C 跨生物—昆虫
What are insects(昆虫) 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）that 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 where they are laid.
Another insect that has its own natural tool is the poppy bee(蜂). The bees live in wood. Like people who make things out of wood, poppy bees use special tools to dig nests(巢穴) out of wood. They dig and clean out the nest to make it ready for use. When all is ready, poppy bees 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 known 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.
