Rabdophaga Salicis
''Rabdophaga salicis'' is a gall midge which forms galls on sallows (''Salix'' species). It was first described by Franz von Paula Schrank in 1803. Description The gall is a smooth, globular or spindle-shaped swelling, usually on a twig or stem and contains larvae or pupae in up to fifty separate chambers. The galls are usually 10–40 mm long and about 10 mm wide and the larvae feed on the pith inside the gall. The gall, does not contain frass, and occasionally occurs on the petiole, midrib, or side veins of a leaf. The larvae are pale orange or reddish, over-winter in the gall and pupate in the spring. In Britain the gall is widespread and common and is found on creeping willow (''Salix repens ''Salix repens'', the creeping willow, is a small, shrubby species of willow in the family Salicaceae, growing up to 1.5metres in height.

Franz Von Paula Schrank
Franz von Paula Schrank (21 August 1747, in Vornbach – 22 December 1835) was a German priest, botanist and entomologist. He was ordained as a priest in Vienna in 1784, gaining his doctorate in theology two years later. In 1786 he was named chair of mathematics and physics at the lyceum in Amberg, and in 1784 became a professor of botany and zoology at the University of Ingolstadt (later removed to Landshut). at Catholic Encyclopedia Schrank was the first director of the botanical gardens in from 1809 to 1832. Schrank was the first author to use the name '' |
Salix Daphnoides
''Salix daphnoides'', the European violet willow, is a species of plant in the family Salicaceae. It can grow as a large shrub or small tree, normally reaching a height of , but can grow up to tall. Description It has a rounded crown with spreading branches with smooth, grey bark. The twigs are dark red/brown in colour, hairless and somewhat shiny. It has large buds, either hairless or with stiff, erect hairs. The leaves are oblong to narrow/obovate, normally between 7 and 12 cm long and 2 to 3 cm in width. They are hairy at first, but soon become glabrous, being a dark shiny green on their upper surfaces, and glaucous on their undersides. The catkins appear in February–March. Distribution and habitat Salix daphnoides occurs scattered across central Europe between the Baltic states and Piedmont, and from the Balkans to eastern France. It is native in the Alps, Pyrenees and the Carpathians, but has been naturalised by cultivation across a much wider area. It occurs ...

Insects Described In 1803
Insects (from Latin ') are pancrustacean Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes and one pair of antenna (biology), 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 taxon, 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 Natural environment, environments, although only a small number of species reside in the oceans, which are dominated by ...

Diptera Of Asia
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] |

Rabdophaga Saliciperda
''Rabdophaga saliciperda'' is a species of gall midges which forms galls on willows (''Salix'' species). It was first described by Léon Jean Marie Dufour Léon Jean Marie (or Jean-Marie Léon) Dufour (10 April 1780, Saint-Sever – 18 April 1865) was a French medical doctor and naturalist. Between 1799 and 1806 he studied medicine in Paris then returned to Saint-Sever in the Landes. He participate ... in 1841.

Larvae are in individual chambers and are described as yellowish-orange, or greenish yellow to white or reddish depending on the authority. Larvae prepare emergence windows before pupating.

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] |
