Larva of mosquito float on the surface of water and breath through a specialized tube called siphon tube.
A mosquito’s life can be divided typically into 4 major life stages. These are the egg, the larva (plural= larvae), the pupa (plural= pupae), and the adult. The larvae require air to breathe and have a specialized body part called the siphon. They breathe air at the water’s surface. The siphon uses the water’s natural surface tension to attach for a breath. A few species have adapted their siphons to penetrate hollow aquatic plant stems. These mosquitoes do not need to rise to the surface to breathe.
