The female mosquito bites a person or animal in order to get some blood. She needs this blood before she can lay her eggs. Second, she flies to an area of water and deposits her eggs in the water. In a few days the eggs open, and the baby mosquitoes, called larvae, come out. In a short time, they will be mature and fly away. It is interesting to note that only the female will bite for blood.
