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 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. Inadver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moth
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.

Crambidae
The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae (grass moths) taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects which rest in wing-spread attitudes. In many classifications, the Crambidae have been treated as a subfamily of the Pyralidae or snout-moths. The principal difference is a structure in the tympanal organs called the praecinctorium, which joins two tympanic membranes in the Crambidae, and is absent from the Pyralidae. The latest review by Munroe and Solis, in Kristensen (1999), retains the Crambidae as a full family. The family currently comprises 15 subfamilies with altogether 10,347 species in over 1,000 genera.

Crambus
The genus ''Crambus'' includes around 155 species of moths in the family Crambidae, distributed globally. The adult stages are called crambid snout moths (a name shared with the rest of the family Crambidae, to distinguish them from Pyralidae snout moths), while the larvae of ''Crambus'' and the related genus ''Herpetogramma'' are the sod webworms, which can damage grasses. Life cycle Sod webworms have a bivoltine life cycle with four stages: egg, larva, pupa and imago (adult). They overwinter as larvae in their final or penultimate instar in the thatch or soil. With the coming of warmer weather, the larvae will pupate, and moths will appear in late spring or early summer. The first generation of eggs is laid in June, with larvae appearing in June and lasting until July. Adult moths appear from July until August. Under favorable conditions, a second generation will occur, with the adult stage laying eggs in early October. Egg The eggs of ''Crambus'' species are dry and nonad ...

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design an ...

Corynephorus Canescens
''Corynephorus canescens,'' common name grey hair-grass or gray clubawn grass, is a species of plants in the grass family, native to Europe, the Middle East, and North Africa but widely naturalized in North America. In the United Kingdom it is rare. It can be found at sites such as Wangford Warren and Carr, a Site of Special Scientific Interest in the Breckland area of Suffolk.Wangford Warren and Carr , SSSI citation, .

Festuca Ovina
''Festuca ovina'', sheep's fescue or sheep fescue, is a species of grass. It is sometimes confused with hard fescue (''Festuca trachyphylla''). General description It is a perennial plant sometimes found in acidic ground, and in mountain pasture, throughout Europe (with the exception of some Mediterranean areas) and eastwards across much of Asia; it has also been introduced to North America. It is one of the defining species of the British NVC community CG2, i.e. ''Festuca ovina'' – '' Avenula pratensis'' grassland, one of the calcicolous grassland communities. However, the species has a wide ecological tolerance in the UK, occurring on both basic and acid soils, as well as old mining sites and spoil heaps that are contaminated with heavy metals. Sheep's fescue is a densely tufted perennial grass. Its greyish-green leaves are short and bristle-like. The panicles are both slightly feathery and a bit one-sided. It flowers from May until June, and is wind-pollinated. It has no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' (''s.l.'') are commonly known as whitebeam, rowan (mountain-ash) and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species.

Deschampsia Flexuosa
''Deschampsia flexuosa'', commonly known as wavy hair-grass, is a species of bunchgrass in the grass family widely distributed in Eurasia, Africa, South America, and North America. Description Wavy hair-grass, ''Deschampsia flexuosa'', has wiry leaves and delicate, shaking panicles formed of silvery or purplish-brown flower heads on wavy, hair-like stalks. The leaves are bunched in tight tufts with plants forming a very tussocky, low sward 5 to 20 cm tall before flowering, to 30 cm high. File:Deschampsia flexuosa.jpg, Illustration of ''D. flexuosa'' (including '' D. caespitosa'') File:Avenella flexuosa.jpg, Mature inflorescence Distribution and habitat ''Deschampsia flexuosa'' is found naturally in dry grasslands and on moors and heaths. It is also an important component of the ground flora of birch and oak woodland. The plant has a preference for acidic, free-draining soil, and avoids chalk and limestone areas. It can exist over above sea level. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crambini
Crambinae is a large subfamily of the lepidopteran family Crambidae, the crambid snout moths. It currently includes over 1,800 species worldwide. The larvae are root feeders or stem borers, mostly on grasses. A few species are pests of sod grasses, maize, sugar cane, rice, and other Poaceae. The monophyly of this group is supported by the structure of the tympanal organs and the phallus attached medially to the juxta, as well as genetic analyses. Taxonomists' opinions differ as to the correct placement of the Crambidae, some authorities treating them as a subfamily of the family Pyralidae. If this is done, the present group would be demoted to tribe status, as Crambini.
