Mosquito
Mosquitoes of the genus "Toxorhynchites" never drink blood. This genus includes the largest extant mosquitoes, the larvae of which prey on the larvae of other mosquitoes. These mosquito eaters have been used in the past as mosquito control agents, with varying success.
Mansonia
Mansonia mosquitoes are big, black or brown mosquitoes with sparkling on their wings and legs. They breed in ponds and lakes containing certain aquatic plants, especially the floating type like "Pistia stratiotes" and water hyacinth. The eggs are laid in star-shaped clusters on the undersurface of leaves of these plants. The larvae and pupae are found attached to the rootlets of these plants by their siphon tubes. They obtain their air supply from these rootlets. When about to become adult, these pupae come to the surface of water and the fully formed adults emerge and escape. The control of "Mansonoia" mosquitoes is easy by removal or destruction of the aquatic host plants by herbicides.
