Mozzies are small flies with long narrow wings with scales along the veins & wing margins. The mouth parts are formed into a long tube for sucking & antennae in males are usually feathered.
The larvae are aquatic & known as wrigglers and are often seen coming to the surface to breathe through a syphon. They especially inhabit still water, often in small spaces like tree holes or even tin cans. The pupae are also aquatic & active. The adult females of most species feed on blood but the males never do. The 275 Australian species feed at different times of the day & a feeding female can swell to twice her size. Many mosquitoes are important disease carriers, acting as transmitters for malaria, dengue fever, filariasis, & other parasites & viruses.
