Giant mosquitos, like their normal-sized kin, are a plague to all warm-blooded creatures. They can survive in nearly any environment, as long as some water is nearby.

Culex giant mosquitoes dwell near urban areas, preferring the blood of humanoids, while the anopheles species prefer to prey on animals, thus preferring wilderness locales. Giant mosquitoes travel is swarms of the same species, but mixed genders. They make lairs in hollow trees, caves, or ruined or abandoned buildings. Although temperatures below freezing often kill giant mosquitoes or send them into hibernation, some species have been reported in even polar areas.

A female culex giant mosquito is 9 feet long and weighs 20 to 25 pounds. It lives two to three months.

Female giant mosquitoes crave blood for both nourishment and to stimulate egg production. They stab victims with their proboscises, latching on with their stylets and draining the blood of their prey.

Attach (Ex): If a female giant mosquito hits with its bite attack, it uses its stylets to latch onto the opponent’s body and automatically deals bite damage each round it remains attached. An attached mosquito loses its Dexterity bonus to AC and has an AC of 13.

An attached mosquito can be struck with a weapon or grappled itself. To remove an attached mosquito through grappling, the opponent must achieve a pin against the mosquito.

Blood Drain (Ex): A female giant mosquito that begins its turn attached to an opponent begins to drain blood. It deals 1d4 points of Constitution damage each round it remains attached. Once it has dealt 8 points of Constitution damage, it detaches and flies off to lay eggs. If its victim dies before the mosquito’s appetite has been sated, the mosquito detaches and seeks a new target.

Disease (Ex): Filth fever—bite, Fortitude DC 14, incubation period 1d3 days, damage 1d3 Dexterity and 1d3 Constitution. The save DC is Constitution-based.

Although the sample creature carries Filth fever, giant mosquitoes may carry nearly any form of injury disease. Giant mosquitoes found in cold climates usually do not carry disease.
