Insect is a living thing from a group of invertebrate animal which have the highest number of species in the world. One of them is mosquito which is known as blood-sucker. The mosquitoes, or a scientific name is Culicidae, are a family of about three and half thousand species within the order Diptera with the two-winged flies. They are more closely related to midges, gnats and crane flies and one of the more primitive families of Diptera. Mosquitoes are not founded in the places that are permanently frozen. That means, the life of mosquitoes is based on the environment condition. Mosquitoes take 3-10 days to complete the life cycle from eggs to adults. There are four distinct stages in life cycle of mosquitoes namely eggs, larves, pupa and adult (refer to Figure 1 in Appendix).
Firstly, the life cycle of the mosquito is laying an egg. Mosquitoes have multi-stage life cycle which can divided into two categories which is flooding water species and standing water species. The life cycle of mosquito depend on where in the environments it laid eggs. For example, flooding water mosquito species likes Culex eggs are laid above the water level as floating raft whereas standing water mosquito species such as Aedes Albopictus laid it eggs near the waters. Based on the Clements (1992) studied that female mosquitoes lay some 50 to 500 eggs at one time, depositing them on water or on sites that will flooded. Each egg is protected by an egg shell, which in many species is elaborately sculpted. This reproduction was happened in every life of mosquito in different subfamily and tribes. The eggs of the mosquito hatched take a periods of time based on the environmental conditions. Based on Clements (1992) study stated that

In conclusion, different types of mosquitoes have a different style to growth. However, it still passes through the same life cycle from eggs to adults.

The Asian Tiger Mosquito commonly thrives in residential areas with shade and anything that can hold water. Cans, buckets, flower vases and other water holding containers (like tires), are suitable breeding sites for this invasive species. The male of this species feeds on nectar from plants, whereas the females feed and depend on blood to help them with the development of their eggs. Females may also feed on nectar also....
higher survivorship in growth and development among them. The results showed that there were no major alterations in growth and development of the larvae when fed with detritus. The results suggested the potential of detritus as a possible food source for the larvae. This would insignificantly limit the extent of growth and development among the larvae. The study concluded that larvae of Sabellaria cementarium are capable of changing their diet and thus utilizing detritus as a food supply (Qian and Chia, 1990).
Mosquitoes have three purposes in the world. The first is to suck blood from multiple diseased animals and spread various infections to humans. The second is to bug, annoy, and make as many people mad as possible. The third is to reproduce and make as many babies as they can to carry on the family tradition. To make a parallel to this topic would like discussing telemarketers. Nearly every aspect of a mosquito has a direct connection to telemarketers such as their nearly countless numbers and their drive to topple the American will. Both of these entities still baffle scholars and researchers to how they happen to be so similar.
People do not need to worry about the male mosquitoes because they do not bite. The females are the biters. They need the protein in blood so their eggs will develop properly.
The adults overwinter in leaf litter and thatch until spring time when the temperature warm up. The adults become active seeking new areas to lay eggs and can be seen walking across pavement. The females lay white, kidney shaped eggs with in grass stems that are hollowed out. It takes about 7-14 days for the white larvae to hatch from the eggs and proceed to live and feed within the grass stem until its third-instar. During the second instars cycle, the larvae eat their way through the grass stem, breaking themselves out. The larvae go on to complete their third instar cycle in the thatch feeding roots and crowns. The larval stage takes about 5 to 8 weeks to complete before pupation occurs in the soil. The pupae are about 1 to 2 inches long and emerge as adults in about 7-10 days. They continue feeding on grass until they find their new overwintering site before temperatures begin to drop

In the article “When Mosquitoes Were Killers in America” by Lauren Tarshis, She makes the statement “Yet mosquitoes are far more than a nuisance.” What she means is that mosquitoes aren't a little bug that just sucks a little blood and can be annoying, but instead it uses all that and more. Mosquitoes have killed millions upon millions of people by spreading disease like malaria. An example of how she supports this claim is in the article, she says “ In this way, bite by itchy bite, 212 million people are infected with malaria every year” (Tarshis 13). And that is only a year with bug spray, shots, and all the other things that help stop mosquitoes. So when the U.S. government tried to save people from these murders little insects. So they

Insects are a vital part of our earth’s ecology. They play various roles as pollinators and as food sources for other animals, without them our food would be drastically reduced. Due to the high amounts of species from the order Insecta, there are key taxonomic features used to classify different specimens from each other.
The seventh major case of Endangered Specie. Specific species of mosquito play host to one phase of various disease organisms they are the cause of major diseases that lead to human compilation. Most people don’t find it wrong to wipe the entire mosquito species in other to prevent human diseases such as sleeping sick, malaria, and human
There are nearly one million species of insects known. Insects are defined by having six legs and a body divided into three segments: head, thorax, and abdomen. Chitin is an organic material that makes up an insects exoskeleton. There are three life cycles of insects, ametabolous or incomplete and paurometabolous or gradual, and homotabolous or complete metamorphosis. These life cycles are important in the aging of insects for aiding in legal investigations, (Houck and Siegel. Entomology).
Several types of mosquitos have been identified as the vector and intermediate host of dirofilaria immitis, including Culex pipiens, Aedes albopictus, Anopheles maculipenis, and Coquilletidia richiardii, allowing the parasite to mature to an infective stage within the mosquito to then infect new hosts via their bite (6). Climate change and urbanization have allowed mosquitos to expand their territory, while global transport of animals has enabled the parasite to infect mosquitos in previously heartworm free areas (5). Under normal circumstances the development of the heartworm larvae within the mosquito is arrested below 57°F limiting the time of infections to the summer month (5). However, in addition to providing irrigation systems as habitat for mosquitos urbanized areas act as heat island extending the time frame of possible dirofilaria immitis transmission significantly (5). As can be seen if figure 1, showing the geographical distribution of heartworm incidents in the U.S. in 2007 , areas with hot and humid climate have the highest number of heartworm infections as they provide favorable co...
They are very popular because they have a relatively short life cycle, which lasts about 9 days. This makes it easy to observe multiple generations in a short period of time. The fly’s life cycle consists of egg, larvae, pupa, and adult stages. At each of these stages of development, Drosophila exhibits different phonotypical identities and mutations. The flies that were crossed contained a genetic mutation called apterous. Apterous can be observed by looking for flied that are missing wings. Flies with apterous will not have any wings. If this mutation is sex linked, it is expected that the male population will only be wingless in the F2 generation. If the mutational is autosomal, it is expected that the mutation to normal fly ratio is
For example, people in love tend to have higher pheromone levels hence are more prone to be bitten by mosquitoes. In the same way, some perfumes can easily attract mosquitoes while others can highly repel mosquitoes depending to the nature of the scent. The hyperhidrosis condition makes individuals sweat more hence such individuals are more prone to be sought by mosquitoes and be bitten. Alcohol tends to attract mosquitoes hence drunkards will be more likely sought and detected by mosquitoes than sober people. Floral scents are normally most attractive to mosquitoes. Mosquitoes are attracted to the salt, potassium and even lactic acid produced by the human
The life cycle of a butterfly is perhaps one of the most beautiful and astounding processes in nature. The four stages a butterfly goes through to become the beautiful flying insects are just as interesting as the vibrant colors and patterns on the wings of the various species of butterflies. The four stages are as follows: the egg, the caterpillar, the pupa, and the emergence of the butterfly. Each stage is vital to the development of the adult butterfly. Perhaps the most interesting piece of the complicated puzzle that is the butterfly life cycle is the process of metamorphosis that happens in stage three. Similar to how a tadpole becomes a frog, a larva (caterpillar) morphs into a beautiful brilliantly colored butterfly.
