''Digitivalva arnicella'' is a moth of the family Acrolepiidae. It is found in Norway, Sweden, the Netherlands, Belgium, Denmark, Germany, France, Switzerland, Austria, Italy, Hungary, Slovakia, the Czech Republic, Romania, Poland and Lithuania. The wingspan is . Adults are on wing in May. The larvae feed on '' Arnica montana''. They mine the leaves of their host plant. The mine starts as a light green, narrow, sometimes branching corridor. It widens considerably later. 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 an irregular, broad central line. Larvae often leave their mine and start anew in another leave. Pupation takes place in a separate, lower-surface mine. The larvae are white. They can be found from autumn to May. References ...

Carl Von Heyden
Carl Heinrich Georg(es) von Heyden (20 January 1793 Frankfurt – 7 July 1866) was a German senator and entomologist. He collected insects in all orders but was especially interested in Coleoptera, Microlepidoptera, Hymenoptera, Diptera and fossil insects. His collections are divided between the German Entomological Institute and the Senckenberg Museum. He studied forestry under Johann Matthäus Bechstein at the Dreißigacker Forest Academy near Meiningen, then continued his education at the University of Heidelberg. With his son, Lukas von Heyden, he conducted studies of fossil insects found in lignite. In addition to his entomological research, he performed investigations of reptile specimens collected by Eduard Rüppell in North Africa North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, and it is sometimes defined as stretching from the Atlantic shores of Mauritan ...

Slovakia
Slovakia (; sk, Slovensko ), officially the Slovak Republic ( sk, Slovenská republika, links=no ), is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the southwest, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about , with a population of over 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice. The Slavs arrived in the territory of present-day Slovakia in the fifth and sixth centuries. In the seventh century, they played a significant role in the creation of Samo's Empire. In the ninth century, they established the Principality of Nitra, which was later conquered by the Principality of Moravia to establish Great Moravia. In the 10th century, after the dissolution of Great Moravia, the territory was integrated into the Principality of Hungary, which then became the Kingdom of Hungary in 1000. In 124 ...

Moths Of Europe
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 es ...

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 "...excreme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 de ...

Arnica Montana
''Arnica montana'', also known as wolf's bane, leopard's bane, mountain tobacco and mountain arnica, is a moderately toxic European flowering plant in the daisy family Asteraceae. It is noted for its large yellow flower head. The names "wolf's bane" and "leopard's bane" are also used for another plant, aconitum, which is extremely poisonous. ''Arnica montana'' is used as an herbal medicine for analgesic and anti-inflammatory purposes, but there is insufficient high-quality clinical evidence for such effects, and it is toxic when taken internally or applied to injured skin. Description ''Arnica montana'' is a flowering plant about tall aromatic fragrant, herbaceous perennial. Its basal green ovate leaves with rounded tips are bright coloured and level to the ground. In addition, they are somewhat downy on their upper surface, veined and aggregated in rosettes. By contrast, the upper leaves are opposed, spear-shaped and smaller which is an exception within the Asteraceae ... [...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 an ...
