Fly (pentop Computer)
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 more than 150,000 species including horse-flies, crane flies, hoverflies, mosquitoes and others. 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 manoeuvrability 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 larval food-source and the larvae, which lack true limb ...

Triassic
The Triassic ( ; sometimes symbolized 🝈) is a geologic period and system which spans 50.5 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.4 Mya. The Triassic is the first and shortest period of the Mesozoic Era and the seventh period of the Phanerozoic Eon. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halteres
''Halteres'' (; singular ''halter'' or ''haltere'') (from , hand-held weights to give an impetus in leaping) are a pair of small club-shaped organs on the body of two Order (biology), orders of flying insects that provide information about body rotations during flight. Insects of the large order Diptera (flies) have halteres which evolved from a pair of ancestral hindwings, while males of the much smaller order Strepsiptera (stylops)Merriam-Webster: stylops broadly: an insect of the order Strepsiptera/ref> have halteres which evolved from a pair of ancestral forewings. Halteres oscillate rapidly along with the wings and operate like vibrating structure gyroscopes: any rotation of the plane of oscillation causes a force on the vibrating halteres by the Coriolis effect. The insect detects this force with sensory organs called campaniform sensilla and chordotonal organs located at the base of the halteres and uses this information to interpret and correct its position in space. ...

Hoverflies
Hoverflies, also called flower flies or syrphids, make up the insect family (biology), family Syrphidae. As their common name suggests, they are often seen Hover (behaviour), 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, specifically detritivores, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores, preying on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered crop pest (organism), pests, so the aphid-eating larvae of some hoverflies are economically and ecologically important. The larvae are potential agents for use in biological control, while the adults are pollinators. About 6,000 species in 200 genus, genera have been described. Hoverflies are common throughout the world and can be found on all continents except Antarctica. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crane Flies
A crane fly is any member of the dipteran superfamily Tipuloidea, which contains the living families Cylindrotomidae, Limoniidae, Pediciidae and Tipulidae, as well as several extinct families. "Winter crane flies", members of the family Trichoceridae, are sufficiently different from the typical crane flies of Tipuloidea to be excluded from the superfamily Tipuloidea, and are placed as their sister group within Tipulomorpha. Two other families of flies, the phantom crane flies ( Ptychopteridae) and primitive crane flies ( Tanyderidae), have similar common names due their similar appearance, but they are not closely related to true crane flies. The classification of crane flies has been varied in the past, with some or all of these families treated as subfamilies, but the following classification is currently accepted. Species counts are approximate, and vary over time. ; Infraorder Tipulomorpha : Superfamily Tipuloidea (Typical Crane Flies) :: Family Cylindrotomidae (Cy ...

Blister Beetle
Blister beetles are beetles of the family (biology), family Meloidae, so called for their defensive secretion of a blistering agent, cantharidin. About 7,500 species are known worldwide. Many are conspicuous and some are aposematism, aposematically colored, announcing their toxicity to would-be predators. Description Blister beetles are hypermetamorphic, going through several larval stages, the first of which is typically a mobile triungulin. The larvae are insectivorous, mainly attacking bees, though a few feed on grasshopper eggs. While sometimes considered parasitoids, in general, the meloid larva apparently consumes the immature host along with its provisions, and can often survive on the provisions alone; thus it is not an obligatory parasitoid, but rather a facultative parasitoid, or simply a kleptoparasite. The adults sometimes feed on flowers and leaves of plants of such diverse families as the Amaranthaceae, Asteraceae, Fabaceae, and Solanaceae. Cantharidin, a poisono ...

Lytta Vesicatoria
''Lytta vesicatoria'', also known as the Spanish fly, is an aposematic emerald-green beetle in the blister beetle family (Meloidae). It is distributed across Eurasia. The species and others in its family were used in traditional apothecary preparations as "Cantharides". The insect is the source of the terpenoid cantharidin, a toxic blistering agent once used as an exfoliating agent, anti-rheumatic drug and an aphrodisiac. The substance has also found culinary use in some blends of the North African spice mix '' ras el hanout''. Its various supposed benefits have been responsible for accidental poisonings. Etymology and taxonomy The generic name is from the Greek λύττα (''lytta''), meaning martial rage, raging madness, Bacchic frenzy, or rabies. The specific name is derived from Latin ''vesica'', blister. ''Lytta vesicatoria'' was formerly named ''Cantharis vesicatoria'', although the genus '' Cantharis'' is in an unrelated family, Cantharidae, the soldier beetles. ...

House-fly
The housefly (''Musca domestica'') is a fly of the suborder Cyclorrhapha. It possibly originated in the Middle East, and spread around the world as a commensal of humans. Adults are gray to black, with four dark, longitudinal lines on the thorax, slightly hairy bodies, and a single pair of membranous wings. They have red compound eyes, set farther apart in the slightly larger female. The female housefly usually mates only once and stores the sperm for later use. It lays batches of about 100 eggs on decaying organic matter such as food waste, carrion, or feces. These soon hatch into legless white larvae, known as maggots. After two to five days of development, these metamorphose into reddish-brown pupae, about long. Adult flies normally live for two to four weeks, but can hibernate during the winter. The adults feed on a variety of liquid or semi-liquid substances, as well as solid materials which have been softened by their saliva. They can carry pathogens on their bodie ...

Moth Fly
Psychodidae, also called drain flies, sink flies, filter flies, sewer flies, or sewer gnats, is a family of true flies. Some genera have short, hairy bodies and wings, giving them a "furry" moth-like appearance, hence one of their common names, moth flies. Members of the sub-family Phlebotominae, which are hematophagous (feed on blood), may be called sand flies in some countries, although this term is also used for other unrelated flies, such as horse flies (Tabanidae) and no-see-ums (Ceratopogonidae). There are more than 2,600 described species worldwide, most of them native to the humid tropics. This makes them one of the most diverse families of their order. Drain flies sometimes inhabit plumbing drains and sewage systems, where they are harmless, but may be a persistent annoyance. Life cycle The larvae of the subfamilies Psychodinae, Sycoracinae and Horaiellinae live in aquatic to semi-terrestrial or sludge-based habitats, including bathroom sinks, where they feed on ...

Bee Fly
The Bombyliidae are a family (biology), family of fly, flies, commonly known as bee flies. Some are colloquially known as bomber flies. Adults generally feed on nectar and pollen, some being important pollinators. Larvae are mostly parasitoids of other insects. Overview The Bombyliidae are a large family (biology), family of fly, flies comprising hundreds of genus, genera, but the life cycles of most species are poorly known, or not at all. Their size varies between species ranging from 2 mm long to a 40 mm wingspan making them some of the largest flies. When at rest, many species hold their wings at a characteristic "swept back" angle. Adults generally feed on nectar and pollen, some being important pollinators, often with spectacularly long proboscises adapted to plants such as ''Lapeirousia'' species with very long, narrow floral tubes. Unlike butterflies, bee flies hold their proboscis straight, and cannot retract it. Many Bombyliidae superficially resemble bees and accord ...

Robber Fly
The Asilidae are the robber fly family, also called assassin flies. They are powerfully built, bristly flies with a short, stout proboscis enclosing the sharp, sucking Insect mouthparts#Hypopharynx, hypopharynx. The name "robber flies" reflects their expert predatory habits; they feed mainly or exclusively on other insects and, as a rule, they wait in ambush and catch their prey in flight. Overview The Asilidae are a family in the Order (biology), order fly, Diptera, the true flies. The common name for members of the family is robber flies, a name first suggested in 1869 by Alpheus Spring Packard, Alpheus Packard based on the German "Raubfliegen" (predatory flies). The Asilidae are Cosmopolitan distribution, cosmopolitan, with over 7000 described species. Pierre André Latreille, Latreille was the authority for establishing the family in 1802. The Asilidae, together with Bombyliidae and Therevidae, are the most representative families of the superfamily of Asiloidea and they for ...
