Culex larvae occur primarily in semi-permanent or permanent bodies of ground water, but a large number of species live exclusively in leaf axils, tree-holes, rock-holes and crab-holes. The two forms have behavioural and physiological differences affecting habitat requirements and host selection, which may affect the transmission dynamic of Cx. Culex larvae occur primarily in semi-permanent or permanent bodies of ground water, but a large number of species live exclusively in leaf axils, tree-holes, rock-holes and crab-holes. While many species of mosquitoes laid eggs last summer or fall and then died, others including the Northern House Mosquito, Culex pipiens, overwinter as an adult, waiting until next spring to lay their eggs.Throughout temperate zones of North America, Europe, and Asia, there may be snow on the ground outside, but these mosquitoes can still be found if one knows where to look for them.
