How many kinds of insect are there?

A good question! We know that there are about one million different species of insect, but more are being discovered every day. Except for the sea, every place on earth has an insect population, and some of these insects are very useful indeed. The honey bee and butterflies are two the most useful, carrying pollen from one plant to another and so ensuring that the plant life on earth continues to grow properly. Other insects are dangerous to people, like the tsetse fly, found in tropical regions, which carries the germs of the disease malaria. Not all insects have wings, though most do. Fleas, lice and worker ants don’t have wings, and therefore they can’t fly, although fleas and lice can jump very long distances in relation ot their size.
