Gracillaria Albicapitata
''Gracillaria albicapitata'' is a moth of the family Gracillariidae. It is known from the islands of Hokkaidō and Honshū in Japan and the Russian Far East. The wingspan is 9.8–12.5 mm. The larvae feed on ''Fraxinus lanuginosa'', '' Fraxinus mandshurica'', '' Syringa amurensis'', '' Syringa reticulata'' and ''Syringa vulgaris''. They mine the leaves of their host plant. Young larvae mine directly into the middle layer of the parenchymal tissue of the leaf or leaflet. The mine made by the larvae of the first three 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.

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 ...

Syringa Amurensis
''Syringa reticulata'', the Japanese tree lilac. is a species of flowering plant in the family Oleaceae native to eastern Asia, which is grown as an ornamental in Europe and North America. Description It is a deciduous small tree growing to a height of , rarely to , with a trunk up to , rarely in diameter; it is the largest species of lilac, and the only one that regularly makes a small tree rather than a shrub. The leaves are elliptic-acute, long and broad, with an entire margin, and a roughish texture with slightly impressed veins. The flowers are white or creamy-white, the corolla with a tubular base 0.16–0.24" (4–6 mm) long and a four-lobed apex 0.12–0.24" (3–6 mm) across, and a strong fragrance; they are produced in broad panicles long and broad in early summer.

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'' ...

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 ...

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 ...

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 ...

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"). While there have been some rec ...

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 ...
