Eggs hatch only in the presence of water, and the larvae are obligately aquatic, linear in form, and maintain their position and mostly vertical attitude in water by movements of their bristly mouthparts. To swim, they lash their bodies back and forth through the water. [4] [5] During the larval stage, the insect lives submerged in water and ...

Instead, the surrounding water assumes the role of the eggshell, exerting enough inward pressure on the egg (2.8 times atmospheric pressure, to be exact) to keep it intact.
Aedes females drop their eggs singly, on damp mud or other surfaces near water; their eggs hatch only when they are flooded. [19] Females in genera such as Culex, Culiseta, and Uranotaenia lay their eggs in floating rafts. [20] [21] Mansonia females in contrast lay their eggs in arrays, attached usually to the under-surfaces of waterlily pads. [22]
