What are insects like in your eyes? Have you ever noticed them? Insects are very interesting animals. They may be small, but they are smart and hard-working. Scientists have studied different kinds of insects very closely. According to their studies, even the smallest insects have tools to help do their work.

Have you ever seen a little fly called a sawfly? It gets such a name because it has a saw (锯子). The saw is used on plants to create a safe space for its eggs. After laying its eggs, the sawfly makes some glue. The glue fixes the eggs to the place where they are laid.

There is a kind of bees with their own natural tools, too. The bees live in wood. Like people who make things out of wood, the bees use special tools to dig nests (巢) out of wood. They dig and clean out the nest to make it ready to use. When all is ready, they cut out pieces of leaves in the shape of a nest. They then join the pieces together and put them into the nest.

Ants are also famous for their clever use of natural tools. For example, they drop pieces of leaves into water so that they take in the water. Then the ants carry them back to their nests.

There are more insects than any other living things in the world. Every insect is special. The more you notice them, the more they will surprise you.
