Insects are amazing creatures that play a big role in nature. They help break down nutrients and serve as food for many animals. Some insects even help plants by spreading pollen and seeds. But there’s one insect that many people find annoying: the mosquito, or “mozzie” as it’s called in Australia. Mosquitoes can be a nuisance because their bites itch and they buzz around, especially at night. More importantly, some mosquitoes can spread diseases like malaria and dengue fever.
To control mosquito populations and prevent diseases, it’s important to understand their life cycle. Mosquitoes need still water to reproduce. This means water that isn’t moving, like in ponds, puddles, or even in plant pots. After mating, a female mosquito lays her eggs on the water’s surface. These eggs stick together to form what is called an egg raft.
Each egg hatches into a larva. Mosquito larvae look very different from adult mosquitoes. They have long bodies and float at the water’s surface. They breathe through a special tube called a siphon and eat tiny organisms in the water. If they sense danger, they dive below the surface in a wiggly motion, which is why they’re often called “wigglers.” The larval stage lasts about 10 days, during which they grow quickly.
After the larval stage, mosquitoes enter the pupal stage. Pupae don’t eat, but they still need air, which they get at the water’s surface. They are sensitive to changes in their environment and can roll below the surface, earning them the nickname “tumblers.” This stage lasts only a few days before an adult mosquito emerges.
Once they become adults, male mosquitoes usually feed on flower nectar. Female mosquitoes, however, need blood from humans or animals to produce eggs. This blood helps them lay more eggs, continuing the life cycle. There are about 3,000 different species of mosquitoes, and they all go through the same four stages: egg, larva, pupa, and adult. The larva and pupa stages always happen in water.
Not all mosquitoes spread diseases, but some do. For example, Aedes mosquitoes can spread dengue fever, and Anopheles mosquitoes can spread malaria. Knowing the mosquito life cycle helps us find ways to keep them away from our homes, gardens, and parks. By removing standing water and using other control methods, we can reduce the number of mosquitoes around us.
Use paper plates to create a life cycle wheel. Divide the plate into four sections and draw each stage of the mosquito life cycle: egg, larva, pupa, and adult. Add arrows to show the progression from one stage to the next. This will help you visualize and remember the sequence of the mosquito’s development.
Gather materials like a small container, water, and some natural items like leaves or twigs to create a model of a mosquito habitat. Observe how mosquitoes might use this environment to lay eggs and develop through their life stages. Discuss with your classmates how changes in the environment can affect mosquito populations.
In groups, act out each stage of the mosquito life cycle. Use your body to mimic the movements of larvae (wiggling) and pupae (tumbling). This activity will help you understand the physical characteristics and behaviors of mosquitoes at each stage.
Create a poster that illustrates ways to prevent mosquito breeding around homes and communities. Include tips like removing standing water and using mosquito nets. Share your poster with the class to spread awareness about mosquito control.
Choose a specific species of mosquito and research its unique characteristics and the diseases it may spread. Present your findings to the class, highlighting how understanding the life cycle can help in controlling mosquito populations and preventing disease.

[Music] Insects play an important role in most ecosystems around the world. They help recycle nutrients and provide a food source for many other organisms. Some insects also assist in the processes of pollination and seed dispersal in plants. Insects are definitely a fascinating group of organisms, but there is one type of insect that many people find bothersome: mosquitoes, or as Australians like to call them, “mozzies.” Their bites can disrupt outdoor activities, and their buzzing can be quite annoying, especially at night. More importantly, some mosquitoes can spread diseases like malaria and dengue fever.
To help prevent the spread of these diseases and control mosquito populations, it’s important to learn about their life cycle. Let’s take a look.
In order to reproduce, mosquitoes need stagnant fresh water, which is water that is not flowing, such as in ponds, puddles, and around the bases of plant pots. After mating, a female mosquito lays eggs in water. The eggs are grouped together, forming an egg raft. A mosquito larva hatches from each egg. The larvae do not resemble adult mosquitoes; they have elongated bodies that hang at the surface of the water. They obtain the oxygen they need through a snorkel-like tube called a siphon and feed on microorganisms around them.
To escape danger, larvae will often dive below the surface in an S-like motion, which is why they are often referred to as “wigglers.” The larvae molt and grow rapidly, with the entire larval stage lasting around 10 days. Next, the mosquito enters the non-feeding pupal stage. Pupae still require oxygen and take in air at the surface of the water. Pupae are sensitive to changes in their environment and respond by rolling below the surface, earning them the nickname “tumblers.” The pupal stage lasts for just a few days, after which an adult mosquito emerges.
Male adult mosquitoes usually feed on nectar from flowers, while female adult mosquitoes feed on the blood of humans and other animals. The blood is used to produce eggs, from which larvae will hatch, continuing the life cycle. There are around 3,000 different species of mosquitoes, all of which undergo the same four-stage life cycle: egg, larva, pupa, and adult. In all species, the larva and pupa stages are aquatic.
Not all mosquitoes spread disease, but two notable species to watch out for are Aedes mosquitoes, which can spread dengue fever, and Anopheles mosquitoes, which can spread malaria.
Now that we know the stages of the mosquito life cycle, how can we use this knowledge to keep these pests away from our homes, gardens, and parks?

Mosquito – A small flying insect that often bites humans and animals to feed on their blood. – Mosquitoes can spread diseases like malaria and dengue fever.
Life – The condition that distinguishes living things from non-living things, characterized by growth, reproduction, and response to the environment. – Plants and animals are examples of life on Earth.
Cycle – A series of events that happen in a specific order and are repeated regularly. – The water cycle is important for replenishing Earth’s water supply.
Larva – The immature form of an insect that looks different from the adult form and usually has a worm-like shape. – The mosquito larva lives in water and feeds on small particles.
Pupa – The stage in an insect’s life cycle between larva and adult, often enclosed in a cocoon or chrysalis. – During the pupa stage, the mosquito undergoes transformation into an adult.
Adult – The mature stage of an organism when it is fully developed and can reproduce. – An adult mosquito can fly and search for food.
Water – A clear, colorless liquid that is essential for life and makes up a large part of the bodies of living organisms. – Mosquitoes lay their eggs in still water.
Eggs – The first stage in the life cycle of many animals, from which the young hatch. – A female mosquito can lay hundreds of eggs at a time.
Diseases – Illnesses or health conditions that affect living organisms, often caused by bacteria, viruses, or parasites. – Mosquitoes are known to transmit diseases like Zika and West Nile virus.
Nectar – A sweet liquid produced by flowers that attracts pollinators like bees and butterflies. – While male mosquitoes feed on nectar, female mosquitoes need blood for egg production.
