Gracillaria Ussuriella
''Gracillaria ussuriella'' is a moth of the family Gracillariidae. It is known from the islands of Hokkaidō, Honshū and Kyūshū in Japan and the Russian Far East. The wingspan is 9.8–12 mm. The larvae feed on '' Fraxinus'' species, including ''Fraxinus americana'', ''Fraxinus chinensis'', '' Fraxinus mandshurica'' and ''Fraxinus pennsylvanica''. They mine the leaves of their host plant. The mine made by the larva of the first three instars is large, lower-parenchymal Parenchyma () is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology it is the name for the tissue that fills the interior of flatworms. Etymology The term ''parenchyma'' is New Latin from the word ..., and tentiformed. The leaf roll made by the larva of the late instars is conical, or often cigarette-formed when many larvae inhabit a single leaflet. The cocoons are ordinarily formed inside the leaf roll. They are shining white and spindle-shaped. The ... [...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.

Fraxinus Americana
''Fraxinus americana'', the white ash or American ash, is a species of '' ash tree'' native to eastern and central North America. The species is native to mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas. Isolated populations have also been found in western Texas Texas (, ; Spanish language, Spanish: ''Texas'', ''Tejas'') is a state in the South Central United States, South Central region of the United States. At 268,596 square miles (695,662 km2), and with more than 29.1 million residents in 2 ..., Wyoming, and Colorado, and the species is reportedly naturalized in Hawaii. There are an estimated 8 billion ash trees in the United States – the majority being the white ash trees and the Fraxinus pennsylvanica, green ash trees. Characteristics The name white ash derives from the glaucous undersides of the leaves. It is similar in appearance to the green ash, making identification difficult. ...

Gracillariinae
Gracillariinae are a subfamily of moths which was described by Henry Tibbats Stainton in 1854. The subfamilies of Gracillariidae differ by the adult moth resting posture.(Davis and Robinson, 1999) Most Gracillariinae rest with the front of the body steeply raised; Lithocolletinae and Phyllocnistinae rest with the body parallel to the surface; in Lithocolletinae often with the head lowered. Genera Gracillariidae phylogeny has been revised in 2017(Kawahara et al. 2017) and the Acrocercopinae subfamily is contains 25 genera (59 genera were affected to other subfamilies): *'' Africephala'' Vári, 1986 *'' Apistoneura'' Vári, 1961 *'' Aristaea'' Meyrick, 1907 *'' Artifodina'' Kumata, 1985 *''Aspilapteryx'' Spuler, 1910 **=''Sabulopteryx'' Triberti, 1985 *'' Callicercops'' Vári, 1961 *'' Caloptilia'' Hübner, 1825 **=''Poeciloptilia'' Hübner, 1825 **=''Ornix'' Collar, 1832 **=''Ornix'' Treitschke, 1833 **=''Coriscium'' Zeler, 1839 **=''Calliptilia'' Agassiz, 1847 **=''Timodora'' ...

Parenchymal
Parenchyma () is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology it is the name for the tissue that fills the interior of flatworms. Etymology The term ''parenchyma'' is New Latin from the word παρέγχυμα ''parenchyma'' meaning 'visceral flesh', and from παρεγχεῖν ''parenchyma'' meaning 'to pour in' from παρα- ''para-'' 'beside' + ἐν ''en-'' 'in' + χεῖν ''chyma'' 'to pour'. Originally, Erasistratus and other anatomists used it to refer to certain human tissues. Later, it was also applied to plant tissues by Nehemiah Grew. Structure The parenchyma is the ''functional'' parts of an organ, or of a structure such as a tumour in the body. This is in contrast to the stroma, which refers to the ''structural'' tissue of organs or of structures, namely, the connective tissues. Brain The brain parenchyma refers to the functional tissue in the brain that is made up of the two types of brain cell, neurons and ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

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 ...

Fraxinus Pennsylvanica
''Fraxinus pennsylvanica'', the green ash or red ash, is a species of ash native to eastern and central North America, from Nova Scotia west to southeastern Alberta and eastern Colorado, south to northern Florida, and southwest to Oklahoma and eastern Texas. It has spread and become naturalized in much of the western United States and also in Europe from Spain to Russia. Other names more rarely used include downy ash, swamp ash and water ash. Description ''Fraxinus pennsylvanica'' is a medium-sized deciduous tree reaching (rarely to ) tall with a trunk up to in diameter. The bark is smooth and gray on young trees, becoming thick and fissured with age. The winter buds are reddish-brown, with a velvety texture. The leaves are long, oppositely arranged, pinnately compound with seven to nine (occasionally five or eleven) leaflets, these (rarely ) long and broad, with serrated margins and short but distinct, downy petiolules a few millimeters long. They are green both above ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraxinus Mandshurica
''Fraxinus mandshurica'', the Manchurian ash, is a species of ''Fraxinus'' native to northeastern Asia in northern China (Gansu, Hebei, Heilongjiang, Henan, Hubei, Jilin, Liaoning, Shaanxi, Shanxi), Korea, Japan and southeastern Russia (Sakhalin Island). It is a medium-sized to large deciduous tree reaching 30 m tall, with a trunk up to 50 cm in diameter. The leaves are 25–40 cm long, pinnate compound, with 7–13 leaflets, the leaflets 5–20 cm long and 2–5 cm broad, subsessile on the leaf rachis, and with a serrated margin. They turn to a golden-yellow in early autumn, and the tree is usually early to change color. The flowers are produced in early spring, before the new leaves, in compact panicles; they are inconspicuous with no petals, and are wind-pollinated. The fruit is a samara comprising a single seed 1–2 cm long with an elongated apical wing 2.5–4 cm long and 5–7 mm broad. It is closely related to ''Fraxinus nigra'' (Black ...

Fraxinus
''Fraxinus'' (), common name, commonly called ash, is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45–65 species of usually medium to large trees, mostly deciduous, though a number of Subtropics, subtropical species are evergreen. The genus is widespread across much of Europe, Asia, and North America. The leaf, leaves are opposite leaves, opposite (rarely in Whorl (botany), whorls of three), and mostly pinnate, pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara (fruit), samara. Some ''Fraxinus'' species are Dioecy, dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness ; if grown as an ornamental and both sexes are present, ...

Gracillariidae
Gracillariidae is an important family of insects in the order Lepidoptera and the principal family of leaf miners that includes several economic, horticultural or recently invasive pest species such as the horse-chestnut leaf miner, ''Cameraria ohridella''. Taxonomy and systematics There are 98 described genera of Gracillariidae (see below). A complete checklist is available of all currently recognised species. There are many undescribed species in the tropics but there is also an online catalogue of Afrotropical described speci the South African fauna is quite well known. Although Japanese and Russian authors have recognised additional subfamilies, there are three currently recognised subfamilies, Phyllocnistinae of which is likely to be basal. In this subfamily, the primitive genus ''Prophyllocnistis'' from Chile feeds on the plant genus '' Drimys'' (Winteraceae), and has leaf mines structurally similar in structure to fossils (see "Fossils").

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 ...
