10 Lines on Mosquito – A Comprehensive Essay
In the heart of every Indian summer evening, we have all found ourselves waving our hands or swatting away at tiny winged pests buzzing around our ears. These small insects, known as mosquitoes, are perhaps one of the most ubiquitous creatures in our daily lives, particularly in the tropical and sub-tropical regions of India. Almost every Indian child has a memory of trying to sleep under a mosquito net or rubbing odomos cream on exposed skin. Though they may seem insignificant, mosquitoes have a profound influence on our environment, our health, and our way of life. To truly manage their presence and minimise their negative impact, it is important for us to study mosquitoes in detail – their biology, behaviour, ecological role, and the ways we can protect ourselves from them.

Physical Attributes and Taxonomy
Mosquitoes are insects belonging to the order Diptera, which means “two-winged” in Greek. Unlike butterflies, which belong to Lepidoptera, or bees, which are Hymenoptera, the mosquito’s family, Culicidae, is easily distinguishable by its slender body and delicate wings. If you take a closer look at a mosquito (without it flying away, of course!), you’ll notice three main body parts – the head, thorax, and abdomen. The head houses two large compound eyes that allow them to sense even the slightest movement. There is also a pair of antennae, which works like a sensitive radar to sense chemicals, heat, and motion in the environment.The most famous feature of the mosquito is its proboscis—a long, tube-like mouthpart built for piercing skin and sucking fluids. While both males and females have this structure, only the female's is robust enough to draw blood, as she needs extra nutrition for egg development. Finally, a mosquito’s body is supported by six thin legs and is enclosed in an exoskeleton that may feel soft to us but is actually quite protective for its miniature size.

The Life Cycle of the Mosquito
Even though mosquitoes are everyday creatures, their life journey is quite fascinating! They undergo a complete metamorphosis, passing through four distinct stages: egg, larva, pupa, and adult.It all starts when a female mosquito lays her eggs on the surface of stagnant water, such as puddles formed after monsoon rains, water collected in old tyres, plant pots, or even uncovered buckets at home. Within a day or two, the eggs hatch into wriggling larvae, popularly called “wrigglers” by Indian children. These larvae are aquatic; they feed on tiny organic particles in the water and breathe air through siphon tubes. After about a week, they transform into pupae (‘tumblers’), and then, in a day or two, a full-grown mosquito emerges.
Environmental conditions such as temperature and humidity play a big role in determining how quickly the mosquito’s life cycle progresses. For instance, in the heat and moisture of Mumbai’s July humidity, mosquitoes may complete their life cycle in just over a week, while in the dryer chill of North Indian winters, development slows down considerably. Interestingly, male mosquitoes live only a few days, as their main function is to mate, whereas females live longer—sometimes up to a month—depending on food and risks.

Behaviour, Habitat and Feeding Patterns
Mosquitoes are creatures of habit and display unique behaviour depending on their species and the environment. India’s warm climate, combined with the seasonal monsoon, provides an ideal setting for them to thrive. That is why we hear about “dengue season” in the newspapers whenever the rains return. They are rarely found in extremely cold or dry places—something the hill stations of Himachal or the deserts of Rajasthan can attest to.Both male and female mosquitoes mainly feed on the nectar of flowers, just like bees. However, the female’s need for protein to produce eggs leads her to seek blood from human or animal hosts. This hunt starts as she senses carbon dioxide from our breath, warmth from our bodies, and odours from sweat or perfume. Dark clothes and exposed skin also make us easy prey, which is why our elders always tell us to wear long sleeves in the evenings.
Most mosquitoes are most active at dawn and dusk. Their preference for these timings protects them from predators and the heat of the day. If you’ve ever tried to outrun a mosquito in the evening, you’ll know how fast and quiet they can be. A mosquito, in fact, can cover several kilometres seeking food or a mate, spreading out from its birthplace in search of fresh victims!

Mosquitoes in the Web of Life
Despite being viewed only as nasty pests, mosquitoes have an important ecological role. Their larvae serve as food for many freshwater creatures, such as fish and tadpoles found in village ponds. Adult mosquitoes, in turn, are eaten by birds like swallows and bats, and even creatures such as dragonflies and frogs. So, completely wiping out mosquitoes would disturb the delicate balance of nature.Fascinatingly, while we know mosquitoes for biting, most feed only on nectar, and in doing so, they act as accidental pollinators for certain wildflowers found in Indian wetlands. Some unique Himalayan flora depend on mosquitoes and their kin for pollination, which is a fact not known to many. This shows that nature often gives even the “villains” of our story a redeeming quality.

Mosquitoes and Human Health
Mosquitoes are known as the deadliest animals on Earth—not because of their bite, but because of the diseases they carry. In India, the list is long and troubling: malaria, dengue, chikungunya, filaria, and Japanese encephalitis. These illnesses are responsible for thousands of deaths every year, especially during the monsoon and post-monsoon seasons. The National Vector Borne Disease Control Programme (NVBDCP), under the Government of India, regularly issues warnings and advisories regarding these diseases.The way mosquitoes cause disease is both simple and sinister. When a female mosquito bites, she injects some saliva into our blood to prevent clotting. If she is carrying a virus or parasite, such as the Plasmodium that causes malaria, that gets transmitted to us. No one who has suffered the high fever and shivering of malaria, or the aching joints of chikungunya, will ever brush off mosquitoes as harmless.
Apart from diseases, even simple mosquito bites can cause itching, redness, and allergic reactions. And who hasn’t lost sleep because of their endless buzzing on a humid night? The psychological impact—irritation, restlessness, lack of sleep—is real and affects our quality of life.

Safeguarding Against Mosquitoes – Prevention and Control
Given their impact on both health and comfort, it becomes necessary to adopt strategies to protect ourselves and our communities. On a personal level, parents in India often make their children sleep under mosquito nets or insist on applying repellents like neem oil, citronella, or commercial creams. Simple measures—such as wearing full-sleeved clothes during evenings, installing mesh screens on doors and windows, and using electric mosquito racquets—can go a long way.However, individual efforts alone are not sufficient. Community participation is crucial in controlling mosquito populations. The Swachh Bharat Abhiyan’s focus on cleanliness also addresses this by encouraging the elimination of stagnant water around homes, which breeds mosquitoes. Municipalities now regularly fog neighbourhoods with insecticides, especially in urban areas like Delhi and Bengaluru. Some cities have adopted innovative larvicidal treatments in public drains and water bodies.
On the scientific front, India has participated in trials involving genetically modified mosquitoes that cannot reproduce, thus reducing populations. Newer mosquito traps and monitoring techniques are being tried in cities like Pune. The National Institute of Malaria Research in Delhi is developing advanced vaccines, and awareness campaigns are conducted in rural schools and urban colonies to educate citizens about simple actions that can prevent outbreaks.
