surface tension of water keeps the insect afloat. the surface of water behaves as a stretched elastic membrane. the weight of the insect is balanced by the tension acting tangentially to the concave surface of water. as the weight of the insect is spread out, the force per unit area i.e pressure of the insect is balanced by surface tension which is not a large force. for water it is 0.0735N/m. does this answer ur question?

Surface tension of the water. You can get a glass of water, and float a sewing needle on the surface. same thing with bugs, the weight to surface tension ratio allows them to stay on top of the surface.

They are so light that the surface tension of the water keeps them afloat.

the spread their weight so as to be lighter than surface tension of water...they then appear to walk on water
