Psephenidae
Water-penny beetles are a family (the Psephenidae) of 272 species (in 35 genera) of aquatic beetles found on all continents except Antarctica, in both tropical and temperate areas. The young, which live in water, resemble tiny pennies. The larvae feed – usually nocturnally – on algae on rock surfaces. The presence of water-penny larvae in a stream can be used as a test for the quality of the water, as they are pollution-sensitive. They cannot live in habitats where rocks acquire a thick layer of algae, fungi, or inorganic sediment. Therefore, their presence along with other diverse phyla signifies good-quality water. They are around 6 to 10 millimeters in length. A water-penny larva's shell is oval-shaped to almost circular and is commonly a copper color, which explains the name, 'water-penny'. Water-pennies obtain oxygen through their membrane and through feathery gills located at the base of the abdomen. They are typically found in riffles in streams with a moderate to ...

Aquatic Beetle
A water beetle is a generalized name for any beetle that is adapted to living in water at any point in its life cycle. Most water beetles can only live in fresh water, with a few marine species that live in the intertidal zone or littoral zone. There are approximately 2000 species of true water beetles native to lands throughout the world. Many water beetles carry an air bubble, called the elytra cavity, underneath their abdomens, which provides an air supply, and prevents water from getting into the spiracles. Others have the surface of their exoskeleton modified to form a plastron, or "physical gill", which permits direct gas exchange with the water. Some families of water beetles have fringed hind legs adapted for swimming, but most do not. Most families of water beetles have larvae that are also aquatic; many have aquatic larvae and terrestrial adults. Diet Water beetles can be either herbivores, predators, or scavengers. Herbivorous beetles eat only aquatic vegetation, such ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found within the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within northern Myanmar. The s ...

Jean Théodore Lacordaire
Théodore Lacordaire or Jean Théodore Lacordaire (1 February 1801 – 18 July 1870) was a Belgian entomologist of French extraction. In spite of his obvious interest in natural history, his family sent him to Le Havre to study "le droit", or the law. In 1824, he embarked for Buenos Aires where he became a commercial salesman. He traveled widely in South America using every opportunity to carry out many observations on local fauna. Georges Cuvier suggested he come to Paris in 1830. There he met Pierre André Latreille, Jean Victoire Audouin, and André Marie Constant Duméril and took part in the foundation of the Société Entomologique de France. He went to Guyana at the end of 1830 to collect natural history specimens, returning to France in 1832. In 1835, he became professor of zoology at the University of Liège where he succeeded Henri-Maurice Gaède (1795–1834). In 1837, he became also professor of comparative anatomy. He occupied himself actively with the collection ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
