Sesia Bembeciformis
''Sesia bembeciformis'', the lunar hornet moth, is a moth of the family Sesiidae. It is found in Europe. The wingspan is 32–42 mm. The length of the forewings is 15–19 mm. ''Sesia bembeciformis'' is hardly distinguishable from its closest congener'' Sesia apiformis''. However, ''apiformis'' has yellow 'epaulettes' on the "shoulders" directly above the wing bases; ''Sesia bembeciformis'' is dark coloured at this point except for the yellow neck ring.''bembeciformis'' is also smaller and has a black head. In general, females are considerably larger than males. It resembles a big hornet (''Vespa crabro'') really well - an instance of mimicry. The moths appear in June, July and August, they are then found resting on the trunks willows . These include sal willow (''Salix caprea''), ash willow (''Salix cinerea'') and ear willow (''Salix aurita ''Salix aurita'', the eared willow, is a species of willow distributed over much of Europe, and occasionally cultivated.

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] |
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. 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 ...

Sesiidae
The Sesiidae or clearwing moths are a diurnal moth family in the order Lepidoptera known for their Batesian mimicry in both appearance and behaviour of various Hymenoptera. The family consists of 165 genera spread over two subfamilies, containing in total 1525 species and 49 subspecies, most of which occur in the tropics, though there are many species in the Holarctic region as well, including over a hundred species known to occur in Europe. Morphology Sesiidae are characterized by their hymenopteriform Batesian mimicry, frequently of identifiable species. Most species of Sesiidae have wings with areas where scales are nearly completely absent, resulting in partial, marked transparency. Forewings are commonly elongated and narrow in the basal half. In many species, the abdomen is elongated, with an anal tuft, and striped or ringed yellow, red or white, sometimes very brightly so. Legs are long, thin and frequently coloured, and in some species the hind-legs are elongated. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buckler W The Larvæ Of The British Butterflies And Moths PlateXXVII
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 ...

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 and anima ...

Sesia Apiformis
The hornet moth or hornet clearwing (''Sesia apiformis'') is a large moth native to Europe and the Middle East and has been introduced to North America. Its protective coloration is an example of Batesian mimicry, as its similarity to a hornet makes it unappealing to predators. The hornet moth has been linked to the large dieback of poplar trees across Europe because its larvae bore into the trunk of the tree before re-emerging as adults. Geographic range ''Sesia apiformis'' is found across mainland Europe, Great Britain, and in parts of the Middle East. It has also recently been introduced to America and Canada. Habitat Adult hornet moths are often found in open habitat such as parks, golf courses, and marshy areas. Females prefer to lay eggs on old or isolated trees, especially trees surrounded by vegetation. Food resources Larvae feed on host trees of several poplar species including '' Populus tremula'' and ''Populus nigra'' as well as '' Salix caprea''. The moth als ...

Vespa Crabro
The European hornet (''Vespa crabro'') is the largest eusocial wasp native to Europe. It is also the only true hornet (genus ''Vespa'') found in North America, having been introduced to the United States and Canada from Europe as early as 1840. Vespines, such as ''V. crabro'', are known for making intricate paper-like nests out of surrounding plant materials and other fibers. Unlike most other vespines, reproductive suppression involves worker policing instead of queen pheromone control, as was previously thought. This species stings in response to being stepped on or grabbed, but generally avoids conflict. It is also defensive of its nest and can be aggressive around food sources. Care should be taken when they are found in these circumstances, as they may sting without warning. European hornets are largely carnivorous and hunt large insects such as beetles, wasps, large moths, dragonflies, and mantises. They also feed on fallen fruit and other sources of sugary food.

Batesian Mimicry
Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates, after his work on butterflies in the rainforests of Brazil. Batesian mimicry is the most commonly known and widely studied of mimicry complexes, such that the word mimicry is often treated as synonymous with Batesian mimicry. There are many other forms however, some very similar in principle, others far separated. It is often contrasted with Müllerian mimicry, a form of mutually beneficial convergence between two or more harmful species. However, because the mimic may have a degree of protection itself, the distinction is not absolute. It can also be contrasted with functionally different forms of mimicry. Perhaps the sharpest contrast here is with aggressive mimicry where a predator or parasite mimics a harmless species, avoiding detection and improving its ...

Salix Caprea
''Salix caprea'', known as goat willow, pussy willow or great sallow, is a common species of willow native to Europe and western and central Asia.Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook 4. . Description It is a deciduous shrub or small tree, reaching a height of , rarely to 13 m. The leaves are 3–12 cm long and from 2–8 cm wide, broader than most other willows. The flowers are soft silky, and silvery 3-7-cm-long catkins are produced in early spring before the new leaves appear; the male and female catkins are on different plants (dioecious). The male catkins mature yellow at pollen release, the female catkins mature pale green. The fruit is a small capsule 5–10 mm long containing numerous minute seeds embedded in fine, cottony hairs. The seeds are very small (about 0.2 mm) with the fine hairs aiding dispersal; they require bare soil to germinate.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins. . The tw ...

Salix Cinerea
''Salix cinerea'' (common sallow, grey sallow, grey willow, grey-leaved sallow, large grey willow, pussy willow, rusty sallow) is a species of willow native to Europe and western Asia.Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4. .Christensen, K. I., & Nielsen, H. (1992). Rust-pil (''Salix cinerea'' subsp. ''oleifolia'') - en overset pil i Danmark og Skandinavien. ''Dansk Dendrologisk Årsskrift'' 10: 5-17. The plant provides a great deal of nectar for pollinators. It was rated in the top 10, with a ranking of second place, for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. Plant It is a deciduous shrub or small tree growing 4–15 metres (13–50 ft) tall. The leaves are spirally arranged, 2–9 cm (1– in) long and 1–3 cm (– in) broad (exceptionally up to 16 cm ...

Salix Aurita
''Salix aurita'', the eared willow, is a species of willow distributed over much of Europe, and occasionally cultivated. It is a shrub to 2.5 m in height, distinguished from the similar but slightly larger ''Salix cinerea'' by its reddish petioles and young twigs. It was named for its persistent kidney-shaped stipule In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). Stipules are considered part of the anatomy of the leaf of a typical flowering plant, although in many speci ...s along the shoots.
