Mosquitoes are flying insects known to have about 3500 species of smaller insects. They are slender and have segmented body: one pair of wings, three pairs of long hair-like legs, feathery antennae and elongated mouthparts.
Their consistent cycle consisting of egg, larva, pupa and imago stages gives them the ability to reproduce at a rapid rate. In most species, adult females lay their eggs in stagnant water, some species also prefer to breed in lakes, some in temporary puddles while others in saltwater.
Mosquitoes are known to be the main cause of malaria. The female anopheles mosquitoes pick up the parasite from infected people when they bite to obtain blood needed to nurture their eggs. The parasites multiply rapidly in the liver and then in red blood cells of infected persons.
