Rabdophaga Marginemtorquens
''Rabdophaga marginemtorquens'' is a gall midge which forms gall Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to be ...s on willows (''Salix'' species) and is found in Europe. It was described by Johann Jacob Bremi-Wolf in 1847. Appearance of the gall The eggs are laid between the bud scales in the spring. The gall is a short or long downward, hairless, roll containing one or several yellowish-red or orange larvae. The galls are of varying lengths, often run together and often have orange, red or white patches. There are two or three generations in a year, with the summer generations pupating in the gall and the autumn generation pupating in the soil. It is found on white willow ( ''S. alba''), goat willow ( ''S. caprea''), grey willow ( ''S. cinerea''), violet willow ( ''S. daphn ...

Johann Jacob Bremi-Wolf
Johann Jacob Bremi-Wolf (25 May 1791, Dübendorf – 27 February 1857, Zürich) was a Swiss entomologist and ''Kunsthandwerker'' (artist wood turner) in Zürich.Guyet, E. V., 1974 ''Vom Naturalienkabinett der Naturforschenden Gesellschaft in Zürich zum Zoologischen Museum der Universität Vierteljahrsschrift der Naturforschenden Gesellschaft in Zürich, Zürich'' 119, S. 379, pp. 376-381, Schr.verz. Bremi was born in Dübendorf, Switzerland to a pastor Johann Heinrich Bremi. He became deaf due to typhus fever at the age of 11 which made him shift from a clergy career to a trade in wood work with lathes. He however took an interest in insects and began to collect them and read about science. He married Magdalena Barbara Wolf in 1818 and they had two children. He corresponded with J.J. Siegfried of Zurich, Oswald Heer, Johannes Jacob Hegetschweiler and Friedrich Schulthess. He noted in poems that his deafness allowed him to focus on work but at some times he expressed a wish for ...

Insects Described In 1847
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ...

Rabdophaga
''Rabdophaga'' is genus of flies in the family of gall midges Cecidomyiidae. There are 105 species distributed through Africa, Asia, Europe and North America. Most species of ''Rabdophaga'' gall willows (''Salix'' sp.); one exception is ''R. giraudiana'' which galls the stems of poplars ( ''Populus'' sp.).

Inquiline
In zoology, an inquiline (from Latin ''inquilinus'', "lodger" or "tenant") is an animal that lives commensally in the nest, burrow, or dwelling place of an animal of another species. For example, some organisms such as insects may live in the homes of gophers or the garages of humans and feed on debris, fungi, roots, etc. The most widely distributed types of inquiline are those found in association with the nests of social insects, especially ants and termites – a single colony may support dozens of different inquiline species. The distinctions between parasites, social parasites, and inquilines are subtle, and many species may fulfill the criteria for more than one of these, as inquilines do exhibit many of the same characteristics as parasites. However, parasites are specifically ''not'' inquilines, because by definition they have a deleterious effect on the host species, while inquilines have not been confirmed to do so. In the specific case of termites, the term "'' ...

Rabdophaga Roskami
''Rabdophaga roskami'' is a gall midge which may form gall Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to be ...s on common ossier (''Salix viminalis'') or, the larva live in the galls formed by ''R. marginemtorquens''. It was first described by H Stelter in 1989. Appearance of the gall There is some uncertainty as to whether ''R. roskami'' makes galls on '' Salix viminalis'' or is an inquiline with the larva living in the galls of ''R. marginemtorquens''. The possible gall is a short, downward, hairless, roll containing a cream or light-reddish larva on ''S. viminalis''. Larvae of ''R. marginemtorquens'' are yellowish-red or orange. Distribution Recorded from Germany and possibly from Great Britain. References {{Taxonbar, from=Q13623290 roskami Diptera of Europe Gall-indu ...

Armenia
Armenia (), , group=pron officially the Republic of Armenia,, is a landlocked country in the Armenian Highlands of Western Asia.The UNbr>classification of world regions places Armenia in Western Asia; the CIA World Factbook , , and ''Oxford Reference Online'' also place Armenia in Asia. It is a part of the Caucasus region; and is bordered by Turkey to the west, Georgia to the north, the Lachin corridor (under a Russian peacekeeping force) and Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south. Yerevan is the capital, largest city and the financial center. Armenia is a unitary, multi-party, democratic nation-state with an ancient cultural heritage. The first Armenian state of Urartu was established in 860 BC, and by the 6th century BC it was replaced by the Satrapy of Armenia. The Kingdom of Armenia reached its height under Tigranes the Great in the 1st century BC and in the year 301 became the first state in the world to adopt ...

Salix Purpurea
''Salix purpurea'', the purple willow purpleosier willow or purple osier, is a species of willow native to most of Europe and western Asia north to the British Isles, Poland, and the Baltic States.Flora Europaea''Salix purpurea''/ref>Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4. .Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . It is a deciduous shrub growing to 1–3 m (rarely to 5 m) tall, with purple-brown to yellow-brown shoots, turning pale grey on old stems. The leaves are 2–8 cm (rarely to 12 cm) long and 0.3–1 cm (rarely 2 cm) wide; they are dark green above, glaucous green below, and unusually for a willow, are often arranged in opposite pairs rather than alternate. The flowers are small catkins 1.5-4.5 cm long, produced in early spring; they are often purple or red in colour, whence the name of the species (other willows mostly have whitish, yellow or green catkins). It is r ...

Cecidomyiidae
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only in length; many are less than long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa. More than 6,650 species and 830 genera are described worldwide, though this is certainly an underestimate of the actual diversity of this family. A DNA barcoding study published in 2016 estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a staggering global count of over 1 million cecidomyiid species that have yet ...

Salix Elaeagnos
''Salix eleagnos'' the bitter willow, olive willow, hoary willow, rosemary willow, or elaeagnus willow, is a species of flowering plant in the family Salicaceae, native to central and southern Europe and south west Asia. Growing to tall by broad, it is an erect bushy deciduous shrub with narrow grey-green leaves up to long, which turn yellow in autumn (fall). The green catkins, long, appear with the leaves in spring, male catkins having yellow anthers. Like all willows, the species is dioecious. The specific epithet ''eleagnos'' is frequently spelt ''elaeagnos'' ( Elaeagnus, silverberry or oleaster), though the original spelling has been accepted as a correct Greek form. ''Salix eleagnos'' subsp. ''angustifolia'' has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK grow ...
