Blowflies
The Calliphoridae (commonly known as blow flies, blow-flies, carrion flies, bluebottles, greenbottles, or cluster flies) are a family of insects in the order Diptera, with almost 1,900 known species. The maggot larvae, often used as fishing bait, are known as gentles. The family is known to be polyphyletic, but much remains disputed regarding proper treatment of the constituent taxa, some of which are occasionally accorded family status (e.g., Bengaliidae and Helicoboscidae). The name blowfly comes from an older English term for meat that had eggs laid on it, which was said to be flyblown. The first known association of the term "blow" with flies appears in the plays of William Shakespeare: ''Love's Labour's Lost'', '' The Tempest'', and ''Antony and Cleopatra''. Description Characteristics Calliphoridae adults are commonly shiny with metallic colouring, often with blue, green, or black thoraces and abdomens. Antennae are three-segmented and aristate. The aristae are plu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysomya Megacephala
''Chrysomya megacephala'', more commonly known as the oriental latrine fly or oriental blue fly, is a member of the family Calliphoridae (blowflies). It is a warm-weather fly with a greenish-blue metallic box-like body. The fly infests corpses soon after death, making it important to forensic science. This fly is implicated in some public health issues; it can cause accidental myiasis, and also infects fish and livestock. Description ''Chrysomya megacephalas eggs are "oval with one flat face and another convex". Adult flies reflect a metallic blue-green color on their thorax and abdomen and have yellow gena, or cheeks. Larvae vary in size according to instar and are shaped more thickly towards the rear. ''C. megacephala'' have large red eyes, those of males being close together, and those of females farther apart. The ''cercus'' of the male is longer than that of the female. Distribution and habitat ''Chrysomya megacephala'' has a wide geographical distribution. It is most commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diptera
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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysomya
''Chrysomya'' is an Old World blow fly genus of the family Calliphoridae. The genus ''Chrysomya'' contains a number of species including ''Chrysomya rufifacies'' and '' Chrysomya megacephala''. The term “Old World blow fly” is a derivative of both the associated family, Calliphoridae (blow flies), and the belief that the genus ''Chrysomya'' originated in Asia and migrated to North America only relatively recently. ''Chrysomya’s'' primary importance to the field of medico-criminal forensic entomology is due to the genus’ reliable life cycle, allowing investigators to accurately develop a postmortem interval. ''Chrysomya'' adults are typically metallic colored with thick setae on the meron and plumose arista. The name comes from the word ''chrysos'', meaning “golden” in reference to the metallic sheen of the genus’ species, and ''-mya'', a derivation from the word ''myia'', meaning “fly”.

Myiasis
Myiasis is the parasitic infestation of the body of a live animal by fly larvae (maggots) which grow inside the host while feeding on its tissue. Although flies are most commonly attracted to open wounds and urine- or feces-soaked fur, some species (including the most common myiatic flies—the botfly, blowfly, and screwfly) can create an infestation even on unbroken skin and have been known to use moist soil and non-myiatic flies (such as the common housefly) as vector agents for their parasitic larvae. Because some animals (particularly non-native domestic animals) cannot react as effectively as humans to the causes and effects of myiasis, such infestations present a severe and continuing problem for livestock industries worldwide, causing severe economic losses where they are not mitigated by human action. Although typically a far greater issue for animals, myiasis is also a relatively frequent disease for humans in rural tropical regions where myiatic flies thrive, and ...

Maggot
A maggot is the larva of a fly (order Diptera); it is applied in particular to the larvae of Brachycera flies, such as houseflies, cheese flies, and blowflies, rather than larvae of the Nematocera, such as mosquitoes and crane flies. Entomology "Maggot" is not a technical term and should not be taken as such; in many standard textbooks of entomology, it does not appear in the index at all. In many non-technical texts, the term is used for insect larvae in general. Other sources have coined their own definitions; for example: "The term applies to a grub when all trace of limbs has disappeared" and "Applied to the footless larvae of Diptera".Smith, John. BExplanation of terms used in entomology Brooklyn Entomological Society, 1906. Additionally, in ''Flies: The Natural History and Diversity of Diptera'', the author claims maggots "are larvae of higher Brachycera (Cyclorrhapha)." Maggot-like fly larvae are of significance in ecology and medicine; among other roles, vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arista (insect Anatomy)
In insect anatomy the arista is a simple or variously modified apical or subapical bristle, arising from the third antennal segment. It is the evolutionary remains of antennal segments, and may sometimes show signs of segmentation. These segments are called aristameres. The arista may be bare and thin, sometime appearing no more than a simple bristle; pubescent, covered in short hairs; or plumose, covered in long hairs. The presence of an arista is a feature of the Diptera (flies) suborder Brachycera and may be especially well-developed in some species. It is also present in some members of Hemiptera (true bugs), specifically in the suborder Auchenorrhyncha. The arista is often covered in multiple kinds of sensilla A sensillum (plural ''sensilla'') is an arthropod sensory organ protruding from the cuticle of exoskeleton, or sometimes lying within or beneath it. Sensilla appear as small hairs or pegs over an individual's body. Inside each sensillum there are ..., or sens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schizophora
The Schizophora are a section of true flies containing 78 families, which are collectively referred to as muscoids, although technically the term "muscoid" should be limited to flies in the superfamily Muscoidea; this is an example of informal, historical usage persisting in the vernacular. The section is divided into two subsections, the Acalyptratae and Calyptratae, which are commonly referred to as acalyptrate muscoids and calyptrate muscoids, respectively. The defining feature of the Schizophora is the presence of a special structure used to help the emerging adult fly break free of the puparium; this structure is an inflatable membranous sac called the ptilinum that protrudes from the face, above the antennae. The inflation of the ptilinum (using fluid hemolymph rather than air) creates pressure along the line of weakness in the puparium, which then bursts open along the seam to allow the adult to escape. When the adult emerges, the fluid is withdrawn, the ptilinum collap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calypter
A calypter is either of two posterior lobes of the posterior margin of the forewing of flies between the extreme posterior wing base and the alula, which covers the halteres. The lower calypter is the proximal calypter (synonyms: squama (of some authors), tegula) and the upper calypter is the distal calypter (synonym: squamula). Species of the subsection Acalyptratae are noted for lacking calypters. References * James Francis McAlpine. ''Morphology and Terminology - Adults''. In: J.F. McAlpine, B.V. Peterson, G.E.

Insect Morphology
Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions (called tagmata) (head, thorax, and abdomen), have three pairs of legs, and mouthparts located ''outside'' of the head capsule. It is this position of the mouthparts which divides them from their closest relatives, the non-insect hexapods, which includes Protura, Diplura, and Collembola. There is enormous variation in body structure amongst insect species. Individuals can range from 0.3 mm ( fairyflies) to 30 cm across ( great owlet moth); have no eyes or many; well-developed wings or none; and legs modified for running, jumping, swimming, or even digging. These modifications allow insects to occupy almost every ecological niche on the planet, except the dee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaetotaxy
Chaetotaxy is the arrangement of bristles (macrochaetae) on an arthropod or annelid, or taxonomy based on their position and size. For example, it is important in Diptera, in which group it was formalised by Ernst August Girschner. The term chaetotaxy was later proposed by Carl Robert Osten-Sacken. The chaetotaxy of a fly might include :- acrostichal, dorsocentral, humeral, mesopleural, sternopleural, notopleural, postalar, supraalar and scutellar bristles on the thorax; dorsal, posterodorsal, anterodorsal, ventral, posteroventral and anteroventral bristles on the legs and ocellar, orbital, postvertical, vibrissal, outer vertical and inner vertical bristles on the head. Chaetotaxy is also used in determining homology in certain morphological traits, as well as providing information about the phylogeny between taxa. For example, chaetotaxy has been used to clarify evolutionary relationships in Collembola, as well as identify new species. References *Capinera, J.L. (editor). 2 ...

Antony And Cleopatra
''Antony and Cleopatra'' ( First Folio title: ''The Tragedie of Anthonie, and Cleopatra'') is a tragedy by William Shakespeare. The play was first performed, by the King's Men, at either the Blackfriars Theatre or the Globe Theatre in around 1607; its first appearance in print was in the Folio of 1623. The plot is based on Thomas North's 1579 English translation of Plutarch '' Lives'' (in Ancient Greek) and follows the relationship between Cleopatra and Mark Antony from the time of the Sicilian revolt to Cleopatra's suicide during the War of Actium. The main antagonist is Octavius Caesar, one of Antony's fellow triumvirs of the Second Triumvirate and the first emperor of the Roman Empire. The tragedy is mainly set in the Roman Republic and Ptolemaic Egypt and is characterized by swift shifts in geographical location and linguistic register as it alternates between sensual, imaginative Alexandria and a more pragmatic, austere Rome. Many consider Shakespeare's Cleo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristle
A bristle is a stiff hair or feather (natural or artificial), either on an animal, such as a pig, a plant, or on a tool such as a brush or broom. Synthetic types Synthetic materials such as nylon are also used to make bristles in items such as brooms and sweepers. Bristles are often used to make brushes for cleaning purposes, as they are strongly abrasive; common examples include the toothbrush and toilet brush. The bristle brush and the scrub brush are common household cleaning tools, often used to remove dirt or grease from pots and pans. Bristles are also used on brushes other than for cleaning, notably paintbrushes. Bristles are distinguished as '' flagged'' (split, bushy ends) or ''unflagged;'' these are also known as '' flocked'' or ''unflocked'' bristles. In cleaning applications, flagged bristles are suited for dry cleaning (due to picking up dust better than unflagged), and unflagged suited for wet cleaning (due to flagged ends becoming dirty and matted when wet).
