Ash Bud Moth
''Prays fraxinella'', the ash bud moth, is a moth of the family Plutellidae. It is found in Europe. The wingspan is 14–18 mm. The head is white or greyish ochreous. Forewings are white or greyish-ochreous; some blackish dorsal strigulae; a triangular blackish blotch, lighter or mixed with whitish on costa, extending along costa from near base to 2/3; some irregular blackish marks towards termen; sometimes the whole wing is unicolorous dark fuscous. Hind wings are rather dark grey. The larva is greenish, marbled with red -brown above; dorsal line deep green; head pale brown, dark-spotted; 2 with two black spots.Meyrick, E., 1895 ''A Handbook of British Lepidoptera'' MacMillan, Londopdf Keys and description Adults are on wing from May to June and again in August in two generations depending on the location. The larvae feed on '' Fraxinus excelsior'' and ''Fraxinus ornus''. They mine the leaves of their host plant. The mine consists of an irregular small corridor with disp ...

Clas Bjerkander
Clas Bjerkander (23 September 1735, Skara – 1 August 1795) was a Swedish meteorologist, botanist, and entomologist. A Lutheran pastor, Bjerkander studied at the University of Uppsala. With Anders Dahl he wrote ''Svenska Topographiska Sällskapet i Skara'' ("Schwedische topographische Gesellschaft zu Skara") and, as sole author several short scientific papers on Microlepidoptera. Taxa named for him include *'' Pyralis bjerkandriana'' (Mehlmotte) *'' Bjerkandera'' P. Karst In 1778, Bjerkander was elected a member of the Royal Swedish Academy of Sciences.

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] |
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 Moths And Butterflies Of Great Britain And Ireland
''The Moths and Butterflies of Great Britain and Ireland'' (abbreviated to ''MBGBI'' or ''MOGBI'') is a multi-volume reference work on the Lepidoptera of the British Isles. The original publisher of this series was Curwen Books who published volumes 1 and 9. In 1983 Harley Books took over publishing the series. The earlier volumes were reprinted. From 1 April 2008 following the retirement of Annette and Basil Harley, Apollo Books acquired Harley Books. It was decided, that Apollo Books would continue and conclude the series with volume 5 on Tortricidae, volume 6 on Pyralidae and Pterophoridae, and volume 8 on Geometridae. At the same time they took over the remaining stock of the previous seven volumes of the series. From 1 January 2013, Apollo Books announced that all Harley Books titles and the majority of the Apollo Books titles, have been taken over by the Dutch publisher Brill Publishers. The change was necessary to ensure that the book series can continue to be published i ... [...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 determi ...

Fraxinus Ornus
''Fraxinus'' (), 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 subtropical species are evergreen. The genus is widespread across much of Europe, Asia, and North America. The leaves are opposite (rarely in whorls of three), and mostly 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. Some ''Fraxinus'' species are 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, ashes can cause a considerable litter problem with their seeds.

Fraxinus Excelsior
''Fraxinus excelsior'', known as the ash, or European ash or common ash to distinguish it from other types of ash, is a flowering plant species in the olive family Oleaceae. It is native throughout mainland Europe east to the Caucasus and Alborz mountains, and Britain and Ireland, the latter determining its western boundary. The northernmost location is in the Trondheimsfjord region of Norway.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Den virtuella floran''Fraxinus excelsior'' distribution/ref> The species is widely cultivated and reportedly naturalised in New Zealand and in scattered locales in the United States and Canada. Description It is a large deciduous tree growing to (exceptionally to ) tall with a trunk up to (exceptionally to ) diameter, with a tall, narrow crown. The bark is smooth and pale grey on young trees, becoming thick and vertically fissured on old trees. The shoots are stout, greenish-grey, with jet-black buds (which distinguish ...
