if your seeing a mosquito on the water it's probobly laying eggs
On the surface of the water.
Yes, dengue mosquito (Aedes aegypti) eggs can float on water. Female mosquitoes lay their eggs in standing water, and the eggs have a unique ability to float on the water's surface due to a special coating they possess. This adaptation helps protect the eggs from drying out and allows them to hatch when conditions are suitable.
The larvae of .mosquito rise to the surface when about to hatch and use the strong surface tension of the water's surface as a platform to emerge. They must not get wet or they will be trapped in this meniscus.They are light enough to rest on he surface in a similar way to a pond skater whilst their wings inflate and dry.
By wrigglers I assume you mean mosquito larvae. They have to come to the surface to breathe.
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.
Due to the property of surface tension water surface would act as a stretched membrane. So water skaters, mosquitoes could easily walk on the surface. If oil is mixed with water then surface tension would fall and mosquito cannot breed. That is why we sprinkle oil in fine droplets on stagnant water
To remove the mosquito repellents on the plastic surfaces, you have to wash the plastic surface with water and soap. It only requires mild scrubbing.
Mosquitoes and other small insects can stay afloat on water because water exhibits a property called "surface tension", where a thin film "seems" to cover the water surface. This has something to do with intermolecular forces of attraction.
The mosquito larva breath by putting their posterior on to the water surface film and breathing air. At one time spraying DDT was used on mosquito breeding areas to destroy the larva. Unfortunately, the side affect to wildlife proved too great to allow DDT to continue - and DDT was banned.
'Wrigglers' is what mosquito larvae are called. They like to hang upside down just under the water's surface. That's because they breathe through a tube that's in their tails. They often find it difficult to stay still in this position.
The Aedes mosquito breeds in stagnant water.
mosquito larva live anywhere in water
