Orchid Mantis
''Hymenopus coronatus'' is a mantis from the tropical forests of Southeast Asia. It is known by various common names including walking flower mantis and (pink) orchid mantis. It is one of several species known as flower mantises from their resemblance and behaviour. They are known to grab their prey with blinding speed. Description This species mimics parts of the Orchidaceae, orchid flower. The four walking legs resemble flower petals, and the toothed front pair is used as in other mantises for grasping prey. ''H. coronatus'' shows some of the most pronounced size sexual dimorphism of any species of mantis; males can be less than half the size of females. The female predatory selection is the likely driving force behind the development of the extreme sexual size dimorphism. Prior to development of its camouflage, the female mantis implements ambush predation to allow it to hunt larger pollinating insects. An example of this ambush predation is the orchid mantis's ability to ambu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guillaume-Antoine Olivier
Guillaume-Antoine Olivier (; 19 January 1756, Les Arcs near Toulon – 1 October 1814, Lyon) was a French entomologist and naturalist. Life Olivier studied medicine in Montpellier, where he became good friends with Pierre Marie Auguste Broussonet. With Jean Guillaume Bruguière and Jean-Baptiste Lamarck, he collaborated in the creation of ''Journal d'Histoire Naturelle'' (1792). Afterwards, he served as a naturalist on a 6-year scientific journey that took him to Asia Minor, Persia, Egypt, Cyprus and Corfu. He returned to France in 1798 with a large collection of natural history specimens from his travels. Later, he was associated with the '' École nationale vétérinaire d'Alfort'', where in 1811, he was appointed professor of zoology. Olivier was a close friend of Johan Christian Fabricius and a patron of Pierre André Latreille. Although primarily an entomologist, Olivier also worked in the scientific field of herpetology, describing several new species of Asian lizards. ...

Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiang Mai Province
Chiang Mai ( th, เชียงใหม่, ; nod, , ) is the largest Province ('' changwat'') of Thailand. It lies in upper northern Thailand and has a population of 1.78 million people.

Exuviae
In biology, exuviae are the remains of an exoskeleton and related structures that are left after ecdysozoans (including insects, crustaceans and arachnids) have moulted. The exuviae of an animal can be important to biologists as they can often be used to identify the species of the animal and even its sex. As studying insects, crustaceans, or arachnids directly is not always possible, and because exuviae can be collected fairly easily, they can play an important part in helping to determine some general aspects of a species' overall life cycle such as distribution, sex ratio, production, and proof of breeding in a habitat. Exuviae have been suggested as a "gold standard" for insect monitoring. For instance, when monitoring dragonfly populations the presence of exuviae of a species demonstrates that the species has completed its full life cycle from egg to adult in a habitat. However, it has also been suggested that the fact that exuviae can be hard to find could lead to an unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Colours Of Animals
''The Colours of Animals'' is a zoology book written in 1890 by Sir Edward Bagnall Poulton (1856–1943). It was the first substantial textbook to argue the case for Darwinian selection applying to all aspects of animal coloration. The book also pioneered the concept of frequency-dependent selection and introduced the term "aposematism". The book begins with a brief account of the physical causes of animal coloration. The second chapter gives an overview of the book, describing the various uses of colour in terms of the advantages it can bring through natural selection. The next seven chapters describe camouflage, both in predators and in prey. Methods of camouflage covered include background matching, resemblance to specific objects such as bird droppings, self-decoration with materials from the environment, and the seasonal colour change of arctic animals. Two chapters cover warning colours, including both Batesian mimicry, where the mimic is edible, and Mullerian mimic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Bagnall Poulton
Sir Edward Bagnall Poulton, FRS HFRSE FLS (27 January 1856 – 20 November 1943) was a British evolutionary biologist, a lifelong advocate of natural selection through a period in which many scientists such as Reginald Punnett doubted its importance. He invented the term sympatric for evolution of species in the same place, and in his book ''The Colours of Animals'' (1890) was the first to recognise frequency-dependent selection. Poulton is also remembered for his pioneering work on animal coloration. He is credited with inventing the term aposematism for warning coloration, as well as for his experiments on 'protective coloration' (camouflage). Poulton became Hope Professor of Zoology at the University of Oxford in 1893. Life Edward Poulton was born in Reading, Berkshire on 27 January 1856 the son of the architect William Ford Poulton and his wife, Georgina Sabrina Bagnall. He was educated at Oakley House School in Reading. Between 1873 and 1876, Poulton studied at Je ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

James Wood-Mason
James Wood-Mason (December 1846 – 6 May 1893) was an English zoologist. He was the director of the Indian Museum at Calcutta, after John Anderson. He collected marine animals and lepidoptera, but is best known for his work on two other groups of insects, phasmids (stick insects) and mantises (praying mantises). The genus ''Woodmasonia'' Brunner, 1907, and at least ten species of phasmids, are named after him.Bragg, 2008.

Darwinism (book)
''Darwinism: An Exposition of the Theory of Natural Selection with Some of Its Applications'' is an 1889 book on evolution by Alfred Russel Wallace, the co-discoverer of evolution by natural selection together with Charles Darwin. This was a book Wallace wrote as a defensive response to the scientific critics of natural selection. Of all Wallace's books, it is cited by scholarly publications the most. Synopsis In ''Darwinism'' fifteen chapters, Alfred Russel Wallace sets out his understanding of the theory of evolution by natural selection. He begins by defining "species", discussing creationism, opinion before Charles Darwin, and Darwin's theory. He then describes the Malthusian struggle for existence, given the ability of organisms to reproduce in a world of finite resources. He explains the importance of variability within species, giving examples. He describes variation in domesticated animals and cultivated plants, and the process of artificial selection by breeders. ...

Alfred Russel Wallace
Alfred Russel Wallace (8 January 1823 – 7 November 1913) was a British natural history, naturalist, explorer, geographer, anthropologist, biologist and illustrator. He is best known for independently conceiving the theory of evolution through natural selection. His 1858 paper on the subject was published that year On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection, alongside extracts from Charles Darwin's earlier writings on the topic. It spurred Darwin to set aside the Natural Selection (manuscript), "big species book" he was drafting, and quickly write an Abstract (summary), abstract of it, published in 1859 as ''On the Origin of Species''. Wallace did extensive fieldwork, first in the Amazon River basin. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western port ...
