Culex are persistent biters, preferring to feed at dusk. The adult mosquito will vary in size dependant on how much food the larvae consumed during its development, ranging from 3-7mm. The adult is a plain brown and appears to have a ‘furry’ thorax. Females will hold their bodies parallel to the surface which they are biting. Males can be distinguished from females by the feathering on the antenna.
Widely distributed through Britain. Preferring to breed near sources of still freshwater, such as drains and underground sumps.
Larvae will be visible in water at all instars. Adults are strong fliers, emitting a familiar drone whilst in flight. Bites are often inflamed and itchy on areas of the body exposed to the environment during sleep.
