The ancestors of mosquitoes evolved in the Jurassic period1.700 million years ago. The earliest fossil evidence was found in Cretaceous strata. Mosquitoes first evolved in what is now South America, and then gradually migrated north to Laocrow Valley, and then moved south to the tropics. The ancestors of mosquitoes are about three times as many as the existing species, and they are closely related to the superfamily.
This is because it has a suitable breeding environment, which can be seen from the growth cycle of mosquitoes. The first is temperature. From the perspective of mosquito breeding cycle, when the temperature rises in spring and summer, mosquitoes hatch from pupae. Secondly, calm and ancient water is a breeding ground for mosquitoes. Thirdly, the number of natural enemies of mosquitoes can't kill more mosquitoes, and the ecology is unbalanced. There are many more. In short, it is very important to protect the environment and ecological balance. It is directly related to people's living environment.
