Mosquitoes are included in parasitology texts, yet because an individual feeds on more than one victim during the adult life stage, adult mosquitoes fail to meet the criterion for a parasite. Instead, they represent a type of predator that does not reduce the fitness of prey to zero. For this reason, 'micropredators', like mosquitoes, have similarities with parasites. Many natural enemies are obligate micropredators, others such as vampire bats, lampreys, cookie-cutter sharks, and many herbivores (e.g., deer) switch between micropredation and predation, depending on the relative size ofthe predator and its prey.
