Vasates Quadripedes
''Vasates quadripedes'', the maple bladder-gall mite, is an eriophyid mite in the genus ''Vasates'', which causes galls on the leaves of silver maple (''Acer saccharinum ''Acer saccharinum'', commonly known as silver maple, creek maple, silverleaf maple, soft maple, large maple, water maple, swamp maple, or white maple, is a species of maple native to the eastern and central United States and southeastern Ca ...''), red maple ('' A. rubrum''), and sugar maple ('' A. saccharum''). The gall is rounded, sometimes elongate, and has a short, thin neck. Typically, galls are in diameter, and may be numerous on the upper surfaces of leaves. They have an opening in the lower surface. At first they are yellowish-green or bright red, later they become dark red and black. In Britain, the mite affects introduced silver maple. The species is relatively new to Britain, being first recorded in London in 2002. References Eriophyidae Animals described in 1869 Arachnids ...

Sugar Maple
''Acer saccharum'', the sugar maple, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is native to the hardwood forests of eastern Canada and eastern United States. Sugar maple is best known for being the primary source of maple syrup and for its brightly colored fall foliage. It may also be known as "rock maple", "sugar tree", "birds-eye maple", "sweet maple", "curly maple", or "hard maple", particularly when referring to the wood. Description ''Acer saccharum'' is a deciduous tree normally reaching heights of , and exceptionally up to . A 10-year-old tree is typically about tall. As with most trees, forest-grown sugar maples form a much taller trunk and narrower canopy than open-growth ones. The leaves are deciduous, up to long and wide, palmate, with five lobes and borne in opposite pairs. The basal lobes are relatively small, while the upper lobes are larger and deeply notched. In contrast with the angular notching of the silver maple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Shimer
Henry Shimer (September 21, 1828 – July 28, 1895) was a naturalist and physician in Mount Carroll, Illinois. He was also a teacher at the Mount Carroll Seminary, which later became Shimer College; he was the husband of the seminary's founder, Frances Shimer. Biography Early life Shimer was born on September 21, 1828, in West Vincent Township, Chester County, Pennsylvania. He worked as a stone mason in his youth and took up teaching at the age of 18. In March 1854, Shimer left Pennsylvania and traveled west to Mount Carroll, Illinois after a failed love affair. He may have done work on the construction or expansion of the Mount Carroll Seminary, for which the owners were unable to pay him. Marriage On December 22, 1857, Shimer and Frances Ann Wood, the co-principal of the Mount Carroll Seminary, were married. Their union was widely reputed to be a marriage of convenience. Vocations Shimer subsequently left for Chicago to study medicine. He graduated from the Chicag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 gal ...

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external Tissue (biology), tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology. In human pathology, a gall is a raised sore on the skin, usually caused by chafing or rubbing. Causes of plant galls Insects and mites Insect galls are the highly distinctive plant structures formed by some Herbivore, herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Gal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acer Saccharinum
''Acer saccharinum'', commonly known as silver maple, creek maple, silverleaf maple, soft maple, large maple, water maple, swamp maple, or white maple, is a species of maple native to the eastern and central United States and southeastern Canada. It is one of the most common trees in the United States. Although the silver maple's Latin name is similar, it should not be confused with ''Acer saccharum'', the sugar maple. Some of the common names are also applied to other maples, especially '' Acer rubrum''. Description The silver maple tree is a relatively fast-growing deciduous tree, commonly reaching a height of , exceptionally . Its spread will generally be wide. A 10-year-old sapling will stand about tall. It is often found along waterways and in wetlands, leading to the colloquial name "water maple". It is a highly adaptable tree, although it has higher sunlight requirements than other maple trees. The leaves are simple and palmately veined, long and broad, wit ...

Acer Rubrum
''Acer rubrum'', the red maple, also known as swamp maple, water maple, or soft maple, is one of the most common and widespread deciduous trees of eastern and central North America. The U.S. Forest Service recognizes it as the most abundant native tree in eastern North America. The red maple ranges from southeastern Manitoba around the Lake of the Woods on the border with Ontario and Minnesota, east to Newfoundland, south to Florida, and southwest to East Texas. Many of its features, especially its leaves, are quite variable in form. At maturity, it often attains a height around . Its flowers, petioles, twigs, and seeds are all red to varying degrees. Among these features, however, it is best known for its brilliant deep scarlet foliage in autumn. Over most of its range, red maple is adaptable to a very wide range of site conditions, perhaps more so than any other tree in eastern North America. It can be found growing in swamps, on poor, dry soils, and almost anywhere in betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Animals Described In 1869
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 a ...
