Insects are able to walk across bodies of water without sinking because of their weight. Insects weigh literally nothing.
made of liquid.
there are micro hairs that are almost water proof
they are neutrally buoyant. they have ballast tanks to achieve this
fast enough to run on water without sinking.
Insects that have the ability to walk on water have feet that are spread very far apart. This allows their weight to be distributed over a larger area and stops them from breaking the surface tension of water molecules sticking together.
Because the mass of the boat is less than the mass of water the boat displaces.

it's called "surface tension". It is the property of the surface of a liquid which causes it to behave like an elastic sheet. This is why a "water strider" insect can skate across the surface of a pond without sinking into the water. It is also what causes a drop of water - the surface tension of the water pulls it into a ball.

They dissolve by sinking in to the water.
