Agrotis Trux
''Agrotis trux'', the crescent dart, is a moth of the family Noctuidae. The species was first described by Jacob Hübner in 1824. It has a circum-Mediterranean distribution and is found along the coasts of France, Ireland, England, southern Europe, Algeria, Syria, Iraq, Iran, southern Russia and the Arabian Peninsula. In Africa, it is found as far south as South Africa. Description The wingspan is 35–42 mm. Forewing ochreous grey, dappled and striated, and often, especially in the females, suffused with dark fuscous; claviform stigma black-edged; reniform large, filled in with black; orbicular small, round, with a pale ring; fringe rufous; hindwing dull whitish, with fuscous terminal suffusion, broader in female; or with a curved row of dark dashes on veins and no suffusion; a variable species, occurring throughout southern Europe, in Algeria, the Canaries, southern Russia and Asia Minor; — in ab. ''olivina'' Stgr. the forewing is smooth olive grey, with no or little ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Hübner
Jacob Hübner (20 June 1761 – 13 September 1826, in Augsburg) was a German entomologist. He was the author of ''Sammlung Europäischer Schmetterlinge'' (1796–1805), a founding work of entomology. Scientific career Hübner was the author of ''Sammlung Europäischer Schmetterlinge'' (1796–1805), a founding work of entomology. He was one of the first specialists to work on the European Lepidoptera. He described many new species, for example ''Sesia bembeciformis'' and ''Euchloe tagis'', many of them common. He also described many new genus, genera. He was a designer and engraver and from 1786 he worked for three years as a designer and engraver at a cotton factory in Ukraine. There he collected butterflies and moths including descriptions and illustrations of some in ''Beiträge zur Geschichte der Schmetterlinge'' (1786–1790) along with other new species from the countryside around his home in Augsburg. Hübner's masterwork "Tentamen" was intended as a discussion document. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forewing
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the dragonflies and lacewings). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects. Physically, some insects move their flight muscles directly, others indirectly. In insects with direct flight, the wing muscles directly attach to the wing base, so that a small downward movement of the wing base lifts the wing itself upward. Those i ...

Agrotis
''Agrotis'' is a genus of moths of the family Noctuidae. The genus was erected by Ferdinand Ochsenheimer in 1816. A number of the species of this genus are extinct. Description The proboscis is well developed. Palpi obliquely porrect (extending forward), where the second joint evenly scaled and third joint prominent. Thorax and abdomen without tufts. Abdomen somewhat flattened. Tibia very strongly spined. Forewings with non-crenulate outer margin. Hindwings with veins 3 and 4 from cell. Ecology Many of the species are of great importance as cutworms, major agricultural pests whose larvae hide by day and emerge at night to feed. The name ''cutworm'' refers to the habit of the larvae, of cutting down and partly eating garden and crop plants, especially seedlings. Not all cutworms are in the genus ''Agrotis'', though it may well be the genus that includes the largest number of cutworm species, and the most agriculturally important cutworm species.

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Polygonum
''Polygonum'' is a genus of about 130 species of flowering plant in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass (though the common names may refer more broadly to plants from Polygonaceae). In the Middle English glossary of herbs ''Alphita'' ( 1400–1425), it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat (''Fagopyrum esculentum'') has sometimes been included in the genus as ''Polygonum fagopyrum''. Former genera such as ''Polygonella'' have been subsumed into ''Polygonum''; other genera have been split off. The genus primarily grows in northern temperate regions. The species are very diverse, ranging from prostrate herbaceous annual plants to erect herbaceous perennial plants. ''Polygonum'' species are occasionally eaten by humans, and are used as food plants by the larvae of some Lepidoptera species – see list. Most species are considered weeds i ...

Taraxacum
''Taraxacum'' () is a large genus of flowering plants in the family Asteraceae, which consists of species commonly known as dandelions. The scientific and hobby study of the genus is known as taraxacology. The genus is native to Eurasia and North America, but the two most commonplace species worldwide, '' T. officinale'' (the common dandelion) and '' T. erythrospermum'' (the red-seeded dandelion), were introduced from Europe into North America, where they now propagate as wildflowers. Both species are edible in their entirety. The common name ''dandelion'' ( , from French , meaning 'lion's tooth') is also given to specific members of the genus. Like other members of the family Asteraceae, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a ''floret''. In part due to their abundance, along with being a generalist species, dandelions are one of the most vital early spring nectar sources for a wide host ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts o ...

Buckler W The Larvæ Of The British Butterflies And Moths PlateLXXI
A buckler (French ''bouclier'' 'shield', from Old French ''bocle, boucle'' 'boss') is a small shield, up to 45 cm (up to 18 in) in diameter, gripped in the fist with a central handle behind the boss. While being used in Europe since antiquity, it became more common as a companion weapon in hand-to-hand combat during the Medieval and Renaissance periods. Its size made it poor protection against missile weapons (e.g., arrows) but useful in deflecting the blow of an opponent's weapons, binding his arms, hindering his movements, or punching him. MS I.33, considered the earliest extant armed-combat manual, (around 1300) contains an early description of a system of combat with buckler and sword. Typology According to the typology of Schmidt, there are three main types of buckler regarding their shape: *Type I: round *Type II: rectangular or trapezoid *Type III: oval or teardrop-shaped These types are combined with the cross sections: *Type a: flat *Type b: concave *Type ...
