Johann Christoph Friedrich Klug
Johann Christoph Friedrich Klug (5 May 1775, in Berlin – 3 February 1856, in Berlin), was a German entomologist. He described the butterflies and some other insects of Upper Egypt and Arabia in Christian Gottfried Ehrenberg and Wilhelm Friedrich Hemprich's ''Symbolæ Physicæ'' (Berlin, 1829–1845). He was professor of medicine and entomology in the University of Berlin (known in the present day as the Humboldt University of Berlin) where he curated the insect collections from 1810 to 1856. At the same time he directed the Botanic Garden in Berlin which contains his collections. Klug worked mainly on Hymenoptera and Coleoptera. The plant genus '' Klugia'' (now called '' Rhynchoglossum'', Family Gesneriaceae) was named in his honour as well as the butterflies ''Geitoneura klugii'' and '' Heliophisma klugii''. In 1855, he was elected a foreign member of the Royal Swedish Academy of Sciences. Works (Partial List) * Die Blattwespen nach ihren Gattungen und Arten zusammengestellt. ...

Tenthredinidae
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis. The family has no easily seen diagnostic features, though the combination of five to nine antennal flagellomeres plus a clear separation of the first abdominal tergum from the metapleuron can reliably separate them. These sawflies are often black or brown, and 3 to 20 mm long. Like other sawflies, they lack the slender "wasp-waist", or petiole, between the thorax and abdomen, characteristic of many hymenopterans. The mesosoma and the metasoma are instead broadly joined. The Tenthredinidae are also often somewhat dorsoventrally flattened, which will distinguish them ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anthriscus Sylvestris
''Anthriscus sylvestris'', known as cow parsley, wild chervil, wild beaked parsley, Queen Anne's lace or keck, is a herbaceous biennial or short-lived perennial plant in the family Apiaceae (Umbelliferae), genus ''Anthriscus''. It is also sometimes called mother-die (especially in the UK), a name that is also applied to the common hawthorn. It is native to Europe, western Asia and northwestern Africa. It is related to other diverse members of Apiaceae, such as parsley, carrot, hemlock and hogweed. It is often confused with ''Daucus carota'', another member of the Apiaceae also known as "Queen Anne's lace" or "wild carrot". Description Cow parsley is an upright herbaceous (non-woody) perennial, growing to tall. The stems are hollow, striate (striped with parallel, longitudinal lines), furrowed, and green in colour with flushes of purple, with a diameter up to . It has tiny hairs on the stem, rachis, and leaf stalks which are difficult to see but can easily be detected by t ...

Epilobium Hirsutum
''Epilobium hirsutum'' is a flowering plant belonging to the willowherb genus ''Epilobium'' in the family Onagraceae. It is commonly known as the great willowherb, great hairy willowherb or hairy willowherb. Local names include codlins-and-cream, apple-pie and cherry-pie. Description It is a tall, perennial plant, reaching up to 2 metres in height. The robust stems are profusely hairy with soft spreading hairs. The hairy leaves are 2–12 cm long and 0.5–3.5 cm wide. They are long and thin and are widest below the middle. They have sharply toothed edges and no stalk. The large flowers have four notched petals. These are purple-pink and are usually 10–16 mm long. The stigma is white and has four lobes. The sepals are green. Distribution The native range of the species includes North Africa, most of Europe up to southern Sweden, and parts of Asia. It is absent from much of Scandinavia and north-west Scotland. It has been introduced to North America and Austra ...

Chamerion Angustifolium
''Chamaenerion angustifolium'' is a Perennial plant, perennial Herbaceous plant, herbaceous flowering plant in the willowherb family Onagraceae. It is known in North America as fireweed, in some parts of Canada as great willowherb, in Britain and Ireland as rosebay willowherb. In the United Kingdom it is also known as bombweed, as a result of its rapid appearance on city bomb sites during the Blitz of World War II; the plant is also traditionally known as Anthony the Great, Saint Anthony's laurel. It is also known by the Synonym (taxonomy), synonyms ''Chamerion angustifolium'' and ''Epilobium angustifolium''. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests. Description The reddish stems of this herbaceous perennial are usually simple, erect, smooth, high with scattered alternate leaves. The leaves are spirally arranged, entire, narrowly lanceolate, and pinnately veined, the secondary leaf veins anastomosing, joining to ...

Pteridium Aquilinum
''Pteridium aquilinum'' (bracken, brake or common bracken), also known as eagle fern, is a species of fern occurring in temperate and subtropical regions in both hemispheres. Originally native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution. Etymology Common bracken was first described as ''Pteris aquilina'' by Carl Linnaeus, in Volume 2 of his ''Species Plantarum'' in 1753. The origin of the specific epithet derived from the Latin ''aquila'' "eagle". In the reprint of the ''Flora Suecica'' in 1755, Linnaeus explains that the name refers to the image of an eagle seen in the transverse section of the root. In spite of this, the opinion has been forwarded that the name pertains to the shape of the mature fronds appearing akin to an eagle's wing. However, medieval scholars, including Erasmus, thought the pattern of the fibres seen in a transverse section of the stipe resembled a double-headed eagle or oak tree. Ta ...

Salix
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nearctic Realm
The Nearctic realm is one of the eight biogeographic realms constituting the Earth's land surface. The Nearctic realm covers most of North America, including Greenland, Central Florida, and the highlands of Mexico. The parts of North America that are not in the Nearctic realm are Eastern Mexico, Southern Florida, coastal Central Florida, Central America, and the Caribbean islands, which, together with South America, are part of the Neotropical realm. Major ecological regions The World Wildlife Fund (WWF) divides the Nearctic into four bioregions, defined as "geographic clusters of ecoregions that may span several habitat types, but have strong biogeographic affinities, particularly at taxonomic levels higher than the species level (genus, family)." Canadian Shield The Canadian Shield bioregion extends across the northern portion of the continent, from the Aleutian Islands to Newfoundland. It includes the Nearctic's Arctic Tundra and Boreal forest ecoregions. In terms of flo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Insects Described In 1814
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
