Elachista Subnigrella
''Elachista subnigrella'' is a moth of the family Elachistidae found in Europe. Description The wingspan is . The head is dark grey, face lighter. Forewings blackish-grey, light-sprinkled, in female darker except on basal area ; a slender indistinct fascia before middle, somewhat indented or interrupted on fold, in male sometimes almost obsolete, a small indistinct tornal spot, and costal spot somewhat beyond it whitish, in female whiter and more distinct. Hindwings are rather dark grey.The larva is pale yellow ; head pale brown. Hindwings are grey. Biology Adults are on wing from April to May. The larvae feed on ''Avena'', ''Avenula pubescens'', ''Bromus erectus'', ''Calamagrostis epigejos'', ''Dactylis glomerata'', ''Festuca'' and ''Holcus mollis''. They leaf miner, mine the leaves of their host plant. Larvae can be found from April to May and again in July. Distribution It is found from Scandinavia and the Baltic States to the Pyrenees and Italy and from Ireland to Romania. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John William Douglas
John William Douglas (15 November 1814 – 28 July 1905) was an English entomologist, chiefly interested in microlepidoptera. He was popularly known as "Jolly" Douglas for his ability to produce jocular doggerel in the style of Longfellow's ''Hiawatha''. Biography John William Douglas was born 1814 in Putney. His father came from Edinburgh. In a schoolboy prank gone wrong, a fellow student dropped a match into his pocket which contained crackers resulting in serious injury to his leg. Two years largely confined in bed forced him to take up botanical drawing and when he was able to walk again took up work at Kew as a botanical illustrator. He became interested in insects whilst working at Kew Gardens and published many papers and books on entomology. His most important work was ''The Natural History of the Tineina'' with the German Philipp Christoph Zeller, Englishman Henry Tibbats Stainton and a Swiss, Heinrich Frey. The ''Natural History of the Tineina'' appeared in English, F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltic States
The Baltic states, et, Balti riigid or the Baltic countries is a geopolitical term, which currently is used to group three countries: Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone, and the OECD. The three sovereign states on the eastern coast of the Baltic Sea are sometimes referred to as the "Baltic nations", less often and in historical circumstances also as the "Baltic republics", the "Baltic lands", or simply the Baltics. All three Baltic countries are classified as high-income economies by the World Bank and maintain a very high Human Development Index. The three governments engage in intergovernmental and parliamentary cooperation. There is also frequent cooperation in foreign and security policy, defence, energy, and transportation. The term "Baltic states" ("countries", "nations", or similar) cannot be used unambiguously in the context of cultural areas, national identity, or language. While the majority ...

Moths Described In 1853
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 ...

Leaf Miners
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 ...

Elachista
''Elachista'' is a genus of gelechioid moths described by Georg Friedrich Treitschke in 1833. It is the type genus of the grass-miner moth family (Elachistidae). This family is sometimes (in particular in older sources) circumscribed very loosely, including for example the Agonoxenidae and Ethmiidae which seem to be quite distinct among the Gelechioidea, as well as other lineages which are widely held to be closer to ''Oecophora'' than to ''Elachista'' and are thus placed in the concealer moth family Oecophoridae here. These grass-miners are very small moths with the "feathery" hindwings characteristic of their family. They are essentially found worldwide, except in very cold places and on some oceanic islands; as usual for Gelechioidea, they are most common in the Palearctic however. They usually have at least one, sometimes as many as three light bands running from leading to trailing edge of their forewing uppersides. Some species, however, have upper forewings that are mo ...
