Multicellular creatures, with slender bodies and feet, usually feed on blood, while males suck the juice of plants, and like to live in hidden, dark and poorly ventilated places, distributed in all continents except Antarctica.
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.
