Digitivalva Reticulella
''Digitivalva reticulella'' is a moth of the family Acrolepiidae found in most of Europe, except Ireland, Great Britain, the Netherlands, France, Portugal, Slovenia, much of the Balkan Peninsula, and Lithuania. The wingspan is 11–13 mm. The larvae feed on ''Filago'', '' Gnaphalium luteoalbum'', ''Helichrysum arenarium'', '' Logfia arvensis'', and '' Omalotheca sylvatica''. They mine the leaves of their host plants. Young larvae make a narrow corridor which starts at base of the leaf. The frass Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the ... is deposited in a narrow line. The larva may vacate the mine and start elsewhere. Later mines or mine sections are much wider than the initial corridor. Here, most of the frass is ejected. Older larvae live freely among the flower he ... [...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] |
Filago (plant)
''Filago'' is a genus of plants in the Asteraceae, sunflower family, native from Europe and northern Africa to Mongolia, Nepal, and Macaronesia. They are sometimes called cottonroses or cudweeds. The name cudweed comes from the fact that they were once used to feed cows that had lost the ability to chew the cud. Several species are sometimes treated as members of the genus ''Logfia''. Description They bear woolly, cottony heads of flowers. They have narrow strap-shaped untoothed leaves. The flower heads are small, gathered into dense, stalkless clusters. The fruits have a hairy Pappus (flower structure), pappus, or modified calyx, the part of an individual disk, ray or ligule floret surrounding the base of the corolla, in flower heads of the plant family Asteraceae.

Moths Described In 1796
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.

Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little actual direct contradiction on the practical realities. One glossary from the early twentieth century speaks of "...excrem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Leaf Miner
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta, the mother clade of wasps), and flies (Diptera). Some beetles also exhibit this behavior. Like woodboring beetles, leaf miners are protected from many predators and plant defenses by feeding within the tissues of the leaves, selectively eating only the layers that have the least amount of cellulose. When attacking ''Quercus robur'' (English oak), they also selectively feed on tissues containing lower levels of tannin, a deterrent chemical produced in great abundance by the tree. The pattern of the feeding tunnel and the layer of the leaf being mined is often diagnostic of the insect responsible, sometimes even to species level. The mine often contains frass, or droppings, and the pattern of frass deposition, mine shape, and host plant identity are useful to determi ...

Helichrysum Arenarium
''Helichrysum arenarium'' is also known as dwarf everlast, and as immortelle. Description As a perennial plant, it grows to be an average of 0.3 m tall. The leaves are flat, the lower ones being elliptical in shape, while the upper ones are linear. They are wooly on both sides. The flower heads are arranged in loosely, a cross between umbel and panicle. They are 3 to 4 mm wide of bright golden yellow florets.

Gnaphalium Luteoalbum
''Helichrysum luteoalbum'', the Jersey cudweed, is a species of flowering plant in the family Asteraceae. Description It is an erect herbaceous biennial up to tall, branching from the base. Leaves are oblanceolate to lanceolate and covered in hairs like that of the edelweiss. The leaves can survive frozen over in winter. Flowers are cream, yellow, white, or pink. Seeds have a pappus which lets them float over long distances. Taxonomy This species was first published by Carl Linnaeus in his 1753 ''Species plantarum'', under the name ''Gnaphalium luteo-album'' (the orthography was later changed to omit the hyphen). In 1829, Ludwig Reichenbach transferred it to '' Helichrysum'', but this name was not taken up, and the species was retained in '' Gnaphalium'' until 1981, when Olive Mary Hilliard and Brian Laurence Burtt transferred it into '' Pseudognaphalium''. In 2004, an investigation into the phylogenetic relationships of ''Helichrysum'' and related genera found this speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
