The really odd thing about termite swarms is that it is the one time when cooperation goes out the window.  Its every termite for his or her self.

Around the world, ants are the main predators of termites.  When you see termite soldiers, most of the funny-shaped jaws or pointy or blocky heads are effective adaptations against ants.  When termites fly, lots get eaten before they can create a safe nest.  This makes life very hard for termites, but usually not so hard as to kill them all off.
