where do adult insects emerge from?

Depends of what kind of metamorphosis the insect has. If it has a complete metamorphosis (like butterflies), adults emerge from a chrysalis. Others that have a gradual metamorphosis(like grasshoppers), just grow and change of exoskeleton as they do it, having small gradual changes in them.

In the UK we call it 'cuckoo spit' and it is really the home of the frog hopper larva, it makes the foam from sap it sucks from the plant. When it becomes an adult it is a red beetle.

Mosquitoes Need Water: All mosquitoes have four stages of development-egg, larva, pupa, and adult-and spend their larval and pupal stages in water. The females of some mosquito species deposit eggs on moist surfaces, such as mud or fallen leaves, that may be near water but dry. Later, rain or high tides reflood these surfaces and stimulate the eggs to hatch into larvae. The females of other species deposit their eggs directly on the surface of still water in such places as ditches, street catch basins, tire tracks, streams that are drying up, and fields or excavations that hold water for some time. This water is often stagnant and close to the home in discarded tires, ornamental pools, unused wading and swimming pools, tin cans, bird baths, plant saucers, and even gutters and flat roofs. The eggs deposited on such waters soon hatch into larvae. In the hot summer months, larvae grow rapidly, become pupae, and emerge one week later as flying adult mosquitoes. A few important spring species have only one generation per year. However, most species have many generations per year, and their rapid increase in numbers becomes a problem

If you mean the biological process, then these are the sites:\nfor definitions look at\nhttp://www.google.com/search?hl=en&lr=&rls=GGLD,GGLD:2004-33,GGLD:en&oi=defmore&defl=en&q=define:metamorphosis\nFor other information\nMetamorphosis in a process in biology by which individual physically develops after birth or hatching involving significant change in form as well as growth and differentiation. It usually accompanies a change of habitat or of habits but may occur without such change. It was once thought that in those cases where the animal's habitat remains unchanged metamorphosis followed a series of forms representing evolutionary ancestors of the species in question (see ontogeny recapitulates phylogeny), but this is no longer thought to be true.\n\nThe first type of metamorphosis is illustrated by many insects and by amphibians. Immature dragonflies are aquatic though the adults are flying insects, and frogs undergo a metamorphosis from an aquatic tadpole to an amphibious adult form. Change of habits is illustrated by the transformation of the free-swimming young of many aquatic invertebrates into sessile adults (eg sea squirts), and the development of butterflies and moths from caterpillars with chewing mouthparts into flying insects with sucking mouthparts.\n\nThe second type is illustrated by many crustacean species, whose young undergo significant physical metamorphosis without changing habits or habitat significantly.\n\nhttp://en.wikipedia.org/wiki/Metamorphosis_%28biology%29\n\n\nIf you are referring to the work of Kafka by this name, then see these:\nwww.sparknotes.com/lit/metamorph/\nwww.gradesaver.com/classicnotes/titles/metamorphosis/

The adult mosquito is entirely terrestrial and is capable of flying long distances. Both females and males feed on nectars which they use for energy. Males and females mate during the first 3 to 5 days after they have emerged. Females mate only once. Males generally live for only a week. Only the females feed on blood, which is what is occurring when they are biting. Females evidently gain little nourishment from blood meals but need them in order to develop eggs. Many mosquitoes feed on any warm-blooded bird or mammal. However, some prefer cold-blooded animals. Some species also prefer birds and seldom feed on mammals, which is the case with Culex spp. mosquitoes which are known to transmit the West Nile virus (WNV). Unfortunately many species feed on a wide range of warm-blooded mammals and humans are often attacked. Once a female has completely engorged she flies to a shaded environment until her eggs are completely developed, usually 3 to 5 days. Once the eggs are developed the female is called a gravid female and she begins to search for a desirable place to lay her eggs. If a female survives her egg laying activities, she will very soon start searching for another blood meal after which she will lay another batch of eggs. She does not need to mate a second time. Generally a female will only live long enough to lay 1 to 3 batches of eggs. \n\nMost mosquito species are actively searching for a blood meal in the evening hours from just before dark until 2 to 3 hours after dark. During the daytime the females normally rest in cooler vegetated areas where the humidity is higher and they are protected from drying out. Females will often bite in the daytime if humans or animals invade the wooded areas where they are resting. However, Aedes albopictus is an aggressive biter which prefers to feed during the daylight hours and is often a nuisance in urban areas.

Many species of insects have evolved a strategy called diapause. Diapause is a suspension of development that can occur at the embryonic, larval, pupal, or adult stage, depending on the species. In some species, diapause is facultative and occurs only when induced by environmental conditions; in other species the diapause period has become an obligatory part of the life cycle. The latter is often seen in temperate-zone insects, where diapause is induced by changes in the photoperiod (the relative lengths of day and night). The day length when 50% of the population has entered diapuase is called the critical day length, and it is usually quite sudden. Insects entering diapuse when the day length falls below this threshold are called long day insects. Those insects that develop normally when there are only a few hours of sunlight and that enter diapuse when exposed to longer days are called short-day insects. The critical day length is a genetically determined property.\n\nDiapause is not a physiological response brought about by harsh conditions. Rather, it is brought about by token stimuli that presage a change in the environment. Diapause begins before the actual severe conditions arise. Diapause is especially important in temperate zone insects that overwinter. Embryos of the silkworm moth Bombyx mori overwinter as embryos, entering diapuse just before segmentation. The gypsy moth Lymantia dispar initiates its diapause as a fully formed larva, ready to hatch as soon as diapause ends. Other insects experience diapause as eggs, pupae, or even as adults.

Its called Ecdysis.Ecdysis is the moulting of the cuticle or the exoskeleton.Higher insects have only 4-5 moultings whereas lower insects have till 15.As the exoskeleton is hard its difficult for the insect to grow so it moults periodically to grow.They grow a new exoskeleton later.

most likely from the dead "meese" becaue flies come from maggots, and flies can seem to just grow from dead stuff....

They hatch from eggs. At first they are little larvae (squiggly white wormy things), then they pupate, metamorphose, and emerge as flies.

EMERGENTS\nThe emergents consist of the tops of the tallest trees, which are much higher than the average canopy height (ranging up to 270 feet or 81 m). It houses many birds (like the scarlet macaw), insects, and more. \n\n\nCANOPY\nThe canopy is the name given to the upper parts of the trees (about 65 to 130 feet or 20 to 40 m tall). This leafy environment is full of life: insects, arachnids, many birds (like the keel-billed toucan, the scarlet macaw, the cuckoo, and the hornbill), mammals (like the howler monkey, which is the second-loudest animal in the world, and the orangutan), reptiles (like snakes and lizards), and others. Plants in the canopy include thick, snake-like vines and epiphytes ("air plants") like mosses, lichens, and orchids (which grow on trees). \n\n\nUNDERSTORY\nThe understory is a dark, cool environment that is under the leaves but over the ground. Most of the understory of a rainforest has so little light that plant growth is limited. There are short, leafy, mostly non-flowering shrubs, small trees, ferns, and vines (lianas) that have adapted to filtered light and poor soil. Some of these plants include ferns, palms, philodendrons, and heliconias. Animals in the understory include insects (like beetles and bees), arachnids, snakes, lizards, and small mammals (like the kinkajou) that live on and in tree bark. Some birds (like antbirds) live and nest within tree recesses and eat the abundant insects. Some larger animals, like jaguars, spend a lot of time on branches in the understory, surveying the area, looking for prey. \n\n\nFOREST FLOOR\nThe floor of the forest is teeming with animal life, especially insects and arachnids (like tarantulas). The largest animals in the rainforest generally live here, including gorillas, anteaters, wild boars, tapirs, jaguars, and people.

no, I don't think they arrived fully formed male/female anything.  the genders started as single cells that split off in asexual reproduction, then perhaps some hermophodite reproduction then perhaps 2 genders.  There are some worms that can fertilize themselves.

Identification\nFireflies are winged beetles. Adults are 7/16 to 9/16 inch long, elongate and very soft-bodied, with the pronotum extending forward over the head, resulting in the head being largely or entirely concealed when viewed from above. The pronotum is reddish-yellow with a black spot in the center. Brownish-black wing covers have a light yellowish area entirely around them except in front. The luminous lower end of a male firefly's abdomen is yellowish-green, whereas the female has a smaller splotch. It is these "taillight" segments where living light is produced. Eggs secreted in the earth may show a touch of luminescence. Larvae are multi-legged, turtle-like creatures with tiny spots on their underside, softly glowing like view holes in the furnace door. Wingless females and luminescent larvae are often called "glowworms." \n\nLife Cycle and Habits\nFemales deposit eggs in the earth (damp soil), and in about three weeks young sowbug-like larvae appear. The larva is a voracious predator that eats snails, slugs, cutworms, mites and pollen. They inject strong paralytic and digestive juices into their prey and then suck the dissolved body contents, leaving an empty skin or shell. Larvae live one to two years underground and in late spring build a marble-sized mud house around themselves. They then change to a pupa. In about 10 days, new adult beetles emerge with a lifespan of only a few days to a week. They emerge in early summer and remain active throughout August. When a firefly is under stress such as being caught in a spider's web, its taillight glows brightly. Even the shock of a firecracker or thunder may cause a field of fireflies to flash in unison. Ordinarily, the flashing signal is used to find a mate. The pattern of flashing between sexes is fixed. On a relatively cool night, some species wait 5.5 seconds then emit a single short flash. The warmer the weather, the faster the exchange. Other species may wait one second and then hold the flash for a full second. Some tropical species congregate in large numbers and flash in unison. Usually at dusk, male and female fireflies emerge from the grass. Males fly about 1-1/2 feet above the ground, emitting a single short flash at regular intervals. The flashes are usually male fireflies seeking mates. Males outnumber the females fifty to one. Females climb a blade of grass, flashing when males flash within 10 to 12 feet of the females. Exchanges of signals are repeated to 5 to 10 times until mating occurs. Sometimes females will devour males.

Not around here they aren't. I haven't heard any evidence to say they are, but it is possible. Not very likely however. I would say it is more likely that they are disapearing from a specific place, such as around you, because of changes in the climate, introducion of a new species that is competeing with or eating the bees, or something like that.

The life cycle of the ant consists of four stages: egg, larva, pupa, and adult. Fertilized eggs produce female ants (queens, workers, or soldiers); unfertilized eggs produce male ants. \nEgg: Ant eggs are oval shaped and tiny (they are on the order of 1 mm long, but the queen's egg is many times larger). \n\nLarva: The worm-like larvae have no eyes and no legs; they eat food regurgitated by adult ants. The larvae molt (shed their skin) many times as they increase in size. \n\nPupa: After reaching a certain size, the larva spins a silk-like cocoon around itself (against a solid object, like the wall of the chamber) and pupates. During this time the body metamorphoses (changes) into its adult form. \n\nAdult: The pupa emerges as an adult. The entire life cycle usually lasts from 6 to 10 weeks. Some queens can live over 15 years, and some workers can live for up to 7 years.

Look under leaves, wood, bricks, etc. Many insects like to burrow in tight, protective places. Failing that, check bushes and trees.
