Milichiidae Fg01
Milichiidae are a family of flies. Most species are very small and dark. Details of their biology have not yet been properly studied, but they are best known as kleptoparasites of predatory invertebrates, and accordingly are commonly known as freeloader flies or jackal flies. However, because of the conditions under which many species breed out, they also are known as filth flies. Affinities and appearance The Milichiidae are a family of flies in the suborder Brachycera. They were at one time included in the family Carnidae. At one time or another they have been assigned to various superfamilies, including Carnoidea, Chloropoidea, and Agromyzoidea. As usual for flies of these groups, Milichiidae imagines are tiny, but their heads are comparatively large, compared to many fly species of the same size, such as those in the family Phoridae. Milichiidae are small-to-very-small flies, usually 1 to 3 mm in length. Typically they are black or at least dark. In some species, such ...

Phoridae
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking to the wing. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to '' Conicera tibialis''. About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan ''Megaselia scalaris''. At 0.4 mm in length, the world's smallest fly is the phorid ''Euryplatea nanaknihali''. Description For terms see Morphology of Diptera Phorid flies are minute or small – 0.5–6 mm (– in) in length. When viewed from the side, a pronounced hump to the thorax is seen. Their colours range from usually black or brown to more rarely yellow, orange, pale grey, and pale white. The head is usually rounded and in some species narrowed towards the vertex. The vertex is flat. In some species, the ocellar callus i ...

Oxyopidae
Lynx spider (Oxyopidae) is a family of araneomorph spiders first described by Tamerlan Thorell in 1870. Most species make little use of webs, instead spending their lives as hunting spiders on plants. Many species frequent flowers in particular, ambushing pollinators, much as crab spiders do. They tend to tolerate members of their own species more than most spiders do, and at least one species has been identified as exhibiting social behaviour. Description There are several genera of Oxyopidae and they differ in their habits and adaptations. Most of them have large spiny bristles on their legs and in many species the bristles form almost a basket-like structure that may assist in confining the prey that they grasp, and protect the spider from its struggles. Most '' Oxyopes'' and '' Hamataliwa'' species are small to medium in size. Lynx spiders, in spite of being largely ambush hunters, are very speedy runners and leapers, alert and with good vision. Oxyopidae in general rely on k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nephilinae
Nephilinae is a spider subfamily of the family Araneidae with seven genera. The various genera in Nephilinae were formerly grouped in the family Nephilidae, and before that in the Tetragnathidae and in the Araneidae (where they have been restored). All nephiline genera partially renew their webs. Spiders in the subfamily Nephilinae are commonly referred to as golden orb-weavers. Reproductive behavior The genera '' Herennia'', '' Nephilengys'' and ''Nephilingis'' display extreme sexually driven selection. The pedipalps of these genera have become highly derived by evolving enlarged, complex palpal bulbs which break off inside the females' copulatory openings after copulation. The broken palps serve as mating plugs, which makes future matings with a mated female more difficult. These genera of spiders also participate in mate guarding; a mated male will stand guard by his female and chase off other males, thereby increasing the mated male's paternity share. Mated males are castrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kleptoparasitism
Kleptoparasitism (etymologically, parasitism by theft) is a form of feeding in which one animal deliberately takes food from another. The strategy is evolutionarily stable when stealing is less costly than direct feeding, which can mean when food is scarce or when victims are abundant. Many kleptoparasites are arthropods, especially bees and wasps, but including some true flies, dung beetles, bugs, and spiders. Cuckoo bees are specialized kleptoparasites which lay their eggs either on the pollen masses made by other bees, or on the insect hosts of parasitoid wasps. They are an instance of Emery's rule, which states that insect social parasites tend to be closely related to their hosts. The behavior occurs, too, in vertebrates including birds such as skuas, which persistently chase other seabirds until they disgorge their food, and carnivorous mammals such as spotted hyenas and lions. Other species opportunistically indulge in kleptoparasitism. Strategy Kleptoparasitism is a fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predator
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and i ...

Climate
Climate is the long-term weather pattern in an area, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude/longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme was the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Labellum (insect Anatomy)
In entomology, the term labellum has been applied variously and in partly contradictory ways. One usage is in referring to a elongation of the labrum that covers the base of the rostrum in certain Coleoptera and Hemiptera. In contrast, the most common current use of the term is in the anatomy of the mouthparts of Diptera, particularly those in which the labium forms the bulk of the proboscis, such as in the housefly family. Typically, the labium is expanded distally into a pair of fleshy labella. In the early twentieth century it was argued that the labella are the modified labial palps, and that point of view still is seen as having merit.Crampton, G. C.; The sclerites of the head and the mouthparts of certain immature and adult insects. Ann. Ent. Soc. Am. 14, pp. 65-103.

Ceratopogonidae
Ceratopogonidae is a family of flies commonly known as no-see-ums, or biting midges, generally in length. The family includes more than 5,000 species, distributed worldwide, apart from the Antarctic and the Arctic. Ceratopogonidae are holometabolous, meaning their development includes four life stages: egg, larva, pupa, and imago or adult. Most common species in warmer climates will take about two to six weeks to complete a life cycle. Both adult males and females feed on nectar. Most females also feed on the blood of vertebrates, including humans, to get protein for egg-laying. Their bites are painful, and can cause intensely itchy lesions. Their mouthparts are well-developed for cutting the skin of their hosts. Some species prey on other insects. Larvae need moisture to develop, but also air and food. They are not strictly aquatic or terrestrial. Some species within the biting midges are thought to be predatory on other small insects. Particularly mosquito larvae have been ...
