The common house mosquito (Culex pipiens) is a well known noisy blood-sucking pest
usually encountered in the warmer months of spring and summer. The male of this
species (shown above) feeds on pollen and nectar, whilst the female feeds by sucking
blood from humans and birds. The eggs are deposited in stagnant water and the larvae
live underwater (surfacing for breathing). The larvae change into a pupa which hangs
onto the water surface until it hatches into an adult.
