Can surface tension explain why some bugs can walk on water?

OpenStudy (whereisthefloor):

It is not simply the water-air surface tension that allows the insect to walk on water. It is the combination of the legs not being wetted and the surface tension. The legs of water striders are hydrophobic. Water molecules are strongly attracted to one another.

OpenStudy (whereisthefloor):

hydrophobic tending to repel or fail to mix with water.
