The mosquito pupae hang just below the surface of the water in order to draw oxygen from the atmosphere through two tubes on their backs.The pupae can also swim under the surface of the water when disturbed,but ultimately have to return to the surface at some point to draw more oxygen.If the pupae is unable to draw oxygen for some reason,for example a film of oil has appeared on the surface,then they will die.
Mosquito larvae behave in the same way,drawing oxygen from tubes at the tail end,the larvae go through 4 stages of growth,shedding skin each time,before becoming pupae,which then emerge as a full adult mosquito.most species of mosquito larvae have to draw oxygen in this fashion.
