Rabdophaga Strobilina
''Rabdophaga strobilina'' is a gall midge and inquiline of '' Rabdophaga rosaria'' and '' Rabdophaga terminalis''; also gall midges. It was first described by Johann Jacob Bremi-Wolf in 1847. Description ''Rabdophaga rosaria'' forms ''Camellia'' galls (also known as a terminal rosette gall) on willow Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997.

''R. strobilina'' is a close relative of ''R. rosaria'' and the larva of ''strobilina'' live under the modified leaves of the galls made by ''rosaria'' larva. If there are many larva of ''strobilina'', the gall can enlarge and change shape from a rosette, into a 30–40 mm long cone-shaped artichoke. ''R. strobilina'' is also an inquiline of ''Rabdophaga terminalis''. Distribution The insect or gall has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 "'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabdophaga Rosaria
''Rabdophaga rosaria'' is a gall midge which forms ''Camellia'' galls or terminal rosette gall on willow species.Darlington, page 169.Stubbs, page 61. It was first described by Hermann Loew in 1850. Description Willows are extremely susceptible to gall induction and growth manipulation and ''Salix'' is one of the plant genera with the highest known numbers of associated galler species. ''Rabdophaga rosaria'' is probably a group of closely related, unnamed species, possibly each restricted to one species of willow. Galls should be recorded as ''R rosaria'' and the host plant should also be recorded. The gall consists of from thirty to sixty leaves, shortened and crowded together in rosettes on white willow (''S. alba''), crack willow (''S. fragilis''), goat willow (''S. caprea'') and purple willow (''S. purpurea'') willows as well as the eared sallow (''S. aurita'') and grey sallow (''S. cinerea''). The oviposition of this species results in a chemical interaction that halts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabdophaga Terminalis
''Rabdophaga strobilina'' is a gall midge which forms galls on the buds of some species of willow (''Salix'' species). It was first described by Hermann Loew in 1850. Description The gall is green, reddish, later black but never hairy. The leaves of the terminal bud are slightly thickened, sometimes crinkled and curled into an elongate gall, which can be hidden by older leaves. Inside the gall is an elongate cavity with orange or reddish larvae numbering from one to forty. It is uncertain whether white larvae are the young larvae of ''R. terminalis'' or inquilines, '' Macrolabis saliceti'' and/or '' R. strobilina''. The gall has been found on the following species: * '' Salix alba'' – white willow * '' Salix babylonica'' – Babylon willow * '' Salix caesia'' * ''Salix excelsa'' * ''Salix × fragilis'' – crack willow * ''Salix pentandra'' – bay willow * ''Salix purpurea'' – purple willow * ''Salix triandra'' – almond willow * ''Salix viminalis ''Salix viminalis'' ...

Willow
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Johann Jacob Bremi-Wolf
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
