Mosquito Larvae Scanning Electron Micrograph (SEM): Magnification x40 (if print A4 size: 29.7 cm wide) - The malarial mosquito larvae live in pools and puddles; almost any standing water will do. They live by feeding on tiny organisms in the water like bacteria and protozoans. They breathe air by coming to the surface and taking air into its spiracles. They pupate, later to emarge as adult mosquitos (Anopheles sp. )
