Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Endoparasitism
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

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] |
Scarabaeidae
The family Scarabaeidae, as currently defined, consists of over 30,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change in recent years. Several subfamilies have been elevated to family rank (e.g., Bolboceratidae, Geotrupidae, Glaresidae, Glaphyridae, Hybosoridae, Ochodaeidae, and Pleocomidae), and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Bouchard (2011). Description Scarabs are stout-bodied beetles, many with bright metallic colours, measuring between . They have distinctive, clubbed antennae composed of plates called lamellae that can be compressed into a ball or fanned out like leaves to sense odours. Many species are fossorial, with legs adapted for digging. In some groups males (and sometimes females) have prominent horns on the head and/or pronotum to fight over mates or resources.

Phyllopertha Horticola
''Phyllopertha horticola'', the garden chafer or garden foliage beetle, is a beetle from the family Scarabaeidae. ''Phyllopertha horticola'' was described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. Variety *''Phyllopertha horticola'' var. ''ustulatipennis'' A. Villa & G. B. Villa, 1833 Distribution This rather common species is widely widespread in Europe and in Asia, east to Siberia and Mongolia. In the north of Europe their distribution reaches the middle Fennoscandia and includes the British Isles, in southern Europe it mainly occurs in the mountains. It is the only European representative of the genus ''Phyllopertha''. Habitat These beetles inhabit bushes, hedgerows, woodland edges, meadows and fields, from the lowlands to mountainous areas. They also live in parks and gardens, hence the common name of garden chafer.

Amphimallon Solstitialis
''Amphimallon solstitiale'', also known as the summer chafer or European june beetle, is a beetle similar to the cockchafer but much smaller, approximately in length. They are declining in numbers now, but where found they are often seen in large numbers. At dusk they actively fly around tree tops looking for a mate and can often be found drowning in pools of water the following morning. They are also attracted to light and come in through open, lit windows and fly around lamps, making quite a racket while bumping into lights. They are found throughout the Palearctic region (and North America) and, commonly seen from June to August, living in meadows, hedgerows, and gardens, and eating plants and tree foliage. These June Beetles are also pests due to eating the roots of potatoes, rape, and legume plants. This can be a problem since not as many of these plants grow which results in them having pathogens on them, causing the food to dry and die. Because of this, chemical pestic ...

Melolontha Melolontha
The cockchafer, colloquially called Maybug, Maybeetle, or doodlebug, is the name given to any of the European beetles of the genus ''Melolontha'', in the family Scarabaeidae. Once abundant throughout Europe and a major pest in the periodical years of "mass flight", it had been nearly eradicated in the middle of the 20th century through the agricultural intensification and has even been locally exterminated in many regions. However, since pest control was increasingly regulated in the 1980s, its numbers have started to grow again. Taxonomy There are three species of European cockchafers: *The common cockchafer, ''Melolontha melolontha'' *The forest cockchafer, ''Melolontha hippocastani'' *The large cockchafer, ''Melolontha pectoralis'', rarer and less widespread than the other two species. Description Adults of the common cockchafer reach sizes of 25–30 mm; the forest cockchafer is a little smaller (20–25 mm). The two species can best be distinguished by the form ...

Heracleum Sphondylium
''Heracleum sphondylium'', commonly known as hogweed, common hogweed or cow parsnip, is a herbaceous perennial or biennial plant, in the umbelliferous family Apiaceae that includes fennel, cow parsley, ground elder and giant hogweed. It is native to Europe and Asia. The common name eltrot may also be applied, but is not specific to this species. Umbelliferous plants are so named because of the umbrella-like arrangement of flowers they produce. The North American species '' Heracleum maximum'' (also called "cow parsnip") is sometimes included as a subspecies of ''H. sphondylium''. The plant provides a great deal of nectar for pollinators. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. Etymology The species name ''sphondylium'', meaning "vertebrate", refers to the shape of the segmented stem. It was described by Carl Linnae ...

James Francis Stephens
James Francis Stephens (16 September 1792 – 22 December 1852) was an English entomologist and naturalist. He is known for his 12 volume ''Illustrations of British Entomology'' (1846) and the ''Manual of British Beetles'' (1839). Early life Stephens was born in Shoreham-by-Sea and studied at Christ's Hospital. His father was a navy captain William James Stephens (d. 1799) and his mother was Mary Peck (later Mrs Dallinger). He went to school at the Blue Coat School, Hertford and later at Christ's Hospital, London. He was then sent to study under Shute Barrington (1734–1826), the bishop of Durham in 1800. He left in 1807 and worked as a clerk in the Admiralty office, Somerset House, from 1807 to 1845 thanks to his uncle Admiral Stephens. Entomology Stephens took an interest in natural history even as a schoolboy. He wrote a manuscript ''Catalogue of British Animals'' in 1808. He was elected fellow of the Linnean Society on 17 February 1815, and of the Zoological Society o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tegula (insect Anatomy)
A tegula is a small sclerite with innervated bristles situated above the base of the costal vein in the wings of various insects such as Orthoptera, Lepidoptera, Hymenoptera, Diptera, and Auchenorrhyncha, and attached to the antero-lateral portion of the mesonotum. The tegula in locusts is a model system for studying the role of feedback from mechanoreceptors during movement. In locusts, the tegula directly controls flight muscles. The motor neurons that control the activation of wing elevator muscles are phase-locked to the neurons that innervate the tegula such that when the tegula is electrically stimulated the elevator muscles initiate an upstroke. When the tegula is removed, locust flight is clumsy and disordered at first but most animals adapt, suggesting the use of other mechanoreceptors to control flight. The tegula system is also a model for studying the role of neuromodulation for state-dependent motor control. Neural signals from the tegula only initiate wing muscle contr ...
