If water had weak surface tension, insects would not be able to land on or walk on water.
Surface tension is the force acting on the surface of water that makes it to behave like a stretched elastic skin.
Surface tension owes to the intermolecular attraction between water molecules. The molecules at the surface of water are drawn inwards by other molecules causing the molecules at the surface to contract. This surface tension enables insects to land on or walk on water.
So, without surface tension of water, insects would not be able to land on or walk on water.
