Phyllocoptes Goniothorax
''Phyllocoptes goniothorax'' is a species of mite belonging to the genus ''Phyllocoptes'', which causes galls on the leaves of hawthorns (''Crataegus'' species). It was first described by Alfred Nalepa Alfred Nalepa (19 December 1856, in Werschetz – 11 December 1929, in Baden bei Wien) was an Austrian zoologist specializing in the field of acarology. He studied natural sciences at the University of Vienna, and from 1886 was associated with th ... in 1889. Description There are two types of galls on the leaves of hawthorns. The mites overwinter in a bud or in bark crevices, emerging to attack the new leaves as soon as the buds open, forming tight rolls on the edge of the leaves. The leaf can have many of these yellowish or red galls, which are hairy inside. The mite can also form an erineum on the underside of a leaf with reddish, violet or white hairs with swollen tips. The galls have been found on many different species of hawthorn, including, ''C. coccinoides'', ''C. l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Nalepa
Alfred Nalepa (19 December 1856, in Werschetz – 11 December 1929, in Baden bei Wien) was an Austrian zoologist specializing in the field of acarology. He studied natural sciences at the University of Vienna, and from 1886 was associated with the ''Lehrerbildungsanstalt'' in Linz. In 1892 he returned to Vienna, where he was appointed professor of natural history at the ''Elisabethgymnasium''. He described many species in the field of acarology, and was the taxonomic authority of the gall mite family, Eriophyidae.

Arachnids Of Europe
Arachnida () is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Almost all adult arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 100,000 named species, of which 47,000 are species of spiders. Morphology Almost all adult arachnids have eight legs, unlike adult insects ...

Animals Described In 1889
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms ...

Eriophyidae
Eriophyidae is a family of more than 200 genera of mites, which live as plant parasites, commonly causing galls or other damage to the plant tissues and hence known as gall mites. About 3,600 species have been described, but this is probably less than 10% of the actual number existing in this poorly researched family. They are microscopic mites and are yellow to pinkish white to purplish in color. The mites are worm like, and have only two pairs of legs. Their primary method of population spread is by wind. They affect a wide range of plants, and several are major pest species causing substantial economic damage to crops. Some species, however, are used as biological agents to control weeds and invasive plant species. Notable species Notable species in this family include: *''Abacarus hystrix'', the cereal rust mite *'' Abacarus sacchari'', the sugarcane rust mite *'' Acalitus essigi'', the redberry mite, which affects blackberries *''Aceria chondrillae'', the chondrilla gall ...

Crataegus Sanguinea
''Crataegus sanguinea'' (common names redhaw hawthorn or Siberian hawthorn) is a species of hawthorn that is native to southern Siberia, Mongolia, and the extreme north of China. It is cultivated for its edible red berry-like fruit which actually is a pome. The fruit can be eaten raw or cooked. They can be used to make jam, jelly, and fruit preserves. They are also grown in gardens as ornamental plants. The flowers are small, white in color, and occur in clusters. The flowers give off a carrion smell. The world's largest living individual of this species can be found in Volunteer Park, Seattle, Washington Seattle ( ) is a port, seaport city on the West Coast of the United States. It is the county seat, seat of King County, Washington, King County, Washington (state), Washington. With a 2020 population of 737,015, it is the largest city in bo ....

Crataegus Rhipidophylla
''Crataegus rhipidophylla'' is a species of hawthorn which occurs naturally from southern Scandinavia and the Baltic region to France, the Balkan Peninsula, Turkey, Caucasia, and Ukraine. It is poorly known as a landscape and garden plant, but seems to have potential for those uses. Compared to ''Crataegus monogyna'', ''C. rhipidophylla'' has larger flowers, larger and more colourful fruits, and more decorative foliage. It has a more or less dome-shaped crown, and it is more tolerant of shade than ''C. monogyna''. Description ''Crataegus rhipidophylla'' is a shrub or tree which can grow to tall. Its stout thorns can be up to 1.5 cm long. Leaf blades are dark green, with 2-4 pairs of acute or subacuminate lobes. A helpful characteristic trait for identification is the finely serrated lobe margin. This can help distinguish ''C. rhipidophylla'' from ''C. monogyna'' which has irregularly serrated lobe margins, with more or less coarse teeth. The basal lobes of flowering shoot ...

Crataegus Monogyna
''Crataegus monogyna'', known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world. Names This species is one of several that have been referred to as ''Crataegus oxyacantha'', a name that has been rejected by the botanical community as too ambiguous. In 1793, Medikus published the name ''C. apiifolia'' for a European hawthorn now included in ''C. monogyna,'' but that name is illegitimate under the rules of botanical nomenclature. Other common names include may, mayblossom, maythorn, (as the plant generally flowers in May in the English-speaking parts of Europe) quickthorn, whitethorn, motherdie, and haw. Description The common hawthorn is a shrub or small tree up to about tall, with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear shar ...

Crataegus Laevigata
''Crataegus laevigata'', known as the Midland hawthorn, English hawthorn, woodland hawthorn, or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain (where it is typically found in ancient woodland and old hedgerows) and Spain east to the Czech Republic and Hungary. It is also present in North Africa. The species name is sometimes spelt ''C. levigata'', but the original orthography is ''C. lævigata''. Description It is a large shrub or small tree growing to or rarely to tall, with a dense crown. The leaves are long and broad, with two or three shallow, forward-pointing lobes on each side of the leaf. The hermaphrodite flowers are produced in corymbs of 6 to 12, each flower with five white or pale pink petals and two or sometimes three styles. The flowers are pollinated by insects. The fruit is a dark red pome diameter, slightly broader than long, containing two or three nutlets. It is distinguished from the closely related common ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
