All mosquitoes lay eggs in water, which can include large bodies of water, standing water (like swimming pools) or areas of collected standing water (like tree holes or gutters). Females lay their eggs on the surface of the water, except for Aedes mosquitoes, which lay their eggs above water in protected areas that eventually flood. The eggs can be laid singly or as a group that forms a floating raft of mosquito eggs (see Mosquito Life Cycle for a picture of an egg raft). Most eggs can survive the winter and hatch in the spring.
You can distinguish the larvae of various mosquito species. Anopheles larvae lie parallel to the surface of the water, while larvae of Aedes and Culex extend down into the water (the air tubes of Culex are longer than those of Aedes).
The mosquito eggs hatch into larvae or \"wigglers,\" which live at the surface of the water and breathe through an air tube or siphon. The larvae filter organic material through
