selected against more urgently when its function becomes definitively harmful, but if the lack of the feature provides no advantage, and its presence provides no disadvantage, the feature may not be phased out by natural selection and persist across species. Examples of vestigial structures (also called degenerate, atrophied, or rudimentary organs) are the loss of functional wings in island-dwelling birds; the human vomeronasal organ; and the hi ...

Eyespot (mimicry)
An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species. They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; the best-known example is probably the eyespots on a peacock's display feathers. The pattern-forming biological process (morphogenesis) of eyespots in a wide variety of animals is controlled by a small number of genes active in embryonic development, including the genes called Engrailed, Distal-less, Hedgehog, Antennapedia, and the Notch signaling pathway. Artificial eyespots have been show ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Lyell
George Lyell (1866–1951) was an Australian naturalist. He was born on 25 July at Ararat, Victoria. His father, George senior, was a printer born in Scotland; his mother, Jane (née Avery), was born in England. Lyell was educated at Stawell State School. In his late teens, his family moved to South Melbourne, and Lyell worked for seven years, progressing from a position as a junior clerk to becoming the head of a dairy machinery department. In 1890 Lyell accepted a partnership with a different dairy appliance manufacturer, which was also the sole supplier of entomological equipment in Victoria. In 1914, together with Gustavus Athol Waterhouse Gustavus Athol Waterhouse (21 May 1877 – 29 July 1950), was an eminent Australian Entomology, entomologist. Waterhouse was born at Waverley, New South Wales, Waverley in Sydney. His father, Gustavus John, was a Tasmanian born ship owner who al ..., Lyell published ''The Butterflies of Australia'', a comprehensive description of hundre ...

Gustavus Athol Waterhouse
Gustavus Athol Waterhouse (21 May 1877 – 29 July 1950), was an eminent Australian entomologist. Waterhouse was born at Waverley in Sydney. His father, Gustavus John, was a Tasmanian born ship owner who also served as an alderman on the Sydney Municipal Council. His mother, Mary Jane, was also Australian born. Both parents were avid collectors: Gustavus senior collected Pacific Island artefacts; and Mary Jane collected shells. They had five children, Athol being the eldest. He was educated at Waverley Public, then at the Sydney Grammar School, where he was followed by his brothers— Eben Gowrie and Leslie Vickery—and spent lunch hours browsing in the Australian Museum next door. After matriculating from Grammar in 1895, Waterhouse enrolled at the University of Sydney, where he graduated with bachelor's degrees in science (1899) and engineering (1900). His science degree was awarded with first class honours in geology and palaeontology, having studied volcanic dykes in th ...
