What do mosquitoes look like?
The mosquito is tiny, with thin legs and long, thin wings. They have a narrow body, a small head, and a pointed proboscis (mouthpart) that they use to suck blood from their hosts. Most mosquito species have a dark coloration, with brown or black bodies and legs. Some species have distinctive markings on their wings or bodies that help to identify them.

What to know about mosquitoes
Characteristics of mosquitoes vary by species, but they share common traits that make them effective at survival and reproduction.
A major characteristic of mosquito species is their attraction to carbon dioxide, which helps them locate human and animal hosts. Their ability to detect human odor plays a crucial role in their survival and success. They can also adapt well to different climates, making them a persistent pest worldwide.
Mosquito life cycle
Mosquitoes go through four stages in their life cycle: egg, larva, pupa, and adult. The egg stage lasts about two to three days, after which the larvae hatch. During the larval stage, the mosquito lives in water and molts several times as it grows. After about a week, the larva transforms into a pupa, during which it does not feed and is relatively inactive. Finally, the adult mosquito emerges from the pupa, and the cycle starts anew. The average lifespan of a mosquito is around two to three weeks, but some species can live for up to a month.
The mosquito diet
These tiny pests typically feed on nectar and other plant juices to get the necessary sugar and nutrients. However, the female mosquito requires a blood meal to produce eggs. They use their proboscis to pierce the skin of animals, including humans, and then suck the blood. Males do not feed on blood and only feed on plant juices.
Habitats
The mosquito species are highly adaptable creatures that can thrive in a variety of environments. These tiny insects can be found in various habitats, from wetlands and swamps to urban areas and even deserts. They are attracted to areas with high humidity and temperatures, making warm and damp environments ideal for their growth and reproduction. They require a source of standing water to lay their eggs, and for the larvae to develop, so they are commonly found near bodies of water such as ponds, lakes, and marshes. In urban areas, these pests can breed in standing water sources such as bird baths, flower pots, and gutters.
Mosquito behaviour and activity patterns
Mosquitoes are highly sensitive to environmental conditions such as humidity, temperature, and light. This influences their feeding, breeding, and resting habits. Some species prefer warm, tropical climates, while others thrive in temperate regions. Mosquito biology plays a critical role in their survival, enabling them to detect hosts and find suitable breeding sites. Understanding the general characteristics of mosquitoes can help in controlling their populations and reducing the risk of mosquito-borne diseases.
When are mosquitoes most active?
Most mosquito species are most active during dawn and dusk when temperatures are lower and humidity levels are higher. However, some species, such as Aedes aegypti and Aedes albopictus, are also active during the day. Factors like light and wind speed can impact their activity, as mosquitoes prefer calm, shaded areas for feeding and resting. You should take precautions during peak activity times to help avoid bites and potential exposure to mosquito-borne diseases.
How do mosquitoes find their hosts?
Mosquitoes use a combination of sensory cues to locate their hosts. They detect carbon dioxide exhaled by humans and animals from a distance, and once closer, they rely on human odor and body heat to home in on their target. Certain mosquito species, such as Anopheles gambiae, are highly specialized in tracking humans, making them efficient disease carriers.
Common types of mosquitoes
Mosquito species vary in their habitat, behavior, and disease transmission potential. Some of the most common and medically significant species include:
Culex
Culex mosquitoes are the most common mosquito type found in the United States and can transmit diseases such as West Nile virus and encephalitis to humans.
Aedes
Aedes encompass the Asian tiger mosquito and the yellow fever mosquito. They have distinctive white and black striped legs and can spread diseases such as dengue fever, chikungunya, Zika fever, and yellow fever viruses.
Anopheles
The Anopheles mosquito can be found mostly in tropical and subtropical regions and is responsible for most malaria cases.
Mosquito evolution and history
Mosquitoes have existed for millions of years. Their adaptability has allowed them to evolve alongside humans and animals, making them one of the most persistent insect species on Earth. Over time, different species have developed specialized behaviors and mosquito features that aid their survival, such as resistance to insecticides and heightened host detection abilities.
Diseases from mosquitoes
Some mosquito species can carry pathogens that transmit diseases such as malaria, dengue fever, Zika virus, West Nile virus, and chikungunya. Symptoms of these illnesses can vary depending on the specific disease, but can include fever, headache, joint pain, rash, and fatigue. In severe cases, complications such as organ failure or even death can occur. For mosquito prevention, it is essential to take proactive steps to reduce the risk of bites and illnesses. If you experience these symptoms after being bitten by a mosquito, it is best to seek medical attention immediately.
Common breeding spots around homes
Mosquitoes rely on stagnant water to lay their eggs, making any source of standing water a potential breeding ground. Common household breeding spots include:
- Birdbaths and fountains
- Clogged gutters
- Flower pots and plant saucers
- Old tires and containers
- Ponds, ditches, and marshy areas
Regularly emptying or treating these water sources can help reduce mosquito populations, limit the spread of mosquito-borne diseases, and protect public health.
Frequently asked questions
What is a mosquito attracted to?
A mosquito can be attracted to body heat, carbon dioxide, and lactic acid. They are also attracted to certain fragrances, such as perfumes, scented lotions, and dark-colored clothing.
Why are mosquito bites itchy?
Mosquito bites are itchy because when a mosquito bites a person, it injects saliva into the skin, which contains several foreign substances, including an anticoagulant to prevent blood clotting. The body's immune system recognizes these foreign substances and reacts by releasing histamines, which cause itchiness, redness, and swelling around the bite area. The severity of the reaction to mosquito bites varies from person to person.
When does mosquito season start?
Mosquito season can vary depending on the location and climate. In general, mosquito season starts in the spring or early summer when temperatures warm up and lasts until the fall or first frost. In some areas, mosquito season may start earlier or last longer due to warmer temperatures.

What characteristics do mosquitoes have?
Mosquitoes share several defining traits that aid their survival and efficiency as disease vectors. Small, slender bodies with long legs and narrow wings are a common factor in the mosquito's physical description. They have specialized mouthparts, known as a proboscis, designed for blood-feeding, and their sensory organs help them detect human odor and body heat, allowing them to locate hosts efficiently. Mosquitoes are also highly adaptable and can breed in small amounts of stagnant water, making them difficult to control in urban and rural environments.
What are the common features between mosquitoes and houseflies?
Mosquitoes and houseflies both belong to the Diptera order, but they differ significantly. Certain features of mosquitoes, like having two wings and undergoing metamorphosis, are shared with houseflies. Both can spread diseases and adapt to various environments. However, mosquitoes rely on blood meals for reproduction, unlike houseflies, which feed on decaying matter.
