Oncopsis flavicollis is a species of leafhoppers belonging to the family Cicadellidae subfamily Eurymelinae.
Oncopsis flavicollis can reach a length of about 4.5–5.5 millimetres (0.18–0.22 in). It is a sexual dimorph species. Males show dark markings on the face with round spots. Females are very variable, with different colour forms. Usually they are bright-yellow on the upper part of the face, on the forebody and on the base of the wings, while the remaining part of the wings are chestnut brown. Adult can be found in forest environment from May to September. These leafhoppers feeds on birch ( Betula pendula and Betula pubescens ). [1] [2] [3]
This species can be found in most of Europe, in the Near East, in North Africa and in the eastern Palearctic realm. [4] [5]
A birch is a thin-leaved deciduous hardwood tree of the genus Betula, in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech-oak family Fagaceae. The genus Betula contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are a typically rather short-lived pioneer species widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates.
Betula pendula, commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe, it is only found at higher altitudes. Its range extends into Siberia, China, and southwest Asia in the mountains of northern Turkey, the Caucasus, and northern Iran. It has been introduced into North America, where it is known as the European white birch or weeping birch and is considered invasive in some states in the United States and parts of Canada. The tree can also be found in more temperate regions of Australia.
Betula pubescens, commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch, but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch.
Betula nigra, the black birch, river birch or water birch, is a species of birch native to the Eastern United States from New Hampshire west to southern Minnesota, and south to northern Florida and west to Texas. It is one of the few heat-tolerant birches in a family of mostly cold-weather trees which do not thrive in USDA Zone 6 and up. B. nigra commonly occurs in floodplains and swamps.
Betula papyrifera is a short-lived species of birch native to northern North America. Paper birch is named for the tree's thin white bark, which often peels in paper like layers from the trunk. Paper birch is often one of the first species to colonize a burned area within the northern latitudes, and is an important species for moose browsing. The wood is often used for pulpwood and firewood.
Betula alleghaniensis, the yellow birch, golden birch, or swamp birch, is a large tree and an important lumber species of birch native to northeastern North America. Its vernacular names refer to the golden color of the tree's bark. In the past the species name was Betula lutea.
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.
Brochosomes are intricately structured microscopic granules secreted by leafhoppers and typically found on their body surface and, more rarely, eggs. Brochosomes were first described in 1952 with the aid of an electron microscope. Brochosomes are hydrophobic and help keep the insect cuticle clean. These particles have also been found in samples of air and can easily contaminate foreign objects, which explains erroneous reports of brochosomes on other insects.
The beet leafhopper, also sometimes known as Neoaliturus tenellus, is a species of leafhopper which belongs to the family Cicadellidae in the order Hemiptera.
Aphrophora alni, the European alder spittle bug, is a species belonging to the family Aphrophoridae.
Cicadella viridis, the green leafhopper, is a species belonging to the subfamily Cicadellinae of the family Cicadellidae.
Empoasca decipiens is a species of leafhopper belonging to the family Cicadellidae subfamily Typhlocybinae. The adults reach 3–4 millimetres (0.12–0.16 in) of length and a are homogenously green with whitish markings on its pronotum and vertex. E. decipiens is commonly referred to as the “green leafhopper” because of its colouration. The absence of clear stripes along the forewings can easily distinguish it from the similar leafhopper species E. vitis, but distinguishing it from other leafhoppers with the same colouration requires examination under a microscope. It is present in most of Europe, in the eastern Palearctic realm, in North Africa, in the Near East, and in the Afrotropical realm. Both nymphs and adults of this small insect are considered to be a very destructive pests on field crops, vegetables and greenhouse plants.
Ledra aurita or the eared leafhopper is a species of bug in the family Cicadellidae. It is the only species of the subfamily Ledrinae that lives in Europe, including the British Isles.
Japananus hyalinus, the Japanese maple leafhopper, is a species of leafhopper of the subfamily Deltocephalinae and tribe Opsiini. Believed to be native to eastern Asia, it has been carried with the trade in cultivated maples and is now widely found in Europe, North America and Australia.
Eurymeloides bicincta, commonly known as the two-lined gum-treehopper, is a leafhopper in the family Cicadellidae. It is the type species of the genus Eurymeloides. It is a sap-sucking insect and is found on gum-trees in its native southeastern Australia.
Empoasca fabae belongs to family Cicadellidae and genus Empoasca within order Hemiptera. They are more commonly referred to as the potato leafhopper. In North America they are a serious agricultural pest. Every year millions of dollars are lost from reduced crop yields and on pest management. Crops that are impacted the most are potatoes, clover, beans, apples and alfalfa.
Erythroneura infuscata, commonly known as Leafhopper is a species of leafhopper in the family Cicadellidae.
Amrasca biguttula, commonly known as the cotton jassid, is a subspecies of leafhopper belonging to the subfamily Typhlocybinae of family Cicadellidae. It is a pest of cotton, okra, and other crops in southern Asia.
Anoscopus albifrons is a species of insect in the family Cicadellidae. It was first described by Carl Linnaeus in 1758, in the 10th Edition of his Systema Naturae. It is found throughout Europe, the Azores, and parts of the United States and Canada. It inhabits grassy areas and forbs.
Erasmoneura vulnerata is a species of leafhopper native to North America. The species was found to be in Europe in 2004 where it causes significant economic damage to grapevine yards. E. vulnerata is commonly found on wild and cultivated grapes from both continents. Its Latin name translates to "wounded Erasmoneura" from its original description.
