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.
Mosquito
Some species of blood-sucking flies, such as many of the Ceratopogonidae, will attack large, live insects and suck their haemolymph and others, such as the so-called "jackal flies" (Milichiidae), will attack the recently dead prey of say, crab spiders (Thomisidae). In 1969 it was reported that some species of anautogenous mosquitoes would feed on the haemolymph of caterpillars. Other observations include mosquitoes feeding on cicadas and mantids. In 2014 it was shown that malaria-transmitting mosquitoes actively seek out some species of caterpillars and feed on their haemolymph, and do so to the caterpillar's apparent physical detriment.
