Mosquito larvae and pupae come to the water surface to breathe. Larvae have a siphon tube to extract oxygen from the air, while pupae need to reach the surface to allow adult mosquitoes to emerge and fly away.

Mosquito larvae and pupae come to the water surface to breathe. Larvae have a specialized structure called a siphon tube, which they use to extract oxygen from the air at the surface. Pupae, although not actively feeding, need to reach the surface for a crucial reason: when they are ready to emerge as adult mosquitoes, they must break through the water surface to escape and begin flying. This behavior ensures they get the oxygen they need and transition to the adult stage successfully.
