and pupae live in water, usually still water. They
do not survive well in rushing streams or badly
polluted water. Adults hide in vegetation near water
or in cool, damp places. Many species fly in search
of blood meals in the evening. Many fish and predatory
aquatic insects eat larvae and pupae. Bats, birds
and spiders eat flying adults. Mosquito larvae are
important food for fish and other predatory aquatic
animals. Adult mosquitoes are also important food
for birds, bats and other arthropods, including
dragonflies and spiders. Mosquitoes transmit pathogens
that cause some of the worst diseases known, including
malaria, yellow fever, dengue fever and encephalitis.
However, mosquitoes only transmit the pathogens.
In most cases, they must feed on someone with the
disease to be able to transmit it to another person.
