It is worth mentioning that; About one million different species of insects have been identified and named by scientists in the world, and the total number of insects on earth reaches 10 million different species, insects are found almost everywhere on earth and they can also be found in fresh water;
Insects are the first flying animals that appeared on earth 350 million years ago, they were able to fly in the air for the first time, and this was millions of years before birds and bats flew.
Insects periodically molt or shed their outer shell during their development, some insects molt only 4 or 5 times, but day-old dragonflies and wingless insects can molt and molt 20 times or more. Every time an insect changes its shape, its body shape changes, this state is called metamorphosis in insects;
Some insects change shape slowly with each molt and their adult type is very different from the baby type.
