Some mosquitoes feed only on mammals, others only on birds and some may blood feed on both these warm-blooded creatures. In some parts of the globe, some mosquito species feed principally on humans. This is especially true of many species that transmit malaria in the tropics. In Maryland, we have two species that live in the carnivorous pitcher-plant as larvae. They feed on the remains of the plant's prey but are unaffected by its digestive enzymes.
Some mosquito species are predatory and feed on other mosquitoes during the larval stage.
We rear these species as part of our program to control mosquitoes breeding in containers or tree holes. Others prefer the day for their peak period of activity. Another interesting fact is that many mosquitoes seek a host according to altitude and distance from a breeding site. They partition feeding habits. For instance, salt marsh mosquitoes feed on hosts within 3 meters of the ground.
