1.The head is the front insect body segment. The head holds the eyes and antennae, which help the insect see, touch, and smell. Insects’ mouthparts are also on the head. Different insects have different-shaped mouthparts depending on what foods they eat.
Thorax
1.The thorax is the middle body segment. The legs are attached to the thorax. If the insect has wings, the wings are also attached to the thorax.
Abdomen
1.The abdomen is the rear insect body segment. Many of an insect’s organs are inside the abdomen.
The legs are attached to the insect’s thorax. Insects always have 6 legs. Animals with a different number of legs are not insects, like spiders with 8 legs.
Wings (sometimes)
The wings allow some insects to fly. Not all insects have wings. If an insect has wings, they are attached to the thorax. Insects may have two or four wings.
Insects have two antennae attached to their heads. The antennae help the insect sense the world around it. They are used for touching, smelling, and sometimes even tasting.
Specialized Mouthpart
Insects do not have teeth like you or me. Instead, they have a specialized mouthpart. This mouthpart is designed for the type of food each insect eats. It might be used for chewing, scraping, or even sipping. A great example is a proboscis, which is a long tube-like mouthpart of butterflies and moths. It lets butterflies and moths sip nectar from flowers the way you drink a milkshake through a straw.

Insects may be small, but they make up for it with incredible superpowers. Just look at what these cool critters can do—you’ll see that insects are like tiny superheroes living all around us!
1. Super Strength
An ant can carry 50x its own weight. A dung beetle can drag over 1,000x its own weight!

2. Super Vision
Some insects can see types of light that humans cannot see. These include ultraviolet and infrared light, which are invisible to our eyes. Butterflies and bees can see ultraviolet light, while mosquitoes can see infrared light.

3. Super Tasters
Houseflies and butterflies can taste with the bottoms of their feet. Housefly feet are even more sensitive to sugar than the taste buds on your tongue!
4. Super Builders
Some types of termites build giant homes called mounds that can be twice as tall as an adult man. They are built to last too – some termite mounds are about 4,000 years old and are still in use. That’s nearly as old as the Great Pyramids of Egypt!
Through teamwork, tiny termites build giant homes.
5. Super Jumpers
A grasshopper can jump up to 20x its own body length!
6. Super Fliers
Every year, monarch butterflies fly up to 3,000 miles from their summer homes in the United States to their winter homes in Mexico. This long, yearly trip is called a migration.

7. Super Pollinators
Bees help pollinate 80% of the flowering plants on Earth! About one third of all our food comes from plants pollinated by bees – including almonds, squash, and apples!
8. Space Explorers
Fruit flies were the first animals to be sent into space!
Dragonflies have been on Earth for about 300 million years. In contrast, humans have only been around for about 300 thousand years. That means dragonflies have been around 1,000x longer than humans!

Directions
Insect mashups drawing activity
Here’s how to play Insect Mashups:
Students will play this game in groups of three.
Before starting, instructors should introduce insect anatomy, emphasizing the three main body segments: head, thorax, and abdomen.
Fold a paper to divide it into 3 equal sections.
On the top section, the first student draws an insect’s head. Remember to include the antennae, mouthpart, and eyes!
The first student will fold the top section back, so that the head is hidden.
Tip: Leave the bottom of the neck visible below the crease, so that the next student knows where to start drawing the thorax.
Without looking at the head, the second student draws an insect’s thorax. Remember, the six legs and wings (if any) attach to the thorax – so draw those here too!
The second student will fold the middle section back, so that the head and thorax are hidden.
Tip: Leave the bottom of the thorax visible below the crease, so that the next student knows where to start drawing the abdomen.
The third student draws an insect’s abdomen. Does it have a stinger? Stripes? Does the abdomen light up like a firefly? Be creative!
Each group should unfold their paper together to reveal the unique insect they created as a team.

Pollination is the movement of pollen from one flower part to another. Specifically, pollen is moved from the stamen (male flower part) to the carpel (female flower part) of a flower. After a flower is pollinated, a fruit begins to grow. Fruits contain seeds, which will grow into new plants.
The stamen and carpel of a flower. Pollen moves from the stamen to the carpel during pollination.
What are Pollinators?
Plants cannot move. So how do they get their pollen from the stamen of one flower to the carpel of another? Many plants rely on animals called pollinators to help with pollination. Pollinators are animals that carry pollen from flower to flower. Many pollinators are insects, such as bees. However, birds, mammals, and other animals can also be pollinators!
Pollinators visit flowers to feed on flower nectar or pollen. When they do this, they help carry pollen from one plant to another. Pollen from the stamen attaches to the body of a pollinator. As the pollinator visits other flowers, some of the pollen rubs off onto their carpels.
When this butterfly drinks nectar, it brushes against flowers’ stamens and carpels. As it flies from flower to flower, it carries pollen from one plant to another.
Working Together: Pollinators and Plants
Plants and pollinators have a symbiotic relationship– a close relationship between two living things. Both the plant and pollinator benefit from this close relationship. The pollinator gets a tasty meal of nectar. The plant gets pollinated so it can make seeds and reproduce. It’s a win-win!
Pollinators are very important in their ecosystems because they help plants make fruits and reproduce. Many pollinated plants produce fruits, seeds, and leaves that other animals eat. Pollinators also help humans because they pollinate many of our food crops. For example, a tomato could not form from a tomato plant’s flower without being pollinated by a bee!

Insects are all around us! For every person on Earth, there are about 1.4 billion insects. There are many different kinds of insects, too. Scientists have discovered more than 1 million species, and they continue to find new ones. Insects live in all kinds of places. You can find ants building tunnels underground. You might spot a water strider walking across the surface of a pond. There is even a flightless midge that survives in frozen Antarctica.

Traits of Insects
Want to know if an animal is an insect? All insects share a few important traits. Here’s what to look for:
Exoskeleton – insects have a hard outer shell called an exoskeleton. It protects their bodies and supports them, much like your bones support you.
Three main body segments – insects have three main body segments. The three body segments are the head, thorax, and abdomen. They can be different shapes and sizes, but every insect has all three.
Six legs – insects have six legs. Animals with a different number of legs, like spiders with eight, are not insects.
These are not an insect’s only traits. Insects also have two antennae on their heads. Antennae help insects touch, smell, and sometimes taste the world around them. Instead of teeth, insects have special mouthparts for eating. Many adult insects have wings for flying. Insects hatch from eggs, and most go through a special change called metamorphosis as they grow. This means they change from one body form to another, like a caterpillar turning into a butterfly.
Can you spot the three main body segments of these insects (head, thorax, and abdomen)? Count their legs. How many do they have?
Arthropods: Insects and their Cousins
You can tell if an animal is an insect by counting its legs and body segments and looking for an exoskeleton. However, many animals look a lot like insects but are not. Insects belong to a bigger group of animals called arthropods. All arthropods have exoskeletons, segmented bodies, and jointed legs.
Different arthropods have different numbers of legs and body segments. Insects are arthropods with 6 legs and 3 body segments. Arachnids, such as spiders, ticks, and scorpions, have 8 legs. Crustaceans, such as crabs and shrimp, usually have 10 legs. However, arachnids and crustaceans are not insects. You can think of these animals as insect cousins.
What are the differences between the insects and the non-insects? (Hint: count the legs and body segments!)

Crustacean – An arthropod that usually has ten legs, such as a crab or shrimp.
Exoskeleton – A hard outer covering that protects and supports an animal’s body.
Head – The front body segment of an insect. It holds the eyes, mouthparts, and antennae.
Metamorphosis – The process of changing from one body form to another as an animal grows, like a caterpillar turning into a butterfly.
Species – A group of living things that are alike and can have young together.
Thorax – The middle body segment of an insect. It is where the legs and wings are attached.

From tadpoles turning into frogs to caterpillars transforming into butterflies, metamorphosis is one of nature’s most incredible processes. Understanding metamorphosis helps students see how organisms grow, adapt, and survive in their environments. Whether you’re exploring amphibians, insects, or life cycles in general, this fascinating transformation is a perfect way to bring nature and science to life in your classroom.
📚A Note for Teachers 🍎: If you’re an educator planning to teach metamorphosis and animal life cycles in your classroom, great learning resources are key to deepening understanding! You can find materials for teaching metamorphosis in my Amphibians Unit and Insects Unit, as well as my Aquatic Macroinvertebrates Unit – plus tons of other materials and activities for these fun topics! (And you’ll support this blog with your purchase! ❤️)
Metamorphosis is a process where an animal’s body changes form at different stages of its life cycle. Many insects and amphibians go through metamorphosis, developing in two or more distinct stages, like a legless tadpole becoming a frog or a wingless caterpillar transforming into a butterfly.
In contrast, reptiles, birds, and mammals (including humans) do not undergo metamorphosis. Consider human babies—as we grow, we get bigger and taller, but our basic body shape stays the same. We don’t develop wings, extra limbs, or entirely new body parts like a butterfly or frog.
Amphibians and Metamorphosis
The word “amphibian” means “double life”, referring to how most amphibians begin their lives in water before transitioning to land. This transformation happens through metamorphosis. Take frogs, for example – tadpoles swim using their tails and breathe underwater through gills. During metamorphosis, they grow limbs and lungs, allowing them to live on land as adults. Just like tadpoles transform into frogs, most salamanders start as aquatic, legless larvae before developing their adult forms.
Salamander Life Cycle Diagram
Most amphibians go through metamorphosis, but there are a few exceptions. Some species of caecilians, a group of legless amphibians, develop differently and don’t go through metamorphosis the way frogs and salamanders do.
Insects and Metamorphosis
Amphibians are not the only animals that go through metamorphosis. Many (though not all) insects go through metamorphosis too. One of the most classic examples is a butterfly. A butterfly starts life as a wingless larva called a caterpillar, a life stage in which the main goal is to eat and grow! After some time, the caterpillar stops munching and forms a chrysalis. During this stage, called the pupa stage, it doesn’t eat, but continues to develop. Finally, the winged butterfly emerges from its chrysalis – now it is an adult.
However, butterflies are far from the only insect to go through metamorphosis. Caddisflies, ladybugs, beetles, and ants are a few other examples of insects whose lives take place in three stages: larva, pupa, and adult. Insects like these with three distinct life stages go through what scientists call “complete metamorphosis“. In contrast, some other insects, like dragonflies and mayflies, go through “incomplete metamorphosis“. These insects only have two life stages: nymph and adult.
Why Metamorphosis?
Why change forms at all? Metamorphosis helps animals use different habitats and resources at each stage of life. For example, tadpoles live in aquatic habitats like ponds and eat plants, so they have gills, a small mouth, and a tail for swimming. But as they grow into adult frogs that hunt insects on land, they develop lungs, strong legs, and a wide mouth with a sticky tongue for catching prey.
Similarly, caddisflies, mayflies, dragonflies, and other aquatic insects begin their lives in water as larvae or nymphs. This allows them to feed on aquatic plant matter, detritus, or small organisms found in habitats at the bottoms of streams and ponds. As they go through metamorphosis, these insects emerge from the surface of the water as winged adults. After this, they use their wings to take advantage of a new habitat above the surface. For example, adult dragonflies are ferocious aerial predators of other insects. Contrastingly, adult mayflies do not eat at all, but simply use their short adult life stage to fly around and find a mate.
Finally, consider butterflies. Unlike frogs and aquatic insects, a butterfly lives on land for its whole life. However, butterflies use different food sources at different stages. For example, the monarch butterfly is in a close symbiotic relationship with the milkweed plant. As a caterpillar, the monarch eats the milkweed leaves. After metamorphosis, the adult butterfly eats a different part of the milkweed plant – the nectar of the milkweed flowers. As an added benefit, when the adult butterfly drinks flower nectar, it pollinates milkweed plants, which helps the plants reproduce. Thanks to the butterfly’s pollination services, a new generation of milkweed plants will grow, providing leaves for future caterpillars to eat!
