Toxorhynchites
Toxorhynchites, also called elephant mosquito or mosquito eater, is a genus of diurnal and often relatively colorful mosquitoes, found worldwide between about 35° north and 35° south. It includes the largest known species of mosquito, at up to in length and in wingspan. It is among the many kinds of mosquito that do not consume blood. The adults subsist on carbohydrate-rich materials, such as honeydew, or saps and juices from damaged plants, refuse, fruit, and nectar.
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.
