"Mosquito" is a Spanish or PortuguesePortuguese portugues is a Romance language predominantly spoken in Portugal, Brazil, Angola, Mozambique, Cape Verde, and East Timor. With more than 200 million native speakers, Portuguese is one of the few languages spoken in such widely-distributed parts word meaning little fly, and its use dates back to about 1583Events August 5 Sir Humphrey Gilbert establishes first English colony in North America, at what is now St John's, Newfoundland. Toyotomi Hideyoshi commences construction of Osaka Castle in Japan. King James VI of Scotland signs a charter creating the Toun. In Britain mosquitoes are also known as gnats or midges.
In most female mosquitoes, the mouth parts form a long proboscisIn general, a proboscis is an elongated appendage of a living organism. The most common usage is to refer to the tubular feeding and sucking organ of certain invertebrates like insects, worms and mollusks. The elephant's trunk is also called a proboscis. for piercing the skin of mammals (or in some cases birds or even reptiles and amphibians) to suck their bloodBlood is a circulating tissue composed of fluid plasma and cells ( red blood cells, white blood cells, platelets). Medical terms related to blood often begin in hemo or hemato ( BE: haemo and haemato from the Greek word for "blood". Blood of different spe. The females require protein for egg development, and since the normal mosquito diet consists of nectar and fruit juice, which has no protein, most must drink blood to get the necessary protein. Males differ from females, with mouth parts not suitable for blood sucking. There is one genus of mosquitoes, ToxorhynchitesToxorhynchites, also known as mosquito hawks, are the only species of mosquito that does not suck blood. Rather, it preys on the larvae of other mosquitoes., that never drinks blood. The larvae of these large mosquitoes are predatory on other mosquito larvae.
The mosquito goes through four distinct stages in its life cycle: egg, larva, pupa, and adult. The length of the first three stages is species- and temperature-dependent. Culex tarsalis may complete its life cycle in 14 days at 20°C (68°F) and only ten days at 25°C (77°F). Some species have a life cycle of as little as four days or up to one month. The larvae are the "wigglers" found in puddles or water-filled containers. These breathe atmospheric oxygen through a siphon at the tail end. The pupae are nearly as active as the larvae, but breathe through thoracic "horns" attached to the thoracic spiracles. Most larvae feed on microorganisms, but a few are predatory on other mosquito larvae. Some mosquito larvae, such as those of Wyeomyia live in unusual situations. These mosquito wigglers live either in the water collected in epiphytic bromeliads or inside water stored in carnivorous pitcher plants. Larvae of the genus Deinocerites live in crab holes along the edge of the ocean.
