Johan August Wahlberg
Johan August Wahlberg (9 October 1810, in Lackarebäck, Sweden – 6 March 1856, in Lake Ngami, Bechuanaland) was a Swedish naturalist and explorer. Wahlberg started studying chemistry at the University of Uppsala in 1829, and later forestry, agronomy and natural science, graduating from the Swedish Forestry Institute in 1834. In 1832 he joined Professor Carl Henrik Boheman, a famous entomologist, on a collecting trip to Norway. In 1833 and 1834 he travelled in Sweden and Germany on forestry research projects. He joined the Office of Land Survey and was appointed an engineer in 1836, becoming an instructor at the Swedish Land Survey College. He travelled in southern Africa between 1838 and 1856, sending thousands of natural history specimens back to Sweden. He was exploring the Okavango area when he was killed, along the Thamalakane river about 10 km northwest of Maun in today's Botswana, by a wounded elephant. Before his death was known in Sweden, on October 8, 1856 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bush Squeaker
The bush squeaker (''Arthroleptis wahlbergii'') is a species of frog in the family Arthroleptidae. It is found along the coastal areas of eastern South Africa and possibly Mozambique. Habitat Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist shrubland, plantations, rural gardens, urban areas, and heavily degraded former forest, where it is found mostly in leaf-litter and rotting vegetation. Biology and habits The eggs are laid in damp leaf-litter where the young hatch as miniature frogs. The call is a high-pitched squeak, usually emitted during wet weather, which is often mistaken for the calls of crickets. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby .... References * Sasol Field Guide to Frogs of S ...

1810 Births
Year 181 ( CLXXXI) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Burrus (or, less frequently, year 934 ''Ab urbe condita''). The denomination 181 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Imperator Lucius Aurelius Commodus and Lucius Antistius Burrus become Roman Consuls. * The Antonine Wall is overrun by the Picts in Britannia (approximate date).

Gabriel Bibron
Gabriel Bibron (20 October 1805 – 27 March 1848) was a French zoologist and herpetologist. He was born in Paris. The son of an employee of the Museum national d'histoire naturelle, he had a good foundation in natural history and was hired to collect vertebrates in Italy and Sicily. Under the direction of Jean Baptiste Bory de Saint-Vincent (1778–1846), he took part in the Morea expedition to Peloponnese. He classified numerous reptile species with André Marie Constant Duméril (1774–1860), whom he had met in 1832. Duméril was interested mainly in the relations between genera, and he left to Bibron the task of describing the species. Working together they produced the ''Erpétologie Générale'', a comprehensive account of the reptiles, published in ten volumes from 1834 to 1854. Also, Bibron assisted Duméril with teaching duties at the museum and was an instructor at a primary school in Paris. Bibron contracted tuberculosis and retired in 1845 to Saint-A ...

André Marie Constant Duméril
André Marie Constant Duméril (1 January 1774 – 14 August 1860) was a French zoologist. He was professor of anatomy at the Muséum national d'histoire naturelle from 1801 to 1812, when he became professor of herpetology and ichthyology. His son Auguste Duméril was also a zoologist. Life André Marie Constant Duméril was born on 1 January 1774 in Amiens and died on 14 August 1860 in Paris. He became a doctor at a young age, obtaining, at 19 years, the ''prévot'' of anatomy at the medical school of Rouen. In 1800, he left for Paris and collaborated in the drafting of the comparative anatomy lessons of Georges Cuvier. He replaced Cuvier at the Central School of the Panthéon and had, as his colleague, Alexandre Brongniart. In 1801, he gave courses to the medical school of Paris. Under the ''Restauration'', he was elected a member of the Académie des Sciences (French Academy of Sciences) and after 1803 succeeded Lacépède, who was occupied by his political offic ...

Coleoptera
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. 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 insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. 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 ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterocera
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establishe ...

Rhopalocera
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 ...

Trachylepis Wahlbergii
''Trachylepis wahlbergii'', also known commonly as Wahlberg's striped skink, is a species of lizard in the family Scincidae. The species is native to Southern Africa. Taxonomy ''Trachylepis wahlbergii'' has been considered a subspecies of ''Trachylepis striata''. Whether ''T. wahlbergii'' is truly distinct from ''T. striata'' is not fully settled. Geographic range ''T. wahlbergii'' occurs in southern Angola, northern Botswana, northern Namibia, western Mozambique, Zambia, and northern and western Zimbabwe. Etymology The specific name, ''wahlbergi'', is in honour of Swedish Naturalist Johan August Wahlberg.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Trachylepis wahlbergii'', p. 278). Reproduction ''T. wahlbergii'' is viviparous Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproduc ...

''Panaspis wahlbergii'', also known commonly as the Angolan snake-eyed skink, the savannah lidless skink, and Wahlberg's snake-eyed skink, is a species of lizard in the family Scincidae.
