Proconiini
The name sharpshooter is used to refer to any of various genera and species of large leafhoppers in the tribe Proconiini of the family leafhopper, Cicadellidae. As with all cicadellids, they have piercing-sucking mouthparts and closely spaced rows of fine spines on their hind legs. The nymphs feed by inserting their needle-like mouthparts into the xylem of the small stems on the plant where the eggs were deposited; the adults have wings and are highly mobile, and most feed on a variety of different plant species. Both nymphs and adults filter a huge volume of dilute liquid through their Digestion#Digestive system, digestive system to extract the trace nutrients, and much of the water and carbohydrates are squirted forcibly away from the body in a fine stream of droplets, thus earning them their common name. This group includes a few species which are plant pests, the most serious of which is ''Homalodisca vitripennis'' (the "Glassy-winged sharpshooter"). A microbial plant parasit ...

Homalodisca Vitripennis
The glassy-winged sharpshooter (''Homalodisca vitripennis'', formerly known as ''H. coagulata'') is a large leafhopper (family Cicadellidae), similar to other species of sharpshooter. Description These sharpshooters are about in length. Their color is dark brown to black with black-and-yellow undersides, with yellow eyes, and the upper parts of the head and back are speckled with ivory or yellowish spots. The wings are transparent with reddish veins.APHIS. 2002Glassy-winged Sharpshooter and Pierce's Disease in California They have piercing, sucking mouthparts and rows of fine spines on their hind legs. Distribution It is native to North America (northeastern Mexico), but it was accidentally introduced into Southern California in the early 1990s, probably with ornamental or agricultural stock. There it has become an agricultural pest especially to viticulture. Glassy-winged sharpshooters usually lay a mass of eggs on the underside of leaves, and they cover them with powdery w ...

Leafhopper
A leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species. They belong to a lineage traditionally treated as infraorder Cicadomorpha in the suborder Auchenorrhyncha, but as the latter taxon is probably not monophyletic, many modern au ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Xylem
Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word ''xylem'' is derived from the Ancient Greek word (''xylon''), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout a plant. The term was introduced by Carl Nägeli in 1858. Structure The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called ''vessels''. Xylem also contains two other type of cells: parenchyma and fibers. Xylem can be found: * in vascular bundles, present in non-woody plants and non-woody parts of woody plants * in secondary xylem, laid down by a meristem called the vascular cambium in woody plants * as part of a stelar arrangement n ...
