Chalcosoma Caucasus
''Chalcosoma chiron'' (often called the Caucasus beetle) is a species of beetle in the family Scarabaeidae. This species can be found from Malaysia south into Indonesia (Sumatra, Java, Malay Peninsula, Indochina) and Thailand in East region ( Chanthaburi province, Sa Kaeo province). It was formerly known as ''Chalcosoma caucasus'', a name which is a junior synonym and not valid. Description ''Chalcosoma chiron'' males can reach a length of , while females grow to . Caucasus beetles are the largest of the genus ''Chalcosoma'' and one of Asia's largest beetles. They have a striking sexual dimorphism. The male has specialised enormous, curved horns on its head and thorax that it can use to fight with other males to gain mating rights with females. A female is significantly smaller. The elytra of the females have a velvety texture, as they are covered by tiny hairs. Caucasus beetles differ from Atlas beetles (for which they are often mistaken) in that they have a small tooth on t ... [...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 . Jean-Baptiste-François Gigot d'Orcy later employed Olivier who was then able to travel to England and Holland meeting Thomas Martyn in London. In 1789 and 1790 he published the first two volumes of the ''Histoire naturelle des Coléoptères'' for Gigot d'Orcy, and simultaneously, thanks to Daubenton's recommendation, collaborated in the ''Dictionnaire de l'Histoire naturelle des Insectes, Papillons, Crustacés'' and 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 collecti ...

Beetles Of Malaysia
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ...

Dynastinae
Dynastinae or rhinoceros beetles are a subfamily of the scarabaeidae, scarab beetle family (biology), family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1,500 species and 225 genera of rhinoceros beetles are known. Many rhinoceros beetles are well known for their unique shapes and large sizes. Some famous species are, for example, the Atlas beetle (''Chalcosoma atlas''), common rhinoceros beetle (''Xylotrupes ulysses''), elephant beetle (''Megasoma elephas''), European rhinoceros beetle (''Oryctes nasicornis''), Hercules beetle (''Dynastes hercules''), Japanese rhinoceros beetle or ''kabutomushi'' (''Allomyrina dichotoma''), ox beetle (''Strategus aloeus'') and the Eastern Hercules beetle (''Dynastes tityus''). Description The Dynastinae are among the largest of beetles, reaching more than in length, but are completely harmless to humans because they cannot ...

West Malaysia
Peninsular Malaysia, historically known as Malaya and also known as West Malaysia or the Malaysian Peninsula, is the western part of Malaysia that comprises the southern part of the Malay Peninsula on Mainland Southeast Asia and the nearby islands. Its area totals approximately , which is nearly 40% of the total area of the country; the other 60% is in East Malaysia on the island of Borneo. It shares a land border with Thailand to the north and a maritime border with Singapore to the south. Across the Strait of Malacca to the west lies the island of Sumatra, and across the South China Sea to the east lie the Natuna Islands of Indonesia. At its southern tip, across the Strait of Johor, lies the island country of Singapore. Most of Peninsular Malaysia's interior is forested, mountainous and rural; the majority of Malaysia's population and economy are concentrated on the coastal western half, which is where the country's prominent urban areas are located.

Vietnam
Vietnam, officially the Socialist Republic of Vietnam (SRV), is a country at the eastern edge of mainland Southeast Asia, with an area of about and a population of over 100 million, making it the world's List of countries and dependencies by population, fifteenth-most populous country. One of two communist states in Southeast Asia, Vietnam shares land borders with China to the north, and Laos and Cambodia to the west. It shares Maritime boundary, maritime borders with Thailand through the Gulf of Thailand, and the Philippines, Indonesia, and Malaysia through the South China Sea. Its capital is Hanoi and its largest city is Ho Chi Minh City. Vietnam was inhabited by the Paleolithic age, with states established in the first millennium BC on the Red River Delta in modern-day northern Vietnam. Before the Han dynasty's invasion, Vietnam was marked by a vibrant mix of religion, culture, and social norms. The Han dynasty annexed Northern and Central Vietnam, which were subs ...

Langkawi
Langkawi, officially known as Langkawi, the Jewel of Kedah (), is a duty-free island and an archipelago of 99 islands (plus five small islands visible only at low tide in the Strait of Malacca) located some 30 km off the coast of northwestern Malaysia and a few kilometres south of Ko Tarutao, adjacent to the Thailand, Thai border. Politically, it is an administrative list of districts in Malaysia, district of Kedah, with Kuah as its largest town. Langkawi was developed as a tourist destination in the 1980s, and Pantai Cenang is the island's most popular beach and tourist area. Etymology The name ''Langkawi'' is thought to have existed by the early 15th century, although in the 16th century the island of Langkawi was also marked on maps variously as Langa, Langka, Lansura, and Langapura.

Elytra
An elytron (; ; : elytra, ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripipho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
