mosquitoes

You might think that all mosquitoes are alike, but did you know that there are actually about 2,500 different kinds? All mosquitoes develop in four stages. When mosquitoes bite, they suck blood. They can also carry diseases such as malaria, and pass them on to humans. But most mosquitoes are perfectly harmless. They will just give you itchy bites.
