Parasyrphus Nigritarsis
''Parasyrphus nigritarsis'' is a species of hoverfly, from the family Syrphidae, in the order Diptera. It is known from northern Europe and North America, and has been considered to be a rare species in parts of its range. Adults visit flowers as a source of nutrition, and females lay their eggs on clutches of eggs of leaf beetles (family Chrysomelidae). When the ''Parasyrphus'' larvae hatch, they first consume leaf beetle eggs and then consume immature beetles until they reach the pupal stage. This species is related to hoverflies that prey on aphids as larvae, and has been investigated in studies of chemical ecology and food web ecology. Distribution and habitat In Eurasia, ''P. nigritarsus'' occurs in the Nordic countries, south to Belgium, Germany, Switzerland and northern Spain, Ireland east through Central Europe into Russia and on to the Russian Far East and Japan. In North America, it occurs from Alaska to Quebec and south to Washington and Idaho. Thus, ''P. nigritarsus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Wilhelm Zetterstedt
Johan Wilhelm Zetterstedt (20 May 1785 – 23 December 1874) was a Swedish naturalist who worked mainly on Diptera and Hymenoptera. Biography Zetterstedt studied at the University of Lund, where he was a pupil of Anders Jahan Retzius. He received the title of professor in 1822 and succeeded Carl Adolph Agardh as professor of botany and practical economy in 1836, retiring as emeritus in 1853. In 1831, he was elected a member of the Royal Swedish Academy of Sciences. He is best known as an entomologist.

Phratora Vitellinae
''Phratora vitellinae'', the brassy leaf beetle, formerly ''Phyllodecta vitellinae'', is a beetle of the family Chrysomelidae found in Europe and Asia. It feeds on ''Populus'' and ''Salix'' species. The evolution of its host plant preferences and the mechanism by which it uses host plant chemicals to make a larval defensive secretion have been the subject of intense study by research groups in Europe and the Nordic countries. Description ''Phratora vitellinae'' adults range from 3.5–5.2 mm long. The opaque forewings (elytra) show longitudinal rows of clearly visible dots. Adults typically show metallic blue, green, or bronze colors. Adults show copper or purple colors at high elevations or in Arctic regions. One way to distinguish among adult ''Phratora'' beetles co-occurring on the same host plant is to gently squeeze the abdomen of females until the morphology of the genitalia can be observed from the ventral side. ''Phratora vitellinae'' females possess a wide smooth s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diptera Of Europe
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] |

Royal Entomological Society Of London
The Royal Entomological Society is devoted to the study of insects. Its aims are to disseminate information about insects and improving communication between entomologists. The society was founded in 1833 as the Entomological Society of London. It had many antecedents beginning as the Society of Entomologists of London. History The foundation of the society began with a meeting of "gentlemen and friends of entomological science", held on 3 May 1833 in the British Museum convened by Nicholas Aylward Vigors with the presidency of John George Children. Those present were the Reverend Frederick William Hope, Cardale Babington, William Yarrell, John Edward Gray, James Francis Stephens, Thomas Horsfield, George Thomas Rudd and George Robert Gray. Letters of Adrian Hardy Haworth, George Bennett and John Curtis were read where they expressed their regrets to be unable to attend the meeting. They decided that a society should be created for the promotion of the science of entomology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handbooks For The Identification Of British Insects
''Handbooks for the Identification of British Insects'' is a series of books produced by the Royal Entomological Society (RES). The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information. The series also includes several Check Lists of British Insects. All books contain line drawings, with the most recent volumes including colour photographs.

Chrysomela Aeneicollis
''Chrysomela aeneicollis'' is a species of leaf beetle in the family Chrysomelidae. This organism has been used as a model for studies of natural selection in nature. It is currently being investigated to study effects of environmental change on insect populations, and the evolutionary significance of variation at genes affecting metabolism and the response to stress. It has been included as a study species in the California Conservation Genomics Project, due to its presence in multiple California ecoregions and extensive knowledge of genetic variation, evolutionary ecology, and interactions with other species. Information about its range and comparisons with closely related species can be found in a review of the genus '' Chrysomela'' published in the Canadian Entomologist. Distribution ''Chrysomela aeneicollis'' is found in western North America. Populations occur in cooler habitats in coastal regions from northern California to British Columbia, or at high elevations in the Roc ...

Phratora Vulgatissima
Phratora is a genus of leaf beetles. It is synonymous to ''Phyllodecta'' . European ''Phratora'' species can be distinguished based on morphology of female genitalia., but they differ little in size and body form and most show metallic coloration. Distribution ''Phratora'' species are found in the Northern Hemisphere in areas that tend to be cool and moist where their host plants thrive. They are usually found in Northern and Southern Europe, China and Japan, and in Canada and the United States of America. Host plants Species in this genus are of considerable interest to evolutionary ecology researchers because they vary with respect to host plant preference and chemistry of their larval defensive secretions. ''Phratora'' species are known to feed on willows ('' Phratora americana, P. frosti, P. interstitialis, P. tibialis, Phratora vitellinae, Phratora vulgatissima, P. polaris, P. purpurea''), poplars (''Phratora laticollis, P. atrovirens, Phratora vitellinae, P ...

Hoverflies
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mamma ...
