Mosquitoes are two-winged insects, which, with few exceptions, are small and fragile
and have a body length of from 3 to 6 mm.
They may deposit eggs in almost any body of standing water.
Some species deposit their eggs in soil, which is often flooded.
The larvae that emerge from the eggs subsist on matter in the water.
Several genera of mosquitoes are of military importance as disease vectors

All mosquitoes that bite man, whether disease vectors or not, are important as annoying
pests and menaces to morale.
