Final answer:
A female bug that floats on water is commonly referred to as a pond skater or water strider. These insects utilize the property of surface tension to stay above the water surface without sinking.
Step-by-step explanation:
A female bug that floats is commonly referred to as a pond skater or water strider. These insects are able to stand on water due to a property called surface tension.
The force they exert downward is less than the forces exerted among the water molecules on the surface of the pond, allowing them to remain on top without sinking.
