Criorhina Berberina
''Criorhina berberina'' is a species of hoverfly. It is found in the Palaearctic from Fennoscandia South to Iberia and Italy. Ireland eastwards through Europe into Turkey and European Russia . ''C. berberina'' is a bumblebee mimic. The body has uniformly long dense pubescence, obscuring the ground-colour. There are two forms one with the pubescence more or less extensively blackish (typical ''berberina''), one in which it is entirely yellow or tawny (''berberina'' var. ''oxyacanthae'' Meigen). ''Criorhina'' differ from other bumblebee mimics - ''Mallota'', '' Arctophila'', ''Pocota'' and ''Brachypalpus'' by the form of their antennae: the first segments are thin and form a stalk, the third segment is shorter than it is wide. In ''Criorhina'', the face projects downwards, in contrast to ''Pocota'' and ''Brachypalpus''. Larvae of ''C. berberina'' are associated with rotting deciduous wood. The larva is figured by Hartley (1961) and Rotheray (1993) Adults are arboreal an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Arctophila (fly)
''Arctophila'' is a subgenus of hoverflies, in the genus ''Sericomyia'' from the family Syrphidae, in the order Diptera Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing".

Eristalinae
Eristalinae (or Milesiinae) are one of the four subfamilies of the fly family Syrphidae, or hoverflies. A well-known species included in this subfamily is the dronefly, ''Eristalis tenax''. Species in this subfamily are often misclassified as bees instead of flies due to their exceptional Mimicry, especially to resemble Honeybees (family Apidae). The best strategy for proper identification is to look at their eyes and wings and compare with fly morphology, to determine membership of family Syrphidae and/or of order Hymenoptera. Taxonomy This subfamily consists of the following tribes: * Brachyopini * Callicerini * Cerioidini * Eristalini * Sericomyiini * Eumerini * Milesiini * Pipizini * Rhingiini * Spheginobacchini * Volucellini gallery Brachyopa daeckei.jpg, ''Brachyopa daeckei'' actual size Sphiximorpha subsessilis, Parc de Woluwé, Brussels (34851582946).jpg, ''Sphiximorpha subsessilis'' Namaste!

Diptera Of Europe
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioindicator
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollutants in the ecosystem and about how long a problem may have been present, which physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative information on the quality of the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional information about the amount and intensity of the exposure. A biological indicator is also the name given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Records Centre
The Biological Records Centre (BRC) established in 1964, is a national focus in the UK for terrestrial and fresh water species recording. The term "biological records centre" is also used in the context of local centres, now frequently referred to as "local environmental records centres" (LERCs). History The Biological Records Centre (BRC) was set up in 1964 by the Nature Conservancy (UK) at its recently opened Monks Wood Experimental Station near Huntingdon. BRC developed from the Atlas of the British Flora project of the Botanical Society of the British Isles (BSBI) to map the distribution of British (and Irish) flowering plants, which had established basic principles for biological recording in the UK. The former BSBI project leader, Franklyn Perring, established BRC with the project's original data and data processing equipment. Function As part of the UK Centre for Ecology & Hydrology (UKCEH), BRC provides a focus for the collation, management, dissemination and interpret ...

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 ...

Johann Wilhelm Meigen
Johann Wilhelm Meigen (3 May 1764 – 11 July 1845) was a German entomologist famous for his pioneering work on Diptera. Life Early years Meigen was born in Solingen, the fifth of eight children of Johann Clemens Meigen and Sibylla Margaretha Bick. His parents, though not poor, were not wealthy either. They ran a small shop in Solingen. His paternal grandparents, however, owned an estate and hamlet with twenty houses. Adding to the rental income, Meigen's grandfather was a farmer and a guild mastercutler in Solingen. Two years after Meigen was born, his grandparents died and his parents moved to the family estate. This was already heavily indebted by the Seven Years' War, then bad crops and rash speculations forced the sale of the farm and the family moved back to Solingen. Meigen attended the town school but only for a short time. He had learned to read and write on his grandfather's estate and he read widely at home as well as taking an interest in natural history.

Mimicry
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect a species from predators, making it an anti-predator adaptation. Mimicry evolves if a receiver (such as a predator) perceives the similarity between a mimic (the organism that has a resemblance) and a model (the organism it resembles) and as a result changes its behaviour in a way that provides a selective advantage to the mimic. The resemblances that evolve in mimicry can be visual, acoustic, chemical, tactile, or electric, or combinations of these sensory modalities. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a form of mutualism; or mimicry can be to the detriment of one, making it parasitic or competitive. The evolutionary convergence between groups is driven by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
