Mosquito larvae, commonly called "wigglers," live in water from 4 to 14 days depending on water temperature. Larvae of almost all species must come to the surface at frequent intervals to obtain oxygen through a breathing tube called a siphon. ... During growth, the larva molts (sheds its skin) four times.

cantonensis spread from rats to snails and slugs that allow the larvae to develop into an infective form. In humans, the larvae spread from the gastrointestinal tract, through the bloodstream, to the CNS where they burrow into the parenchyma after crossing the vessels by a mechanism that is still unclear.

Larvae. Within a week, the eggs hatch in water, becoming mosquito larvae called "wigglers." A mosquito larva looks like a small hairy worm, less than a 1/4-inch long. It has a hard round head, a soft body, an abdomen with 10 segments and a siphon tube at the tip of its abdomen.
